Acacia drepanolobium Sjöstedt

Mimosaceae (Fabaceae)

English: whistling thorn, black-galled acacia Kamba: kiunga, iunga (plural) Kikuyu: muruai Kipsigis: mukuruit, muguruit Luo: dunga, adugo, dugna, oduga Maa: eluai, eluaai, iluaa (plural) Mbeere: mugambu, mugunga Pokot: sitowonyon, stoghon (singular), stoghoonei (plural) Rendille: fulaay Samburu: luai, luoi Somali: flai Swahili: mbalibali Teso: eyelel Turkana: eyelel

Description: A spiny bush, shrub or small tree to 6 m high with an open spreading crown, flat-topped at maturity. More commonly a small shrub 1.5-3.5 m. BARK: Grey, usually smooth, older bark finely fissured. THORNS: White, straight, some galled at their base. Galls fleshy, hollow, up to 5 cm in diameter, dark green to reddish purple when fresh, turning dark grey to black and usually inhabited by black or brown ants as they dry. FLOWERS: Numerous, in white heads. FRUIT: A narrow reddish brown pod.

Ecology: Grows in eastern and Central Africa, e.g. Uganda, Tanzania, Ethiopia, Sudan, Somalia and the Democratic Republic of Congo (Zaire). Found in Kenya in, e.g. Kaputei plains, Loita plains, Kedong valley, Lambwe Valley, Ndaragwa, Naivasha and Morupus (West Pokot), commonest at 1,300-2,400 m. Most common in open black clay plains, dry rocky hillsides or wooded grassland. Often the dominant shrub in plains with black cotton soil at medium altitudes; less often in red clay soil and rocky areas. Rainfall: 500-1,300 mm. Zones III - V.

Uses: FOOD: Fresh soft fleshy galls edible (+). Galls have a sweet, often slightly bitter taste. Very young galls are green to dark green, bitter and filled with fluid. As they mature they turn reddish purple and hollow. This is the right stage to eat them. Also at this stage stinging ants bore into them at the thorn base and inhabit them. With age, the galls harden, become fibrous, greyish-black and unpalatable. Inner bark fibre, which has a sweetish bitter taste, may be chewed (Machakos). Galls are a favourite food for herdsmen.

OTHER: Branches are used in fencing. Mature plants are a good source of fuelwood (++). Leaves, shoots and fresh soft galls are good fodder for goats, camels (+++), cattle and donkeys (+). Giraffes like browsing on this plant.

Season: Fresh galls found during active growth, mainly after rainy season. Flowers in October-November in Naivasha and Kajiado.

Status: Locally very common.

Remarks: A quite variable species in Kenya.

Acacia hockii De Wild.

Mimosaceae (Fabaceae)

Kamba: kinyua Kikuyu: mugaa Luo: arumbe, oriang' Maa: enchapalani, orcharpalani (Ngong) Mbeere: munyua Pokot: chuwan Teso: ekisim Tugen: tilatil

Description: A usually small acacia, 2-4 m high with a rather open crown. Occasionally a tree to 8 m. BARK: Yellow to greenish yellow, peeling. THORNS: Paired, straight on relatively few branches. FLOWERS: In yellow or orange heads. FRUIT: Pods reddish brown, narrow, straight or crescent shaped.

Ecology: From West Africa east to Sudan and south to Mozambique. Widely distributed in most parts of Kenya and common on sloping rocky bushed grassland, 0-2,400 m. Associated with poor soils, especially sands. Often the dominant shrub. Rainfall: 650-800 mm or occasionally more. Zones III-V.

Uses: FOOD: Inner bark fibre chewed for its juice which has a sweet taste (+++) (Kamba, Maasai, Mbeere). The gum is edible (Kamba, Maasai, Mbeere).

OTHER: Fuelwood (++), fodder, fence.

Status: May be locally common.

Remarks: The acacia with the sweetest bark string in Kenya.

Season: Flowers in December-February (Kitui, Machakos, Kajiado).

Description: A small- to medium-sized acacia, usually 3-5 m, with scattered branches (especially in young plants) or with a spreading umbrella-shaped crown and low branches (in older plants). BARK: Dark brown to black on the trunk. Branches reddish brown. THORNS: Branches armed with paired strong spines. FLOWERS: In bright yellow to orange heads. FRUIT: A grey to purple-black, straight or slightly curved indehiscent pod up to 12 cm long by 1.2 cm wide, with a whitish bloom and a gummy pulp.

Ecology: A species widely spread in tropical and subtropical Africa and east to India, from Ethiopia and Sudan to north-eastern South Africa and northern Namibia. Widely distributed in Kenya in acacia bushland and wooded grassland, e.g. growing in Kaputei plains (Kajiado), Kedong valley and Kerio Valley, 0-2,500 m. Common in both dry lowlands and highlands. Soils variable from sandy to black cotton. Seems to prefer gravelly red soils. Rainfall: Commonest at 500-800 mm. Zones III - VI.

Uses: FOOD: Bark (Kamba, Maasai, Mbeere) and the gummy fruit pulp (Pokot, Turkana, Rendille) boiled in water, sugar added and drunk as tea (+++). Pods are a famine food (Mbeere).

FOOD/MEDICINAL: Bark and roots boiled in milk, blood (Rendille) or soup, especially by warriors for appetite and general fitness (Maasai, Rendille, Samburu). Tea made from fruit drunk for stomach problems. Boiled root extract drunk as a tea for chest pain, abdominal pain and tuberculosis (Samburu).

MEDICINAL: Bark and root used in the treatment of venereal diseases (Maasai, Kamba, Tharaka). Cold bark infusion drunk to treat nausea caused by drinking milk. Chewed leaf or boiled bark applied on wounds, burns and sore eyes (Samburu). Inner bark chewed or boiled as cure for stomach-ache and diarrhoea (Pokot). Inner bark chewed for sore throat and cough (Maasai). Boiled leaf extract used for chest pain or pneumonia (Maasai). Bark and roots used as an aphrodisiac, and roots for gonorrhoea, impotence and chest diseases (Maasai). Bark decoction given to children for fever (Maasai). Sap from twigs (Pokot) and squeezed pods (Turkana, Pokot, Tharaka) applied to infected eyes. Bark infusion used against "malaria" (Pokot) and for stomach problems in goats (Pokot). Infusion of any plant part used to treat headache (Somali, Boran). Root bark (Mbeere) and fruit (Kamba) decoction used for coughs; boiled bark with fat used for painful joints, backache and stomach ulcers (Pokot).

OTHER: Fencing material, fuelwood (+++), charcoal (+++), fodder for all livestock (+). Bark boiled with meat to soften it (Pokot). Bark used for tanning (Mbeere). Bark and roots are a source of dye for baskets (Machakos). Thorns used for piercing ears (Kamba, Tharaka), removing jiggers (Mbeere) and as plugs for gourds (Kamba, Mbeere). Gum from fruit or bark used for attaching feathers to arrows (Mbeere). Wood hard and durable, used as posts for grain stores (Kamba).

CULTURAL/BELIEF: Ground bark used for rituals (Maasai). Fresh juice from fruit rubbed on eyelids to make them black during dances (Digo). Gum from fruits rubbed on hair by old men (Digo).

Season: Flowers in January (Kitui), May-June (Laikipia) or September-October (Naivasha, Kajiado). Fruits in August-September (Kitui) or October (Laikipia).

Management: Best propagated by direct sowing at site.

Status: Very common.

Remarks: This species is quite variable. Two subspecies occur in Kenya: ssp. subalata (Vatke) Brenan (syn: A. subalata Vatke) which is by far the commonest; ssp. leiocarpa is a coastal subspecies (Malindi, Pate Islands, Kiunga, into Somalia) with hairless fruit and young branches. At least seven subspecies are recognized, the others being found outside Kenya.

Acacia senegal (L.) Willd.

Mimosaceae (Fabaceae)

Borana: burra diima, sadeema, sapans diima, iddado, baabido (gum) Daasanach: dang'ite Digo: kikwata English: gum arabic tree, Sudan gum arabic Gabra: iddaad'o Ilchamus: lderkesi Kamba: king'ole (Machakos), kikole, king'olola (north Kitui) Luo: kiluor, otiep Maa: olderkesi, enderkesi, interkes (plural), olbida Mbeere: mung'othi Orma: bura-diima Pokot: chemanga, chemankayan Rendille: hadhaadh, mirgi-abah (gum) Samburu: lderkesi, manok (gum) Somali: edad, edad-geri, adad, edaad Swahili: kikwata, mgunga Teso: ekunoit, ekodokodoi Turkana: ekunoit

Description: Shrub or small tree up to 9 m tall, more often 2-4 m high. Crown flat in mature trees. BARK: Scaly, yellowish brown or grey-brown. Branches armed. THORNS: Spines brown-black, usually arranged in threes at the leaf nodes, the middle one recurved, the others directed forwards. FLOWERS: Buds red, opening to long white or cream spikes, borne in twos or threes or singly. FRUIT: A flat brown, papery, prominently veined dehiscent pod to 10 cm long by 2 cm broad, often slightly constricted between some or all seeds. Seeds usually 3-5, greenish brown, flattened with a circular outline.

Ecology: From West Africa east to Egypt, south to South Africa and Namibia. Also found in Asia. Grows in Kenya, e.g. on Homa Hill, in the Rift Valley, Lokitaung and Mutha hill in dry Acacia-Commiphora bushland and wooded grassland, often forming a pure stand on raised rocky ground in very dry areas, 100-1,700 m. Prefers well-aerated soils, especially rocky, loam or sandy soils. Rainfall: 200-800 mm. Zones III-VII.

Uses: FOOD: A clear edible gum is produced by this tree (+++). This is the best acacia gum in Kenya, much treasured by pastoralists. To induce gum formation, a section of the bark is wounded or stripped off. In the wild state gum production is induced by natural factors. Plants in arid areas or in the dry season tend to produce better gum. This species produces the well-known gum arabic used in pharmaceutical, food and confectionery industries and in the manufacture of glue.

MEDICINAL: Juice obtained from fruits is used as eye medicine (Ilchamus).

OTHER: Fuelwood (++), charcoal, house poles (+), fencing. Bark a source of fibre. Leaves are goat (+++) and camel (++) fodder.

COMMERCIAL: Commercial gum is collected from the wild (Wajir, Mandera, Isiolo, Marakwet, Garissa, Samburu) mainly by children and women. It is usually picked for export to the Far East and Europe. The gum trade in Kenya is less lucrative than in Sudan and Somalia. The main reason is the poor quality of the gum, mainly due to the fact that various grades and types are mixed.

In Kenya, the gum exudes from the tree mainly as a result of natural causes or stress. In the Sudan, the business is old and well established. Here the plant is purposely injured during tapping to induce gum formation. The gum is ready for harvesting about a month after tapping. Collecting can be done over two or more months. Tapping may begin when the tree is four years old and a tree may produce gum up to the age of 15-20 years. Tapping tends to destroy the bark thus lowering production. In the Sudan, tapping is done with a small axe, mainly by removing a long strip of the outer bark from the branches, and is normally done in the dry season when the plant is in stress. The tappers are experienced and hence the quality is good. Kenyan gum, on the other hand, is traditionally collected by pastoralists. Until recently, the business only attracted a few Somali traders, but now the business is attracting full-time collectors and thus the quality of gum is improving.

The potential for development exists. High densities and sometimes pure stands of this species have been found in parts of Turkana and Baringo Districts, especially in northern Baringo, in Kakuma and along Kapedo-Lokichar road. Training of collectors, improved collecting methods and more organized marketing would be the way forward in developing this resource as the market for gum arabic is far from saturated. Currently the Sudan is the largest producer. Others include Mali, Senegal, Mauritania, Chad, Ethiopia and Somalia.

Season: Gum production is highest in August-September and February-March. Flowers in July (Kitui); fruits in August-September (Turkana, Baringo, Ngong).

Management: Best propagated by seed. Soaking in water for a day or nicking may improve germination.

Status: Locally common.

Remarks: This species is extremely variable. At least three varieties are found in Kenya:

· var. Senegal. Distribution: Moyale, Homa Hill, 100-1,700 m.

· var. kerensis Schweinf. Distribution: Lokitaung, Baringo, Mutha, 460-1,130 m. Gum of less superior quality than that of var. senegal.

· var. leiorachis Brenan. (Orma: bura-diima, Somali: adad-gher). This species often hybridizes with Acacia mellifera in Kajiado.

Acacia seyal Del.

Mimosaceae (Fabaceae)

English: whistling thorn Borana: waachu, waachu-adi, waaqu-hallu Gabra: iddaado, iddad'o Ilchamus: lerai, lera Kamba: kisewa (Machakos), mweya Kikuyu: mugaa Kipsigis: mugurit Luo: ali, ale, arombe Maa: olerai, elereta, elereta-nanyokie, oljerai, olerai-oibor (Ngong) Marakwet: rena, renon (plural) Mbeere: mureera Pokot: rena, chowogh, chuwugh Rendille: fulai Samburu: lerai, lera Somali: fullai (Mandera), fulai Teso: ekoramai Turkana: ekoromait, echekereng

Description: Thorny tree up to 10 m high with an open flat-topped crown at maturity. Trunk often with many bulging knots. BARK: Yellowish to greenish white or orange-red and powdery on the surface, green inside. THORNS: White, long, straight, in pairs. They may or may not be galled. FLOWERS: In bright yellow to orange fluffy heads. FRUIT: A slightly curved, narrow dehiscent pod.

Ecology: Widespread in eastern Africa from Egypt in the north to Malawi and Zambia in the south. In Kenya, absent in the coastal zone but widespread in the drier parts of the country in open or bushed grassland and woodland, especially at the foot of hills and on plains, 200-2,200 m, more common at about 1,500 m. Often found forming pure stands. Common on black cotton and rocky soils, less frequently on red soils. Zones III - V.

Uses: FOOD: Inner bark fibre chewed for its nice rather sweet taste (++). The tree produces an excellent clear gum (+++). Bark is ground and used to make tea (Maasai).

OTHER: Poles, fodder (++), bee forage, fuelwood (++), dye, charcoal (++).

COMMERCIAL: Gum occasionally exported along with gum arable but is less valuable as it cracks with time.

Season: Flowers in September-October (Naivasha, Kajiado).

Management: Best propagated by seed. Soaking in water for a day or nicking may improve germination.

Status: Common.

Remarks: Two varieties of this species occur in Kenya:

· var. seyal is the more common of the two and has no galls. Distribution: From Uganda and Tanzania north to Egypt. Altitude: 550-2,200 m.

· var. fistula (Schweinf.) Oliv. (Borana: wachu dima, Somali: fulaii wajol) has ant galls. Distribution: Baringo, Wajir, Isiolo, Marsabit. From Sudan, Somalia south to Malawi, Mozambique and Zambia. Altitude: 200-1,750 m. Use: Gum edible and of some commercial value.

Acacia xanthophloea Benth., (English: fever tree, Naivasha thorn, Kamba: mweya, Maa: olerai) is a much larger acacia. It usually has the same uses and local names as A. seyal. Ecology: Most drier parts of Africa, and East Africa south to eastern Zimbabwe and KwaZulu Natal in South Africa.

Common at medium altitudes 1,400-2,300 m, especially Nairobi, Kajiado, Narok and Naivasha, especially in riverine conditions or places with high groundwater. Zones III-IV.

Acacia tortilis (Forssk.) Hayne

Mimosaceae (Fabaceae)

syn: A. spirocarpa A. Rich., A. raddiana Savi

Borana: dadach, dadacha, urbu-ree (fruits) Daasanach: seech-geebe, sies-geebe (plural) English: umbrella thorn Gabra: d'addaca Ilchamus: ltepes, lkunyi Kamba: mulaa, muaa, ulaa (fruits) Kipsigis: chebitet Maa: oltepesi, sagararam (fruit) Malakote: dadacha, dadwota, dadech (young) Marakwet: ses, sesai (plural), sesoy (plural) Mbeere: mugaa Meru: mugaa Orma: gudis Pokot: ses, sesyai (plural), sesoy (plural) Rendille: gahar khabdo (pods), dahar, qubdo Samburu: ltepes, sagaram (fruits) Somali: qurah Swahili: mgunga Tugen: siesiet, sesya Turkana: ewoi (mature), etir (young)

Description: A spiny acacia, usually 4-8 m high but reaching 20 m in riverine vegetation. Crown narrow when young, spreading, fiat-topped and umbrella-like at maturity. BARK: Longitudinally fissured, dark grey. THORNS: Branches armed at each node with a straight white thorn as well as two short grey sharply recurved spines. FLOWERS: In white heads. FRUIT: A green-yellow to brown pod, often curled into a ring or crescent shape. Seeds smooth, greenish grey.

Ecology: Widespread in Africa from Algeria and Senegal to Eritrea and south to Angola, Namibia and Mozambique. Widespread in Kenya in dry bushland, bushed grassland, wooded grassland, riverine vegetation and arid-land scrub, 600-1,500 m. Soils very variable, from sandy to black cotton. Common in red soils. It is among the most drought-resistant acacias in Kenya. Rainfall: 200-900 mm. Zones IV-VII.

Uses: FOOD: Ripe fresh pods are eaten but seeds are discarded (+) (Maasai, Pokot, Turkana, Somali, Gabra, Daasanach). The crunchy pods have a faint sweet taste. Pods (ng'itit) are pounded, sieved to remove fibrous particles and the flour mixed with blood and eaten (Turkana). The gum is also eaten (Pokot, Turkana, Somali) but is of inferior quality, sticky and may cause choking.

MEDICINAL: Boiled infusion of bark used for diarrhoea and stomach-ache (Pokot).

OTHER: Fuelwood (+++), charcoal (+++), fibre (++) for weaving traditional baskets (Tharaka), kyondo (Kamba), ciondo (Mbeere); ropes and string for building and other purposes are obtained from the bark. This fibre was much used before the introduction of sisal. Thorns used as pins or needles. Fibre chewed for coated tongue, kivuti (Kamba). Debarked roots, which have tiny perforations, are smoked as a remedy for colds (Kamba, Tharaka). Leaves, young shoots, and especially dry pods, are excellent fodder (+++) for livestock, especially goats and camels. Shade and as a meeting place (Turkana). Fencing using dry branches.

CULTURAL/BELIEFS: Roots burned to reconcile families (Tharaka). The tree is believed to attract lightning (Tharaka).

COMMERCIAL: This is the most important acacia among pastoral communities. Pods sold for livestock (Lodwar, Mandera) and human food (Lodwar). Fuelwood and charcoal from this plant are widely sold in small market centres.

Season: Fruits in September-October (Machakos, Kajiado, Kitui, Tharaka).

Management: Seeds taken straight from the pod seldom germinate. Dormancy is broken when they pass through an animal gut, by scarification, bush fire or by hot-water treatment. Should not be planted near homes because of its thorns and the likelihood of attracting caterpillars that feed on the plant at certain seasons. Protection of some areas for some time to give young plants time to grow above the reach of goats may be the best way of increasing this useful tree. As this species is very drought-resistant it has a high potential for desert reclamation.

Status: Locally very common.

Remarks: Two subspecies occur in Kenya:

· ssp. spirocarpa (A. Rich.) Brenan (syn: A. spirocarpa A. Rich.). Fruit hairy and glandular. Distribution: Moyale, Kima (Machakos), Taveta. Eritrea and the Sudan south to Mozambique and Angola.

· ssp. raddiana (Savi) Brenan var. raddiana (syn: A. raddiana Savi). Fruit non-hairy and non-glandular. Distribution: Coastal area, Faza and Manda Islands, Lamu. Algeria and Senegal east to Egypt, Somalia and Kenya.

Acokanthera schimperi (A. DC.) Schweinf.

Apocynaceae

syn: A. friesiorum Markgr.

Borana: karraru English: arrow-poison plant Gabra: k'arraaru Kamba: kivai Kikuyu: muricu Kipsigis: kelyot Maa: olmorijoi Meru: mururu Nandi: keliot Pokot: kelion Samburu: ilmorijoi Somali: marid Tugen: kelyon

Description: A dense round evergreen shrub or spreading sparsely branched tree to 7 m high. BARK: Fissured. LEAVES: Shiny, usually elliptic or ovate. FRUIT: Ellipsoid, to 2 cm long, green, turning green-yellow then dark purple on ripening. Seeds cream with an ivory appearance, compressed on one side.

Ecology: Widespread in East Africa, south to Zimbabwe, Mozambique, Swaziland and north-eastern South Africa. Grows in Kenya in bushland on rocky hillsides, especially on red or black rocky soils, e.g. at Muumandu (Machakos), Ongata-Rongai, Oloosaiyeti hill (Kajiado), Rumuruti (Laikipia), Loita, and Chepelion (north Baringo), 1,200-2,400 m. Common in dry highland forests and bushed grasslands. Rainfall: 500-900 mm. Zone III.

Uses: FOOD: Ripe fruits are edible (+). They are sweet with a slightly bitter taste, but should only be eaten when ripe. Otherwise the whole plant is poisonous. Birds have been known to drop dead on sucking nectar from the flowers.

OTHER: This is the plant used to make arrow poison (Pokot, Kamba, Kipsigis, Embu, Tharaka, Maasai) and by many communities in Central, East and southern Africa. Roots (or other parts of the plant) are boiled in a secluded place for up to 10 hours, adding water up to 5 times. A black viscous substance results which, on drying, may be wrapped up and stored far from people. The poison should never be handled with bare hands if there is any break in the skin. On cooling, the poison may also be pounded to a powder and stored. It is softened again by adding a little water (Maasai). The poison is said to remain potent for a long time. Trees in the hotter areas give better poison and it softens or may melt in cold humid weather. Ash or Aloe sap may be put on top to prevent poison from oozing out (Kamba, Maasai). Acokanthera poison is a lethal cardiac poison only effective when it gets into the bloodstream. This is used against wild game ranging from dikdik to elephant, and small quantities may kill a human in 20 minutes or less. Antidote: In case of accident, squeeze out and suck contaminated blood from the point of entry immediately. (The person doing this should not have sores in his mouth.) Apply paraffin oil (Kitui).

COMMERCIAL: Poison sold in Kitui, said to be obtained from the coast. Arrows with poison from this plant sold (Mwala in Machakos, Tseikuru in Mwingi, Ishiara in Embu, Tharaka, Kitui). Locally, poison experts make this poison and apply it to other people's arrows for a fee (Loita in Narok).

Season: Fruits in May (Narok).

Remarks: A related species, but usually with larger fruits and leaves than those of A. schimperi: Acokanthera oppositifolia (Lam.) Codd, syn: A. longiflora Stapf has edible fruits too (English: arrow-poison tree, Swahili: msunguti, Kamba: kikweo, ngweo (fruit), Kikuyu: kiruru, mururu, kiururu, Mbeere: mururu, Meru: mururu, Taita: msungusungu). It is an evergreen shrub or small tree, normally 3-5 m high, exuding a white latex when any part is injured. Bark grey, rough. Leaves opposite, shiny, elliptic to obovate, broadly ovate with a sharp tip. Flowers in clusters, made up of 5 parts, with a pink tube and white lobes. Fruit oval, 2-3 cm long. Distribution: Kanzalu Range and Kalama (Machakos), Kiambu, Nairobi. Also in Tanzania, south to South Africa. Habitat: Bushland (especially on rocky hillsides) and riverine forest edges and dry highland forests, up to 2,400 m. Soils: Rocky, red clay, clay-loam. Rainfall: 600-1,000 mm. Uses: Fruit edible when ripe (+), sweet and rather bitter. Latex from fruit used as chewing gum by children. Only ripe fruits should be eaten. The roots are occasionally used to make arrow poison (Kamba, Pokot, Kipsigis). A shade and ornamental tree. Season: Fruits in February-March (Machakos). Status: Uncommon. Remarks: Plant roots and other plant parts may be poisonous.

Adansonia digitata L.

Bombacaceae

Chonyi: muyu, mauyu (fruits) Digo: mbuyu Embu: muramba English: baobab Giriama: mbuyu, muuyu Kamba: muamba, mwaamba, mauyu Kambe: muyu, mauyu (fruits) Maa: olmesera Malakote: mubuyu Mbeere: muramba Meru: muramba Orma: yak Samburu: lamai Sanya: yaka Somali: yak (Tana River), jag Swahili: mbuyu, muuyu Taita: mlamba (mbale) Tharaka: muramba, muguna-kirindi

Description: A grotesque-looking deciduous tree to 15 m, with a disproportionately large trunk and twisted branching habit. Trunk soft, fibrous with a smooth grey surface. LEAVES: Digitate. Leaflets to 13 cm long. FLOWERS: Large, white. FRUIT: To 25 cm long, with shiny yellowish green or rusty soft hairs and a hard oval or round shell, often grooved longitudinally. Seeds hard, embedded in a cream or white pulp.

Ecology: Somalia to southern Africa. In Kenya, a common plant in the coastal region but which also grows further inland, e.g. Taveta, Kibwezi, south-eastern Makueni, dry parts of Kitui, Meru National Park and at Torosei in Kajiado, 0-1,300 m. Also planted as an ornamental outside this range. Grows in dry low country in Sterculia-Delonix alata-Acacia-Commiphora bushland and in low, hot, high-humidity coastal areas. Soils varied, but common on red soils, sandy loam and in rocky areas. Rainfall: 300-900 mm. Zones II-VI.

Uses: FOOD: The dry cream-coloured pulp is eaten raw (+++) or is dissolved in water, stirred to a milky state (milk may be added), seeds sieved off and the juice used as sauce (mboga) or added to porridge. Coconut juice is normally added (Giriama). Seeds are roasted like groundnuts (Kitui, Tharaka). Soft tuber-like root tips are cooked and eaten in times of famine. Germinating seed roots are also eaten. Young leaves are used as a vegetable (Giriama, Mbeere). Normally mixed with more coarse vegetables like cassava leaves (Giriama). The pulp-coated seeds (mabuyu) are coloured, sugar-coated and sold as sweets in coastal towns (Swahili).

MEDICINAL: Bark decoction used for steam bathing of infants with high fever. Juice made from pulp is drunk to treat fever (Giriama).

OTHER: Fibre from trunk used as string and for weaving baskets and ropes. To obtain fibre, two cuts, one above and the other below, are made on the trunk and strips of string pulled out (the trunk is fibrous from surface to the centre). Strings for baskets are first chewed to soften them (Kamba). Tree used for placing beehives. Trunks damaged, e.g. by elephants, are used as shelter in shambas (Kamba, Giriama) and as a hiding place during war (Tharaka). Bark used for roofing and making temporary structures (Giriama). Appearance of new leaves or flowers signals the start of the rainy season (Kamba, Mbeere). Fallen trees improve the soil quality considerably. Fruit shells are used as fuelwood, containers, bowls and for making a variety of items, including rat traps (Giriama). The fruit pulp mixed with fig-tree latex is used as birdlime. The shoot and trunk are eaten by elephants, the trunk is also a source of water. Fallen leaves are eaten by livestock.

CULTURAL/BELIEFS: A tree surrounded by complex myths and beliefs among most peoples in areas where it grows. Young plants not cut at all (Tharaka), while large trees are not debarked during or just before rains (Kamba) for fear of rain failure. A sacred and peaceful tree (Giriama). A cut tree is said to bleed like a human being, and this brings bad luck to whoever cuts it (Giriama). A person is believed to turn into the opposite sex if he/she walks round it with a goat (Meru).

COMMERCIAL: Large quantities of fruits harvested and sold in coastal areas. Coloured pulp sold as sweets. Fibre sold in markets (Tseikuru, Mwingi, Tharaka). Baskets (ciondo, syondo) sold in curio shops. Usually more expensive than sisal baskets.

Management: Propagated by seed. Scarify or put seed in boiling water and let cool together. Naturally the seed may take several years before germination, hence the belief that it only germinates after abandoning the present homestead (Giriama). Very slow growing, the tree should not be planted near houses. Lateral roots may reach a length of 100 m or more. It is said to produce its first fruits after 60 years (Kitui).

Season: Flowers in October. Leaves in November-December. Fruits ready in July-September.

Status: Locally very common.

Remarks: Eating much fruit pulp with little else is said to cause weakness and swelling of joints. Up to three types of the tree are recognized by farmers through taste (some sweeter than others), and size and shape of the tree or its fruits as well as season of flowering.

English: purple amaranth Kikuyu: terere Kipsigis: mborochet, mborochik Kisii: emboga Luhya: omboga Luhya (Bukusu): litoto Luhya (Maragoli): tsimboga Luo: ododo Meru: rwoga

Description: A branched, erect or prostrate herb to 50 cm. LEAVES: Long petioles and an ovate lamina to 10 cm long. The tip has a characteristic notch. FLOWERS: Green, borne in axillary and terminal spikes.

Ecology: Grows in tropical and subtropical parts of the world. This species is found in the central and western parts of Kenya, especially Kisii, Kericho, Bomet and Nandi Districts, in wet areas, on waste ground and in cultivated land, 800-2,400 m. Zones I-III.

Uses: FOOD: Leaves and young shoots used as a vegetable (+++) (Kikuyu, Nandi, Kipsigis, Marakwet, Luhya, Luo, Kisii). An important leafy vegetable for the Kisii and Kipsigis who cultivate it in kitchen gardens. COMMERCIAL: Sold in Kericho, Kisii and Kisumu markets. Occasionally seen in Nairobi markets.

Remarks: Two subspecies are recognized by Townsend in Flora of Tropical East Africa:

· ssp. lividus (syn. A. blitum) is generally larger, erect with larger fruit and leaves.
· ssp. polygonoides is smaller and normally prostrate.

Amaranthus dubius Mart. ex Thell.*

Amaranthaceae

Digo: chiswenya English: amaranth Giriama: kiswenya, kiswenya-kithithe (small form) Ilchamus: raprapa, i-okuronit, i-okuroniti Kamba: w'oa, telele (Kitui), terere (Mwingi) Kikuyu: terere Kipsigis: kelichot Kisii: emboga Luhya (Bukusu): emboka, litoto Luhya: lidodo Luhya (Tachoni): lidodo Luo: ododo, omboga Maa: nanyi, nyanyi Marakwet: kipkanding'wa Mbeere: muterere Pokot: ptanya Samburu: nyoni, nterere, ntererei, mir Swahili: mchicha Taita: kichanya, kizenya Tharaka: terere

Description: An erect branched herb up to 1 m or more, resembling the spiny amaranth, A. spinosus, but without spines. Stems ridged. LEAVES: Simple, long petiolate, alternate, usually with an ovate lamina to 8 cm long, veins conspicuous underneath. FLOWERS: Borne in clusters, in the axils and in terminal branched heads or spikes. FRUIT: Covered by bracts and bracteoles which are the more visible structures of the flowering part. Seeds black, shiny.

Ecology: Grows in most tropical parts of the world and usually found in most sub-humid parts of Kenya below 2,000 m. A common herb in most towns in Kenya and commonly found on cultivated land, roadsides and flood plains. Cultivated a great deal in kitchen gardens in western Kenya and among the Mijikenda of Coast Province. Zones I-V.

Uses: FOOD: Leaves and tender shoots are used as a vegetable (+++), sometimes cooked with more bitter vegetables such as Cleome gynandra (Luo, Siaya), black nightshade and Launaea cornuta (coast). This avoids the process of pouring out the water used for boiling the vegetables. A. dubius is a popular choice for improving the taste of many traditional leafy vegetables.

Season: Two weeks after the onset of the rainy seasons, April-September, November-January (coast).

Management: The mature inflorescence is squeezed between the palms to release the seeds which may be broadcast at the required site. Occasionally, weedy seedlings may be uprooted and planted at the required place (coast).

COMMERCIAL: Grown on a commercial scale along the Sabaki flood plains, in Kaloleni near Mombasa and in Wangige near Nairobi. Sold in Nairobi, Malindi, Mombasa, Siaya, Kisumu.

Remarks: Amaranthus dubius is believed to be of American origin. A more recently introduced large-leaved giant amaranth is believed to be a form of this species (Giriama: kiswenya kibomu). It grows much larger, the stems are thicker, leaves are larger and usually blotched purple. The inflorescence is large but seeds are smaller. This form is becoming more popular with farmers. Amaranths are among the most commonly used leafy vegetables in Kenya and most of Africa. Of the 60 or so species of Amaranthus in the world, at least 13 occur wild in Kenya. Many of these (probably with the exception of A. thunbergii, A. sparganiocephalus and A. graecizans) have been introduced from other parts of the world, especially the Americas and Asia. Because of their close resemblance and the fact that many are only newcomers, they are often known by the same local names and used in the same manner. They are among the most nutritious leafy vegetables.

Amaranthus graecizans L.

Amaranthaceae

syn: A. angustifolius Lam., A. silvestris Vill., A. parvulus Peter

Digo: chiswenya Embu: rwoga English: amaranth, prostrate amaranth Giriama: logatsi Ilchamus: raprapa, lokuronit, lokuroniti Kamba: w'oa, woa, telele (Kitui), terere (north Kitui) Kikuyu: terere, terere wa gikuyu Kipsigis: kelichot Luhya (Bukusu): edodo, litoto Luhya (Tachoni): lidodo Luo: ombok-alikra, omboga Maa: nanyi, nyanyi, nyani, embeneyoi Marakwet: kipkanding'wa, kipiriak (plural) Mbeere: muterere, muruoga Meru: rwoga ra kicuka Pokot: ptanya Samburu: mir, nyoni, nterere, ntererei Somali: dargu Swahili: mchicha, mchicha mwitu Taita: kizenya (Mbale), kichanya Tharaka: rwoga Turkana: ekiliton, lokiliton, louyeing'orok, adye

Description: An erect, decumbent or prostrate herb usually branched from the base and often less than 40 cm high. LEAVES: On long petioles and with small lamina (about 4 cm). FLOWERS: Green and borne in axillary clusters. FRUIT: Seeds tiny, smooth, shiny black.

Ecology: Found throughout most of Africa, warmer parts of Europe, tropical and subtropical Asia. The commonest amaranth species in the semi-arid and arid regions of Kenya but also grows in wetter regions on waste ground and as a weed of cultivation. Common on sand deposits along rivers, at roadsides and forest edges. It is most abundant where surface run-off collects in semi-arid lands. It can grow in partially shaded areas under trees. Soils varied, mainly sand and sandy alluvium. Zones II-VII.

Uses: FOOD: The leaves and young tender shoots are used as a vegetable (+++). Later as the seeds mature it is advised to pick individual leaves as stray seeds in food feel like sand in the mouth. The vegetable is normally cooked and eaten with ugali or it may be cooked together with flour to a stuff known as ngunzakutu (Kamba) or atap (Turkana). Leaves may also be mashed with a mixture of maize and a pulse (Kikuyu, Kamba). A major drawback is that leaves of this species are small and collecting enough for a meal can take some time.

OTHER: Fodder (++) for all livestock.

Management: Seeds can be obtained from mature plants by rubbing the flower heads to release them. Passing a light current of air through cleans them of other particles. The seeds may be broadcast soon after the onset of the rains. It can be intercropped with trees as it is shade-tolerant. In the wild, this amaranth sprouts easily soon after the onset of rains, grows fast, seeds and dries as fast, and hence its ability to survive in the arid lands. At maturity the plant sheds the small, black, shiny seeds.

Status: Common, especially in dry areas.

Remarks: Three subspecies have been recognized:

· ssp. graecizans (syn. A. angustifolius Lam.) with a narrow leaf blade and common in seasonally flooded areas,

· ssp. silvestris (syn. A. silvestris Vill.) with a broader leaf blade and more common than the former, and

· ssp. thellungianus (Nevski) Gusev., a rare type, only occurring in Central Province.

Amaranthus hybridus L.*

Amaranthaceae

syn: A. patulus Bertol.

Description: An erect or prostrate branched herb usually 40-80 cm but occasionally attaining the height of a Mandera, especially in cultivation. Stems green or tinted red, ridged. LEAVES: Simple, alternate, green or tinted red with a lamina to 15 cm or more and a long petiole. FLOWERS: Borne in clusters in green, yellow, red or occasionally purple axillary and terminal spikes. FRUITS: Seeds shiny black or cream.

Ecology: Widespread in tropical and subtropical regions of the world and widely distributed in humid to sub-humid areas in Kenya, mainly as a weed of cultivation, in degraded land and built-up areas, along rivers, roadsides and forest edges, 900-2,600 m. Commonest in the middle altitudes and highlands (1,400-2,400 m). Zones I-V.

Uses: FOOD: Leaves and young shoots used as a vegetable (+++). This is the commonest and the most widely used species in the wetter regions. Much of it is picked from the wild or occasionally it is spared when found growing as a weed. In some parts of Kenya, especially in the west, the species is cultivated in small home gardens. The vegetable is very tasty and its large leaves make it a very popular amaranth.

COMMERCIAL: Leaves, and occasionally seeds, sold in Nairobi and some other markets throughout the country.

Season: Rainy season and soon thereafter.

Management: A. hybridus grows easily from the small hard black seeds. Prepare the ground to loosen the soil and to get rid of weeds. The seeds may be sowed by broadcasting or in lines made at 30 cm intervals. As the seeds are tiny, they can be mixed with sand to ensure a more even distribution. Seeds germinate after a few days. Thin out the plants leaving the appropriate distance between neighbouring plants. These will be your first vegetables! Weed as often as necessary. Seed harvesting: At maturity, the flowering head will start losing its natural green colour (or whichever was the original colour). Mature seeds are black, while immature ones are red or pale. Whole heads may be cut, dried in the sun on a polythene sheet and beaten with light sticks to release the seeds. Rubbing between the palms may release more seeds. The seeds and chaff are then winnowed on a tray.

Status: Very common.

Remarks: Two related species are found in Kenya:

· A. hypochondriacus L. (syn. A. patulus Bertol.) has a prominent terminal spike, a more "spiny" look and often has a prostrate habit. It is more common in the higher altitudes.

· A. cruentus L. (syn. A. paniculatus L.) has a more branched flowering head, with a less "spiny" appearance. It is not as common at high altitudes. The red form of this species is also cultivated as an ornamental. These two species are often treated as subspecies of A. hybridus. Ethnobotanical surveys have confirmed that this is one of the introduced amaranth species in Kenya. A. hybridus is of Central American origin.

Amaranthus sparganiocephalus Thell.

Amaranthaceae

Maa: nanyi, nyani Samburu: nyoni Somali: rasso Turkana: edeyea, loyeing'orok, louyeing'orok

Description: A spreading prostrate or erect herb to about 50 cm, often branching near the ground forming a dense mass. LEAVES: Greenish brown, with long petioles and a lamina of about 5 cm long. FLOWERS: Borne in sessile axillary clusters.

Ecology: North-eastern Africa and the Arabian peninsula. In Kenya it grows in abandoned pastoral settlements in semi-arid areas, especially in Kajiado, Samburu, Turkana and Marsabit. 100-1,600 m. Zones V-VII.

Uses: FOOD: Picked and cooked as a leafy vegetable (+) (Maasai, Samburu, Turkana, Pokot, Somali). This plant sprouts quickly soon after rain. It is picked along with A graecizans by pastoral communities in the semi-arid areas of Kenya.

Management: Propagated by seeds.

Status: Uncommon.

Remarks: The species is closely associated with animal enclosures in Maasai land. It is often found along with A. graecizans growing on top of Maasai traditional houses during the rainy season.

Amaranthus spinosus L.*

English: careless weed, prickly amaranth, spiny amaranth Giriama: kiswenya-cha-miya Ilchamus: lkamasei Kikuyu: terere-wa-ng'ombe, terere wa kigombe Kipsigis: mborochet Luo: ododo Mbeere: macica Pokot: sikukuu, chepkuratian Samburu: nairepirepi Sanya: kiswenya-korati Turkana: lookwa, epespes the rest of the local names as for A. hybridus.

Description: A stout, erect (occasionally decumbent) herb about 1 m or more with green or red and usually branched stems. LEAVES: Have a long petiole and an ovate lamina to 10 cm or more. FLOWERS: Spiny and green, forming axillary clusters and in terminal inflorescences.

Ecology: Grows in tropical and subtropical parts of the world, occasionally in temperate regions. The species is widely distributed in Kenya in most areas below 1,900 m. A common plant near livestock enclosures (hence the Kikuyu name for it), in abandoned settlements, along streams, at roadsides, in open grassland and as a weed of cultivation. It is the scourge of farmers at maturity. Zones I-VI.

Uses: FOOD: The species is seldom used as a leafy vegetable (+), picked mostly while still young before the spines have hardened and mainly by communities in the Coast, Nyanza and Western Provinces of Kenya as well as the central part of Rift Valley. The species is not much liked and its use is declining. This species is native of tropical America but was probably introduced to Kenya earlier than A. hybridus.

COMMERCIAL: Leaves occasionally sold, especially in Nyanza and western Kenya.

Status: Common.

Remarks: This species may easily be confused with A. hybridus and A. dubius, but the red stems and spiny nature of A. spinosus are distinguishing features.

FLOWERS: Large, yellow, with a red or purple centre. FRUIT: To 5 cm across, light green, velvety hairy, with a clasping calyx, splitting into five valves on ripening. Seeds dark grey (almost black) and covered with woolly hairs.

Ecology: The only Azanza species found in Africa, from eastern to South Africa. Very common in Machakos and Kitui Districts in open bushland and woodland. Common in Combretum-Terminalia bushland, 500-1,500 m. Soils: sandy or red clay. Rainfall: 600-800 mm. Zones III-V.

Uses: FOOD: Ripe fruits edible and very sweet (+++). Valves are chewed, the gelatinous sweet extract is swallowed and the fibrous remains discarded after chewing. Occasionally stored for up to a month without losing sweetness. Hard dry ones eaten too.

MEDICINAL: Used for coughs (Makueni). Stems and leaves pounded and extract taken against liver problems (Kitui).

OTHER: Fuelwood (+++), shade (++). Fruit juice used as a lubricant for toy wheels by boys (Makueni). Wood strong, finishing smooth and used in carvings, mortars and pestles, wooden spoons, yokes, handles for axes and in the construction of traditional tables for drying utensils (Kamba, Mbeere). The centre poles in huts are usually of this plant (Kitui). The heartwood from some types is said to be very hard and resistant to attack by termites and other insects, hence used for combs and carvings (Kitui).

Season: Flowers in November-December (Kitui). Fruits in August-September and are spoilt by November rains (Kitui). Note: Fruits ripening said to coincide with months of food shortage in Kitui Central, and so an important famine food.

Management: Propagated by seeds, direct sowing. Planted in crop land as well as near homes as an ornamental. Prune lower branches to give it a good shape.

Status: May be locally common.

Remarks: An important fruit plant among the Kamba, especially in times of famine, hence the saying "Mutumia aleele muthoni kulea umutwiiya itoo", meaning a father recalled his daughter from in-laws when they refused to give him this fruit during his visit. Fruits attract the cotton-boll stainer, hence not a suitable tree near cotton fields.

Description: A much-branched spiny shrub or tree up to 10 m high. Crown rounded, dense (but still can be seen through, cf. B. glabra which has a more dense crown and long stout branchlets). BARK: Trunk grey, deeply fissured longitudinally. Branchlets green, with (or without) long straight green spines (up to 10 cm). LEAVES: With a conspicuous petiole to 2 cm long, two leaflets, usually small, greyish green, normally shed in severe drought. FLOWERS: Small, greenish yellow, in leaf axils. FRUITS: Ellipsoid, up to 4 cm long, green. Ripe fruit brown or pale brown with a brittle coat enclosing a brown or brown green sticky pulp. Seed a hard stone.

Ecology: An important tree found from West and North Africa south to Zimbabwe and Angola from arid and semi-arid regions to sub-humid savannah. Found in many parts of Kenya, e.g. in Lambwe valley and Kaputei plains, but rare in the coastal zone. Pound at 250-2,000 m in bushland and wooded grassland. A common tree in open grassland with black-cotton soil. Soils: Mainly red and black-cotton clay. Zones IV-VI.

Uses: FOOD: Ripe fruit is edible (++). The brown fruit shell, which is readily detached from the pulp, is removed. The brown pulp is sucked and the seed discarded. It has a sweet taste, rather bitter nearer the seed. Young leaves and tender shoots are used as a vegetable (Pokot, Turkana, Tugen, Marakwet, Keiyo, Ilchamus). The vegetable is boiled (water may be changed), pounded then fried or mixed with fat (Pokot, Marakwet). Seeds (with shell) or cotyledons (shell removed) are boiled for 2-3 hours and the bean-like cotyledons eaten (Pokot, Tugen, Marakwet). Gum is edible (Maasai). Elsewhere the seeds are a source of oil.

MEDICINAL: Decoction of roots is used for the treatment of malaria (Pokot). Roots boiled in soup used for oedema (sir) and stomach pains (Pokot). Roots are used as an emetic (Pokot). Bark infusion used to treat heartburn (Machakos).

OTHER: Fuelwood, charcoal (+++). Wood hard, durable, worked easily and made into yokes, wooden spoons, pestles, mortars, handles, stools, combs. Resin from stems used to stick feathers on to arrow shafts (Pokot, Turkana) and spear heads on to shafts (Pokot, Maasai, Turkana, Kipsigis), and repair cracks in tool handles, arrows, etc. (Turkana, Pokot). Branches used for fencing. Bark used as fish poison. Animal fodder (++). Elsewhere fruits are used as poison to kill some stages of the bilharzia fluke in water. Even a few are effective. Activity has been reported in other Balanites species, and B. maughamii of southern Africa, with forked spines, is reportedly even more potent.

CULTURAL/BELIEFS: Fire made using this tree used to warm beer gourds for elders (Mbeere).

Season: Fresh new leaves in July-August (West Pokot). Fruits in March-April (Machakos, Kitui, Kajiado).

Management: Propagated by planting seed directly or by raising seedlings in a nursery.

Status: Common.

Remarks: The name olng'oswa (Maa) is mainly used for B. glabra Mildbr. & Schlecht., an evergreen, much-branched dense bush, shrub or small tree 2-4 m high. Branches green, drooping. Spines thick, long, to 10 cm or more. LEAVES: Usually without a conspicuous petiole and usually with two almost round fleshy looking leaflets. FLOWERS: Greenish yellow. FRUITS: Shortly ellipsoid, with light green longitudinal lines. The plant is common in Kajiado and Kaputei plains at 1,400-1,800 m on black soil. The commonest Balanites around Athi River. Ripe fruit pulp is sweet, juicy and eaten (Maasai) but is said to be mildly poisonous, causing a feverish feeling, stomach-ache and even diarrhoea (Maasai). B. wilsoniana Dawe & Sprague (Swahili: mtonga, Giriama: mkonga, Kamba: kivuw'a) is a large, extremely thorny tree (when young) up to 10 m tall. It is only found in the coastal area and in Kibwezi forest. Its leaves and fruits are larger than those of the other Kenyan Balanites species. Fruits are edible. The plant is often infested with caterpillars (maungu) which are collected for food by the Giriama.

Balanites pedicellaris Mildbr. & Schlecht.

Balanitaceae

Marakwet: lomion, lom (plural) Pokot: lomion Rendille: ilbule Samburu: sarai Turkana: elamach

Description: A spiny, often multi-stemmed much-branched shrub or, rarely, a small tree usually 2-4 m high, with a rather narrow crown. Larger spines usually with many smaller ones. BARK: Usually smooth, grey. LEAVES: Leaflets short-stalked, with a rounded apex. FLOWERS: Green. FRUITS: More or less round, 2-3 cm in diameter, green turning yellow when ripe.

Ecology: Grows in eastern Africa south to north-eastern South Africa. Widespread in Kenya, e.g. along the Turkwel River and on Observation hill (Amboseli). Usually along dry watercourses, flood plains, dry bushland, 300-1,300 m. Rainfall: 200 (riverine)-500 mm. Zones V-VII.

Uses: FOOD: Cooked cotyledons eaten (Pokot, Turkana, Samburu, Tugen, Marakwet) (+++). Fresh fruits are bitter and toxic but reportedly eaten fresh in southern Africa. Preparation: Fruits are gathered and pounded (usually after brief boiling) to break open the seed. Two green bean-shaped cotyledons are released. These are washed and then boiled for 8-9 hours. Over-boiling turns the cotyledons into a porridge-like fluid. Water is changed 8-10 times. Salt, ash solution (Pokot), tamarind (Tamarindus indica) (Turkana: Ng'ikebootok), bark of Sclerocarya birrea or Lannea schweinfurthii (Pokot) may be added at the end of the process to remove any remaining bitterness and to improve the taste. The food is eaten like beans, usually alone, occasionally with butter or milk. Uncooked cotyledons may be dried and stored. They can keep for several years.

FOOD/MEDICINAL: Boiled root infusion added to children's milk (Pokot).

MEDICINAL: Root infusion used for fever and diarrhoea (Pokot).

COMMERCIAL: Boiled cotyledons sold in Lodwar town and in some villages, e.g. in Kaputir, southern Turkana.

Season: Fruits in February (southern Turkana, Baringo) or September-October (Turkana, Baringo).

Description: A strikingly tall unbranched palm to 25 m high. Trunk: Smooth to rough, grey, widening high up above the middle. Leaf scars prominent immediately below crown, less prominent below. LEAVES: Fan-shaped, very large, to 2.5 m long, upper half divided into many folded leaf segments. FLOWERS: Green, dioecious. FRUIT: Large, up to 15 cm long by 12 cm wide, smooth, slightly elongate, orange to orange-brown, containing up to 3 seeds surrounded by a fibrous pulp.

Ecology: Widespread throughout the less dry areas of tropical Africa. Open grassland with a high water-table, along watercourses, flood plains, coastal coral sands, often in dense stands. Found at the coast in Kenya, e.g. at Madunguni (Kilifi), Gede ruins and in Shimba forest, western Kenya and around Mandera, 0-1,400 m. Zones III-IV.

Uses: FOOD: Fruit pulp and seed edible (Digo, Giriama) (++). The immature seeds are eaten. Germinating seedlings are reportedly eaten (Uganda). Excellent palm wine, dzova (Digo) is made from sap tapped from inflorescence penducles (stalks). It is reputedly the best palm wine in Africa with a high sugar content (Uganda).

OTHER: Leaves are used in the mat and basket industry. The trunk is tough and termite-resistant. It is used as poles, in construction and as beehives.

Management: Propagated by seed which are best sown directly on site. Grows fast when young but very slowly later. Fallen seeds root easily in humid soil. Root develops well before shoot is seen.

Status: Generally rare but may be locally common. Over-exploitation of the palm for its wood and sap has led to its decline in most areas where it grows.

Remarks: Another palm used for wine production is Elaeis guineensis Jacq. (English: oil palm, Guinea oil palm, Swahili: mchikichi, mjenga, Digo: mchikichi, Pokomo: mchanga, Sanya: metsengwa, Taveta: mposi). It is a tree palm to 15 m high. Young stems covered with persistent leaf bases which are shed with age leaving ridges of scars on the trunk. LEAVES: Dark green, long, borne in a terminal crown. Leaflets with spiny margins. FLOWERS: Monoecious, borne in the leaf axils. Riverine. Uses: An important oil crop (seeds) in West Africa but not in Kenya. Oil is used in the manufacture of margarine, soap and as a lubricant. Palm wine is tapped from the palm in Uganda and West Africa but not in Kenya. Unlike Borassus, the wood is not durable. A rare species in Kenya.

Another important palm is Cocos nucifera (English: coconut palm, Giriama: mnazi, Kamba: munathi, Sanya: madhi, Swahili: mnazi, nazi (fruit)). This palm is grown all over the tropics in hot humid coastal areas and has been cultivated for a long time. In Kenya it is grown along the coastal strip and in a few inland areas as an ornamental plant (Lake Turkana, Lake Victoria, Kitui). An important source of wine, food, thatching material, building poles, fuelwood, shade, oil, leaves for handicrafts and a host of other traditional uses. The oily extract from the coconut flesh, tui (Swahili), is used for flavouring food. It is added to the dish only in the last 5-10 minutes of cooking to avoid boiling and curdling.

Brassica carinata A. Br.

Cruciferae (Brassicaceae)

syn: B. integrifolia (Wes.) Rupr.

English: Ethiopian cabbage, Ethiopian mustard Kisii: chinkongonyira Luhya (Maragoli): likabichi lya manyonyi Luo: kandhira Mijikenda: kanzira-sukuma (Mariakani)

Description: An erect annual herb, often branched, to 1.2 m or more. LEAVES: Pinnately lobed, smaller compared to those of other brassicas. FLOWERS: Yellow, borne in a long terminal inflorescence. FRUIT: A long capsule. Seeds small.

Ecology: Grown in many parts of the world with several cultivars. In Kenya mainly grown in Nyanza and Western Provinces, especially by the Luo and Luhya communities. Introduced at the coast. Occasionally grown in large cities such as Nairobi by the same communities. Also found as an escape in the same areas, 0-1,600 m (in Kenya). A weed of cultivation also grown as a vegetable. Prefers fertile places such as abandoned cattle enclosures. Rainfall: 600-1,600 mm. Zones II - III.

Uses: FOOD: Leaves are used as a vegetable (Kisii, Luo, Luhya, Mijikenda, Suba) (+++). A popular vegetable among the Luo. Leaves mixed with those of akeyo (Cleome gynandra) are boiled, made into lumps, dried in the sun and stored in a clay pot (agulu) as a dry-season food (Luo). This may be eaten with apoth (Asystasia mysorensis) as mboga. Leaves are also fried with meat and used as mboga. Leaves are said to be mixed with those of Solarium nigrum and Cleome gynandra in Malawi. The cooked vegetable has a characteristic sharp odour and it is not bitter. In southern Africa, oil is extracted from the seeds and used for cooking and for rubbing on the skin.

MEDICINAL: Water obtained after boiling leaves is used to treat diarrhoea (Luo).

OTHER: Seeds much liked by birds, hence the Maragoli name.

Management: Grows easily from seeds which are sown in lines or broadcast. Normally grown in kitchen gardens (Luo: sirundi, kirundi) at the homestead to minimize on bird attack (Luo, Luhya). Among the Luo it is grown together with akeyo (Cleome gynandra). Seeds are often mixed with ash when planting to keep off pests. Seeds are also distributed by birds. Plants are normally cut at a height of about 15 cm to induce the plant to produce larger leaves.

Remarks: A plant of unclear taxonomic position and doubtful origin. Some authorities treat B. carinata as a variety of B. juncea (L.) Czern. This species is also found in India (English: Indian mustard). B. carinata is believed to be a native of the Ethiopian highlands. Significant variation in leaf width is found in this species. Some forms have very narrow leaves. Leaves are generally small and there is need for improvement if it is to have potential as a vegetable.

The genus Brassica contains some important exotic species such as the cabbage (B. oleracea L. var. capitata), rape and swede (B. napus L.), turnip (B. rapa L.) and kales (B. oleracea L. var. acephala). (Swahili: sukuma-wiki, Kikuyu: matharu, Kipsigis: sarokel, Luo: badmaro, Kisii: egesusura, Luhya: likabichi). Several of these introduced species have gone wild, especially in the highlands. Kales are becoming more important, especially among urban dwellers, thus replacing cabbage and traditional vegetables.

Peas are boiled, mashed and rolled into balls or boiled with sorghum (Luo). Among the Kikuyu, pigeon peas were important food during ceremonies like circumcision.

OTHER: After harvesting the stalks are cut and used as firewood (rather poor quality, burns fast but an important fuel during the wet and planting seasons). A good plant for crop rotation or intercropping. An important fodder plant during the dry season after crop harvest. The dry leaves and pods remain after harvest and are important food for donkeys, cattle and goats.

COMMERCIAL: Sold in various forms: fresh pods, green peas without pods and dry peas, mainly in central and coastal parts of Kenya and in Nairobi.

Season: Flowers in May-June in Machakos, Kitui, Mbeere and Mwingi. Fruits in July-August in Mbeere, Kitui and Machakos.

Management: May be grown as a pure stand or with other crops. In the low hot regions of Eastern Province it is normally planted during the short October/November rains and harvested in July-August the following year. In Nyanza normally planted sparsely or at the edge of crop land. Harvesting: Once the pods are dry, the fruiting branchlets are cut or broken off and spread on the ground for further drying (especially of leaves and fresh pods). Dry pods easily split open releasing seeds when threshed. These are winnowed on a windy day. Seeds do not store for long without insecticides.

Pigeon pea is still an important crop in semi-arid areas, i.e. Machakos, Makueni, Mbeere and Tharaka-Nithi Districts. In the more humid areas its cultivation has declined because of introduction of other crops such as field peas (Pisum sativum, Kikuyu: minji) and kidney beans (Phaseolus vulgaris L., Kikuyu: mboco, Kamba: mboso, Luo: oganda, Swahili: maharagwe). In many areas increased attack by insect pests (kathoa, Kikuyu, Kamba) at flowering time has reduced yields significantly in recent years, in some cases causing total crop failure.

Pigeon pea is a hardy crop and a preferred food. It may be intercropped with deeply rooted crops such as cowpeas (the creeping type), cassava, pumpkins, gourds and sweet potato. Crops such as maize, beans, millets, sorghum and quick-maturing types of cowpeas are adversely affected. Its potential in the food industry is still not yet fully exploited. Pests are a major problem threatening its cultivation.

Remarks: The origin of this important crop is still a subject of contention. It is believed to be of African origin, but the possibility of it being Asian cannot be discounted. There are only two species in this genus; the other, C. kerstingii. Harms, grows wild in West Africa and hence the assumption that the pigeon pea is probably of African origin. Some forms of this crop have their origin in India.

Description: Dense, evergreen, spinous shrub commonly found scrambling on other bushes or, rarely, standing by itself and sending out branches from the main bush. All parts exuding white latex on slight injury. SPINES: Straight, sometimes forked and up to 5 cm long. LEAVES: Broadly ovate to elliptic, glossy green, opposite and with a pointed apex. FLOWERS: Reddish pink outside, white inside as seen when they open. FRUITS: Round or ellipsoid, up to 26 mm in diameter, green, often tinged red or purple when unripe but turning dark purple (almost black) and glossy when ripe. Seeds few, dark brown, often compressed or undeveloped.

Ecology: Widespread in Kenya and much of Africa. Forest edges, bushland and thickets, especially on rocky hillsides. Common in rocky areas, on clay soils, especially black-cotton soils at valley bottoms and near seasonally flooded areas, 0-2,500 m. Rare in the coastal belt. Rainfall: 500-1,800 mm. Zones II-V.

Uses: FOOD: Both the unripe and ripe fruits are eaten whole (+++) (in the case of ripe fruits seeds may be discarded). The unripe fruits (green to purple) taste tart. Ripe fruits delicious-sweet and soft. Much liked by both children and adults. All fruits exude a milky latex. Flowers eaten (Luhya (Bukusu)).

MEDICINAL: The plant is among the most important sources of traditional medicine. Roots boiled and taken with soup to strengthen bones, for general fitness (Kamba, Meru, Pokot, Maasai) and (usually with other plants) for gonorrhoea (Maasai, Samburu, Kikuyu-Nyandarua). Boiled root extract drunk for chest pain (Kamba), indigestion, lower abdominal pains in pregnant mothers (Luo), polio symptoms (Samburu), headache and fever in children (Pokot). Decoction from boiled branches and leaves used for treating breast cancer, headache and chest pains (Nandi).

OTHER: Good goat fodder (+++). Good hedge plant (+++). Ripe fruits used as a dye by children. Silk-moth cocoons occasionally found on the plant.

COMMERCIAL: Fruits occasionally sold in markets.

Management: Seeds sown directly germinate easily. Saplings often grow under parent bushes and may also be used. Cultivated in several parts of the world for its fruit and as a hedge plant.

Status: Locally common. Rare in some parts (coastal areas) and Machakos, Makueni (partly due to over-exploitation for medicinal purposes).

Remarks: Carissa edulis is a variable species in Kenya. Variation is seen in the spines (some individual plants have almost all spines forked), fruits (while some are almost spherical, others have a slightly pointed base), leaves (some glabrous while others are hairy, and others conspicuously narrowed towards the apex). Some large fruit-bearing plants are found in parts of Ngong forest and in the Kitui highlands. The germplasm for some of these populations is threatened and hence the need to collect it. The taxonomy and herbarium collections of this species in Kenya (especially as it relates to C. bispinosa, with which it seems to share many features) needs to be clarified. Typically, the petals of C. edulis overlap to the left while those of C. bispinosa overlap to the right.

A related species, C. tetramera (Sad.) Stapf (Swahili: mtandamboo, Digo: mtandamboo, Giriama: mtandamboo, Chonyi: mtandamboo, Kambe: mtandamboo, Sanya: gurura) with forked spines, smaller fruit and slightly toothed leaf margins also has delicious edible fruits. Distribution: Kwale, Kilifi in coastal bushland and wooded grassland, 0-450 m. Propagation: Seed, direct sowing. Season: Flowers in December, January, February, May, June. Fruits in January, February, June, July, August in Nairobi, Kitui, Machakos, Embu.

Catha edulis Forssk.

Arabic: qat, khat Borana: chati, cati Chonyi: miraa Embu: miraa English: khat, Abyssinia tea, Arabian tea Giriama: miraa Kamba: mailyungi, miungi (plural) Kambe: miraa Kikuyu: muirungi, miirungi (plural) Kipsigis: tomoiyot Kisii: mairungi Maa: olmeraa Marakwet: tumayot Meru: muraa, miraa (plural) Okiek: tumayot Samburu: mamiraa Somali: qat, kat (pronounced chat) Swahili: miraa Teso: emairugi

Description: An evergreen shrub or large tree to 25 m with a dense crown. Trunk to 1 m in diameter. BARK: Grey-green or pale greyish brown. Young shoots green to red. LEAVES: Up to 12 cm long, narrowly elliptic with serrate margins, opposite, alternate on coppice shoots. Young leaves crimson brown, glossy, becoming yellow-green and leathery with age. FLOWERS: Small, white to creamy yellow in axillary cymes. FRUIT: A red-to-dark-brown, oblong, pendulous 3-valved capsule, up to 1 cm long. Seeds reddish brown with a small brown papery wing at the base.

Ecology: Found in south-western Arabia and Yemen and in many parts of Africa from Ethiopia to South Africa. Introduced in India and many other tropical countries. In Kenya, found, e.g. in the Nyambene mountains, Kyulu hills, south-western Mau forest, Cherangani forest, Mt Kenya, Turbo, Kakamega Forest, Mt Elgon. Cultivated in Nyambene and Meru. In the wild it is found in moist montane forests, evergreen forests and their margins, dry Olea and Juniperus forests, riverine forests and in thickets in Combretum wooded grassland. Along drainage lines and rocky hillsides, 1,200-2,400 m. Commonest around 2,000 m. Colluvial, stony or red soil. Rainfall: 800-1,800 mm. Commonest around 1,000 mm. Zones I-III.

Uses: Stimulant: Bark from fresh young shoots is peeled off and chewed as a stimulant, mainly by Somali and Meru and in towns (popular with long-distance heavy truck drivers as it is said to keep them awake). As one chews, a lump of khat (Somali: taksin) is gathered on one side of the mouth. Khat is usually chewed along with soft drinks, black spiced tea or chewing gum. The leaves are reportedly used to make a beverage like tea-called Abyssinia or Somali tea. Dried leaves may be smoked like tobacco. An important plant during wedding ceremonies (Boran, Somali).

MEDICINAL: Roots and bark boiled in tea or soup as a remedy for gonorrhoea (Kipsigis, Maasai).

CULTURAL/BELIEFS: Khat, tobacco and coffee taken as a gift to the girl's home during the first visit of the boy's parents as a sign of friendship between the two families (Boran). Said to form part of the bride price in marriage among people of Nyambene. Plant used in wedding ceremonies among the Boran and Somali.

OTHER: Building poles, fuelwood (++).

COMMERCIAL: Young shoots are sold in urban centres, especially to the Somali community. The khat trade is a flourishing multi-million shilling business in Kenya. Loads of it are harvested from the Nyambene highlands and air-freighted (mainly by chartered aircraft) from Nairobi to Somalia. It is also exported to the Middle East and often finds its way to Somali nationals in many parts of the world. Shoots are bound into small bundles which in turn are wrapped in banana leaves to protect the twigs from withering. In this condition khat can last for up to a week. In Kenya the banana leaves are hung outsides kiosks to indicate the presence of khat vendors. Despite its wide occurrence in other parts of Kenya, khat obtained from Nyambene District is of a superior quality. The Kangeta type with reddish purple bark is best and is often exported. Muringene and Maua types are poorer quality and are often mixed with the Kangeta type to increase their value. Up to six types have been reported in Ethiopia.

Management: Planting may be done vegetatively through cuttings. Twigs harvested for chewing are mainly obtained from coppiced plants.

Status: Generally uncommon in the wild. Large populations have, however, been reported in the Kyulu and Gwasi hills.

Remarks: Catha edulis, the only member of its genus, is an important drug plant in eastern Africa. Khat chewing is an important social activity among the Somali. Khat is usually provided to important visitors by the bride during wedding ceremonies. It is said to produce wakefulness and mental alertness by its stimulating effect on the nervous system. Thus it is used in situations requiring concentration.

The health, social and economic costs of khat chewing, however, outweigh the advantages. It induces thirst and therefore the user has to buy a lot of soft drinks. Khat is corrosive to the mouth wall. Chewing gum has recently gained popularity as it soothes the mouth besides absorbing stray khat particles. It is often a cause of constipation among chewers. It suppresses appetite and, when used for long periods, the alertness induced may lead to extreme fatigue and even stupor. Excess use of khat may induce symptoms of hallucination, intoxication or poisoning and, in extreme cases, insanity. Despite its short energy-boosting effect, prolonged use has been reported to cause emaciation and impotence. Khat chewing is addictive and often may impose a financial strain on the individual or family. The practice of chewing khat is condemned by non-users and is generally seen as unhealthy. There have been several attempts to ban the use of the drug by the authorities in Kenya and in some Islamic countries. The majority of khat users are found in the Islamic community.

Description: A trailing or climbing plant. Stems hairy, usually creeping extensively. LEAVES: With deep lobes, usually 3-5 lobes. Central lobe the largest. Tendrils usually divided into two, rarely simple. FLOWERS: Monoecious, petals yellow, joined below. FRUITS: Ellipsoid to almost round, usually 15-20 cm long, green with pale green longitudinal stripes and white juicy flesh. (Note: The form with dark green stripes on the surface and red-pink flesh is the one more commonly found in markets.)

Ecology: Tropical Africa, Asia and America. In Kenya grows, e.g. in southern Turkana along the Turkwel River and in the coastal region. Cultivated land, abandoned cultivation, grassland, flood plains, 0-1,400 m. Common on sandy soils. Zones II-VII (riverine).

Uses: FOOD: The fruit is peeled and the flesh eaten raw or boiled. It can also be peeled, seeds removed and chopped into small pieces which may be eaten raw or cooked with pumpkin leaves or those of Lycium europaeum L. (Turkana: ekereru, Daasanach: il-maarach). Seeds may be sun-dried, ground and the resulting meal mixed with sorghum flour and made into a porridge, atap (Turkana). In other parts of Africa, seeds may be roasted and eaten. Leaves are also reported to be used as a leafy vegatable.

OTHER: Children make toy wheels from the fruits (Makueni).

COMMERCIAL: Local form sold in Turkana. Commercially cultivated form common in most markets in large towns.

Season: Fruits in July in southern Turkana.

Status: Common in cultivation (Turkana). Rare elsewhere.

Remarks: The local form of the watermelon is among the earliest cultivated food plants of the Ng'ikebootok in southern Turkana who believe that it came with elephant dung. Both the immature and mature fruits are eaten raw. The mature ones are sweeter.

Description: An erect herb to 1.3 m high (usually 0.5-1.0 m). Stems hairy, rather oily. LEAVES: On long stalks, usually divided into 3, 5 and 7 leaflets, to 7 cm long. FLOWERS: White or pink borne on a long much-branched inflorescence. FRUIT: A long-stalked capsule splitting to release small rough, greyish black seeds.

Ecology: Widely distributed in most of Africa, tropical Asia and America and all over Kenya as a weed of cultivation and disturbed areas, 0-2,400 m. Common in abandoned homesteads, especially animal enclosures. Soils: Fertile soils with a lot of organic matter. Zones I-VI.

Uses: FOOD: Leaves (often with flowers) widely used as a vegetable in Kenya, especially in the western and coastal regions (+++), (Luo, Luhya, Kisii, Teso, Kipsigis, Nandi, Giriama). Not a traditional vegetable of the Central Bantu, however. By themselves leaves are bitter. Leaves are boiled, butter added and eaten along with ugali made from finger millet flour. This is served to important visitors such as in-laws as a sign of respect (Luo). Usually cooked with other vegetables such as cowpeas, amaranth (Luhya, Pokot, Luo) and Solanum nigrum (Pokot). In western Kenya, milk is added and preferably left overnight in a pot. This reduces the bitterness. Leaves mixed with those of kandhira (Brassica carinata) are boiled, made into lumps, dried in the sun and stored in a clay pot (agulu) as a dry-season food (Luo). This may be eaten with apoth (Asystasia mysorensis) as mboga. Among the Kisii, it is almost mandatory for women to use this before and after childbirth, circumcised boys must eat it and it is served to important visitors.

MEDICINAL: Root infusion used for chest pain (Makueni); vegetable a cure for constipation (Luo). Water obtained after boiling leaves is used to treat diarrhoea (Luo). Leaves are pounded with a little water and the extract drunk as a treatment for chira (a condition with symptoms like those of AIDS, but associated with a curse or punishment from the spirits). Patient also bathes with this.

COMMERCIAL: Vegetable sold in the major towns, especially in Coast, Nairobi, Nyanza, Rift Valley and Western Provinces.

Management: Grown from seeds. Planted either in lines or by broadcasting. Cultivated on a small scale by farmers, especially the elderly in western parts of Kenya. Outside Kenya commonly cultivated for seed oil.

Status: Common.

Remarks: Because of the bitterness of the leaves, some people prefer not to use salt. The Mijikenda believe that use of salt may lead to the disappearance of the plant from cropland. The synonym Gynandropsis gynandra is the name used at the East African Herbarium. The related species Cleome monophylla L. (Somali: aiyo) is widespread in Africa and common as a weed in cultivation. C. allamanii Chiov. (Somali: liimo danyeer) and C. hirta (Clotzsch) Oliv. (Somali: garah lahgurare) are also used as a vegetable but to a lesser extent. Their leaves are smaller. Among the Luo, dek is often used as a general term for a leafy vegetable.

Male flowers usually solitary or paired, female flowers solitary. FRUITS: Ellipsoid, to 7 cm long by 4 cm wide, rounded at both ends, green, ripening to bright red from the bottom upwards. Ripe fruits soft and easily detached from the plant.

Ecology: Tropical Asia, tropical Australia, Arabia, Fiji, introduced to West Indies and tropical South America. In Africa from Senegal east to Somalia. In Kenya, e.g. in Moyale, Turkwel Valley (riverine bushed grassland), Kisumu, and Kibarani in Kilifi District. Grows in dry Acacia bushland and riverine bushland. Commonly found climbing on bushes and hedges. Zones III-V.

Uses: FOOD: The soft juicy, bright red fruit are eaten raw (+) (Kamba, Turkana, Pokot). Ripe fruit are beaten into a solution, boiled in water, flour added and made into stiff porridge (Turkana). The fruits are dried, ground into flour and mixed with cereal flour (Turkana). Young leaves occasionally used as a vegetable (Luo (Siaya), Mbeere, Kikuyu, Pokot (Nginyang)), mashed and mixed with maize and pulses (Kikuyu, Mbeere).

MEDICINAL: Leaves mixed with ghee are used as medicine for hima (pain on the left side of the abdomen and lightening of the skin) in children. Medicine is applied externally (Luo).

OTHER: Seeds chewed (Daasanach). Fodder for camels and all livestock (+). Fruits eaten by birds.

Season: Flowers in January-February (Marsabit), March-April (Wajir, Isiolo, Turkana), December (Homa Bay), September (Taita), November (Kitui, Samburu). Fruits in March (Samburu, Kajiado, Kitui), October (Mombasa), June (Kilifi).

Status: Common.

Remarks: In Asia the fruits are occasionally candied and sold in local markets. This species resembles C. trilobata (Cogn.) C. Jeffrey (Kikuyu: kigerema, Mbeere: kirigirigi, Samburu: nkaisiruaruai). Stems slender but strong. Leaves usually 3-5 lobed and very rough above (usually more so than in C. grandis) and softly hairy below. Fruits ellipsoid, often with a narrow end, bright red with longitudinal stripes of light green or yellow. Very common around Nairobi. Found in the central part of the country. Rift Valley and coastal area and in northern Tanzania but not known anywhere else. The leaves are used as a vegetable (Mbeere, Meru, Kikuyu). C. adoensis (A. Rich.) Cogn. (Kamba: kyambatwa, kimoe, Luhya (Bukusu): nandemu, Luhya: obutsiba). Grows in most parts of Kenya, e.g. in Kitui, Kitale, Thika, Karura forest. Also in southern Africa. A creeping or climbing plant with deeply lobed leaves. Fruit pale green with dark green interrupted longitudinal lines, ripening to orange-red. Altitude 0-2,400 m, especially in bushland, grassland and at roadsides. Fruits are edible. Normally associated with snakes. Liked by birds.

Coffea arabica L.

Rubiaceae

Borana: bun English: arabian coffee, arabica coffee, coffee Kamba: kaawa Kikuyu: kahua Kipsigis: kawek, kahawek Kisii: ekawa, ekahawa Luhya (Bukusu): ekawa Luhya (Tachoni): kahawa Luo: kawa Meru: kahuwa Mijikenda: kahawa Somali: bun Swahili: kahawa

Description: Shrub or small tree up to 6 m high, but kept below 3 m in cultivation. Leaves elliptic, flowers white and axillary. Fruit a 2-seeded drupe, ellipsoid, to 2 cm, green, turning red to dark red on ripening.

Ecology: Wild populations of coffee are found in southern Ethiopia and in northern Kenya on Mt Marsabit and possibly Mt Kulal in highland forests, 1,300-1,500 m. Coffee is cultivated throughout the tropics and most of Africa. In Kenya it is grown throughout the country at medium altitude (1,300-2,200 m) and rainfall (700-1,200 mm). Does well in deep red clay-loam soils. Zones III-IV.

Uses: This is the well-known coffee plant grown for its seeds which are the source of household coffee, a stimulating beverage. Processing involves separating the fruit pulp from the seeds. In homes this may be done by squeezing the ripe fruits in water. The cream seeds are washed and dried for a few days then pounded in a mortar to remove the seed wall. Seeds are then roasted and pounded or ground. Bulk processing in rural coffee factories involves removing the fruit wall, grading, fermenting, air drying and packing. Roasting is a specialized process done at a central factory. In Ethiopia, coffee drinking is an important social event. Members of a neighbourhood may meet every morning to drink coffee (Guragae area, central Ethiopia). It is served in special pots and cups. Members meet at the house whose owner's turn it is to prepare the coffee.

Management: Easily grown from seeds in nurseries from where it is transplanted to farms.

Other: Pruned branches used as firewood. "Husks" from factories are used as manure.

Cultural/beliefs: Coffee, tobacco and khat are taken as gifts to a girl's home during the first visit of the boy's parents as a sign of a developing friendship between the two families (Boran). Coffee is one of the plant materials offered under fig trees during some cultural ceremonies (Boran).

Remarks: Arabica coffee is native to the Kaffa region (whence the name coffee is derived but now falling under Oromia Federal State) of southern Ethiopia.

Several other species of coffee are cultivated. The best known of these is Coffea canephora (syn: C. robusta), (English: robusta coffee). This is said to have the highest content of caffeine. Others are C. liberica (English: Liberian coffee) and C. stenophylla (English: Sierra Leone coffee, highland coffee), both of West Africa. At least five other species of Coffea are found wild in Kenya but are of no commercial importance. Coffee is an important export crop in Kenya, ranking second after tea in foreign currency earnings.

Description: A prostrate or erect (when young) herbaceous plant with soft stem. LEAVES: Alternate, lanceolate to almost linear with bases clasping the stem. FLOWERS: Yellow, occasionally white. Leaf blade ovate, up to 10 cm long by 5 cm wide.

Ecology: A common Commelina in tropical Africa and in Kenya. Rare in northern Kenya and the coastal region. Found in cultivated and disturbed areas, open grassland, bushed grassland and under trees in woodland.

Uses: FOOD: Widely eaten as a vegetable (Luhya, Luo, Kamba, Teso, Mbeere) (++). An important vegetable just after the onset of the rainy season before cultivated vegetables are available; it is soft and therefore mixed with other types of leafy vegetable.

FOOD/MEDICINAL: Stalks pounded, boiled and milk added for children's colds and coughs (Samburu); fluid from spathes is applied locally for eye diseases.

OTHER: Fodder (+++) for all livestock; the plant sprouts earlier than other plants and is therefore useful, especially after a prolonged dry season. Said to quench thirst in animals.

Management: Propagated vegetatively from rhizomes.

Status: Common.

Description: Spreading, much-branched bush, shrub or tree to 6 m high (normally 3-5 m). BARK: Yellow to ash grey, smooth, flaking. LEAVES: Ovate to almost round, very rough above, greenish grey. FLOWERS: Cream, turning brown on drying. FRUIT: Yellow or orange, oval, up to 2 cm across.

Ecology: Grows in India, Sri Lanka and in Africa from Sudan south to South Africa. Widely distributed all over Kenya in bushland, 0-2,200 m. Common in valley bottoms and along watercourses. Often on rocky areas and red clay soil. Zones I-VI.

Uses: FOOD: Mucilaginous pulp of fruit edible (+). Fruit coat is normally removed, the pulp (with seed) is sucked and the seed discarded. The pulp is sweet but gummy.

MEDICINAL: Roots boiled and the extract taken for vomiting and malaria, especially by children. Leaf extract given to animals and people to remove retained placenta (Tharaka).

OTHER: Fuelwood, shade, good charcoal, handles, wood carving (Kamba), beehive hooks (Kamba, Tharaka). Rough leaves are used as sandpaper to polish wooden shafts of spears (Maasai, Pokot). Camel and goat fodder. Stems made into clubs (Luo) and thinner ones into arrow shafts (Maasai, Narok). CULTURAL/BELIEFS: Used in blessings (Maasai, Samburu, Pokot). Used in rituals (Luo). The Maasai believe that if a livestock keeper carries an oseki stick his cattle will not suffer from certain diseases. Believed to be a peace-engendering plant (Maasai). To stop a fight or to prevent oneself from being attacked, a stick from this plant is placed between the opposing parties. The aggression should stop immediately. Whoever disregards this warning may be punished heavily. Bad luck may also befall him and it may mean death of one or more members of the family. It is therefore enough warning to say "elua eseki", meaning "I separate you with eseki".

Season: Flowers in April-May (Kajiado, Samburu), October-November (Taita, West Pokot, Nairobi, Meru). Fruits in February-March (Kajiado, Samburu), April-May (Kwale, Kisii); June-July (Machakos, Kitui, Meru, Isiolo), August (Isiolo, Baringo). Timing mainly depends on rains.

Management: Propagated by seeds sown directly and without pre-treatment.

Status: Common.

Uses: FOOD: Ripe fruits eaten raw (+++). The sweet mucilaginous pulp may be eaten fresh. Fruit cover and seeds are discarded. Large quantities of the fruits are gathered, pounded to a sticky mass, sun-dried and stored in a wooden container, eburr (Turkana). Whenever it is needed, water is added to soften it, then served. The fruit pulp is sometimes used for brewing a local beer. The fresh fruits are squeezed in water to dissolve the pulp. This is mixed with tamarind (Tamarindus indica) juice and fermented. Fresh juice may also be drunk (Turkana). A clear gum produced by the tree is edible.

OTHER: Stems are widely used as poles in hut construction (+++) (Turkana, Pokot, Boran, Somali, Gabra) and for erecting bird-scaring platforms in sorghum fields (Turkana). In many cases these may root, hence becoming a near-by source of food. Fodder (+++) for goats, camels, sheep and cattle. Stems are made into walking sticks, wooden spoons, stirrers. Stems used for smoking gourds (Maasai).

CULTURAL/BELIEFS: Branches are spread where the house of a newly married couple is to be built, branches are put above the house during almadho and soriyo ceremonies (Samburu). Sticks used in settling battles in the absence of C. monoica, oseki (Maasai). Widely used in rituals (Gabra, Samburu. Maasai, Boran).

Description: A trailing or climbing plant. Stems with tendrils, angled and with prickly hairs. LEAVES: Ovate or shallowly 3-lobed, coarsely hairy, light green, up to 10 cm long. FLOWERS: Yellow. FRUITS: Oval with numerous protrusions, light green, turning yellow on ripening.

Ecology: North-eastern tropical Africa in bushland, grassland, cultivated land and in disturbed areas climbing on bushes and on hedges. Common at river banks on alluvial and sandy soils but also found in clay soils, 425-1,800 m. Zones IV-VII (riverine).

Uses: FOOD: Young leaves from young plants (Turkana) or young shoots of older plants are used as a vegetable (++) (Kamba, Turkana, Pokot). Leaves are occasionally used in mashed food (Makueni).

MEDICINAL: Roots and leaves crushed and put on cuts. Juice from fruits used to rub on swollen neck glands (Pokot). Fruit juice is made into a solution (Pokot, Somali) or boiled (Luo, Homa Bay) and taken as an emetic or purgative (Turkana). Solution is usually given as an antidote after poisoning. Milk is served immediately after vomiting (Pokot, Nginyang).

OTHER: Goat and camel fodder. Fruit liked by donkeys, pulp eaten by squirrels (Makueni), but said to be poisonous to man.

Season: Leaves available 2 weeks after the start of the rainy season and fruits 2 months later.

Management: Plant grows easily from seeds.

Status: Common.

Remarks: The fruits of several Cucumis species are used as food. These include C. prophetarum L., a prostrate herb from a perennial rootstock, with rough, narrow-lobed leaves and yellow flowers. Fruit egg-sized, pale green with dark green lines and soft bristles, ripening to a yellow colour. (Turkana: ekolese, Samburu: ntuyu, Pokot: ariapongos, Maa: ilporbol lo ntare). Ecology: India west through the Middle East to Africa. Widely distributed in the drier parts of Kenya. Not recorded in Nyanza and western Kenya. Found in dry bushland and woodland. Processed fruits are used as food (Turkana). Fruits are goat and sheep fodder. Two subspecies are recognized: ssp. dissectus (Naud.) Jeffrey, found in north-eastern Africa, the Democratic Republic of Congo (Zaire), Uganda, Tanzania and most parts of Kenya; ssp. prophetarum found from Senegal east to India and the northern parts of Kenya. Ripe fruits are clear yellow.

Another member worth mentioning in this genus is Cucumis metuliferus Naud. (English: spiny cucumber, horned cucumber). This is a climbing herb with hairy stems and solitary unbranched tendrils. LEAVES: Heart-shaped, hairy with long petioles. FLOWERS: Male and female flowers are separate on the same plant. FRUITS: Up to 12 cm long by 6 cm wide. Dark green with striations of white dots and covered with scattered spiny processes to 1.2 cm long, with a horny tip. The fruit turns orange to bright red on ripening. It is found in Acacia bushland (in miombo woodland in southern Africa) and roadside bushes mainly in red alluvial or loamy soils at an altitude of 800-1,300 m. The species is found wild in northern Kenya. Collections have been made in Sigor (West Pokot) and Mandera. It is widely distributed in the rest of Africa but cultivated for commercial purposes in southern Africa. The mature unripe or ripe fruits are eaten raw. The horny part of the spiny processes is cut off and the fruit split to eat the seed-filled white to translucent pulp. Fruit may also be peeled. This fruit has the taste of a cucumber (Cucumis sativus). Its use as a food has not yet been reported in Kenya. The fruit is common in markets in southern Africa and is also exported to Europe and America. The leaves may also be used as a vegetable.

The ripe fruit has a striking orange-red colour and so the plant may also be grown as an ornamental. Fruits last long in cool weather.

Cucurbita ficifolia Bouché (English: Fig-leafed gourd, malabar gourd, Kikuyu: kahurura, kanyuria) is another extensive creeper or climber. Cultivated in the central highlands, especially by the Kikuyu. Leaves used in the preparation of irio, a mixture of maize, pulses and often green bananas and/or Irish potatoes. It usually germinates spontaneously in cultivated land.

Also commonly grown for their fruit and leaves are the pumpkins (Borana: bododa, Kamba: ulenge, ilenge (fruit), Kikuyu: marenge, Kisii: risosa, Embu: irenge, marenge, Luhya (Bukusu): lisiebebe, liondo (fruit), Meru: marenge, malenge (Nyambene), Turkana: ekaideit) Cucurbita moschata Duch. ex Lam. and Cucurbita maxima Duch. Ex Lam. C. moschata has distinctly lobed (divided) leaves, while those of C. maxima only have a wavy margin. Both have yellow flowers. Leaves and young shoots are used as vegetables.

Description: Erect herb usually 0.7-1.3 m high with numerous straight thin branches, some arising from just above ground level. LEAVES: Usually narrow and up to 6 cm long, apex pointed. FLOWERS: Small, pink to white, borne on a long slender inflorescence.

Ecology: Found in Uganda, Tanzania, Sudan, Ethiopia, Somalia, Socotra and in Asia (ssp. muricata). All over Kenya in dry bushland, grassland, forest edges and hillsides. Most common in dry low-lying areas in grassland, flood plains, cultivated land and disturbed areas, especially towns, 0-1,500 m. Commonest below 1,000 m. Varied soils: alluvial in flood plains, sandy loam to red clay. Mainly in Zones V-VI, but var. patentipilosa in Zones III-IV.

- var. trinervis the commonest of the three found all over Kenya

- var. macroptera C. C. Townsend almost as widely distributed and closely resembling var. trinervis

- var. patentipilosa has ovate leaves with prominent veins underneath and a short spike. It is found at the coast and is much used by the Giriama. This last variety has large leaves and great potential for domestication.

Dioscorea bulbifera L.

Dioscoreaceae

English: potato yam, air potato Giriama: mutokera Luhya (Bukusu): liliakhunyu Luhya: litugu, lirungu Luhya (Maragoli): litugu, liruku Luo: oruka, oroko

Description: A twining dioecious plant. Underground tubers elongate or nearly round and irregular, occasionally absent. Aerial tubers (bulbils) up to 7 cm in diameter, brown, rounded or angular. LEAVES: Alternate with a long petiole, heart-shaped, narrowing towards the apex. FLOWERS: Pink-white, borne on long inflorescences arising from the leaf axils. Male up to 4 per axil and up to 10 cm long. Female up to 3 per axil and up to 30 cm long. FRUIT: A dry capsule to 2 cm long.

Ecology: Tropical Africa (including West Africa), Asia, Pacific islands. Cultivated in western Kenya. High-rainfall lowland and mid-altitude rain forest, wet woodland, swamp and stream edges. Zones I-III.

Uses: FOOD: Aerial tubers roasted or boiled like sweet potatoes (Luhya, Bukusu). Often soaked for about two days in cold water to dissolve out poisonous compounds.

FOOD/MEDICINAL: Boiled tubers peeled and given to children as a cure for measles. Often maintained traditionally in gardens for this purpose (Luhya).

Management: Grown from the mature bulbils. New shoots may also grow from the rootstock. In poor soils it should be planted with manure if possible.

Status: Very rare, probably entirely absent in the wild. The cultivation of this crop in Kenya has declined considerably in recent years.

Remarks: Two varieties are distinguished in Kenya:

· the cultivated var. anthropophagorum (A. Chev.) Summerh. with reduced or absent underground tubers and angular edible aerial tubers

· the wild var. bulbifera has no underground tuber but has rounded aerial tubers; it is reportedly poisonous.

· var. sativa with edible tubers is an Indian variety.

The yams belong to the family Dioscoreaceae, a group of plants which, like the grasses, have one cotyledon (monocotyledons). There are about 600 species in the genus Dioscorea distributed over the tropical and subtropical parts of the world. They are generally dioecious twining climbers, often prickly and arising from a tuberous rootstock. Yams are known for their tubers which may be underground or up on the stem (aerial). The yam tuber is the storage organ for the plant and is the edible part. Many of the species, however, do not have edible tubers.

Yams are cultivated throughout the tropics, especially in South-East Asia, Central and West Africa and in South America. In West Africa they are an integral part of the culture. D. bulbifera, a native species in East Africa and a traditional crop of the Luhya, has long been cultivated in Africa and Asia. Some other species of edible yams cultivated in East Africa include the West African yams (D. cayenensis or yellow Guinea yam) and they are cultivated in Uganda and probably in western Kenya too. D. alata (white yam, originally from India) is also cultivated in Uganda and Tanzania but reportedly not yet in Kenya.

Dioscorea dumetorum (Kunth) Pax

Dioscoreaceae

Boni: digi Giriama: mariga Maa: ol-oibare bare Swahili: maringa, kiazi kikuu, vigongo, kikwa, ndiga, mariga Taita: mako

Description: A twining prickly dioecious plant. Underground tubers lobed, often intertwined among roots. LEAVES: Long-stalked, divided into three leaflets, rather rough above, light green and softly hairy below. FLOWERS: Inflorescences long and pendulous, to 20 cm, often branched, dirty white, woolly. FRUIT: A winged capsule to 3 cm long.

Ecology: Grows from Ethiopia and Somalia west to Senegal and south to South Africa. Found in Kenya in the coastal region and in adjoining areas, 0-1,650 m. Cultivated to a small extent outside Kenya. In the wild at edges of low evergreen forests, coastal bushland and Brachystegia woodland. Commonly found on deep sandy soils. Zones II-V.

Uses: FOOD: Tubers eaten like potatoes (++), and used as a famine food (Boni (Tana River), Giriama). Tuber roasted like the cultivated yam. A most important wild tuber but requiring careful preparation as it may be poisonous. Tubers are normally peeled, soaked and washed before cooking. This eliminates the poisonous compounds normally concentrated in the latex. In southern Sudan the tubers are boiled and soaked for three days before being eaten. Tubers are peeled, sun-dried, ground into flour and made into stiff porridge, sima (Digo).

MEDICINAL: Dried and ground roots mixed with water are used to cure bilharzia.

Remarks: In Tanzania the root is reported to have caused vomiting followed by death when eaten raw.

Dioscorea minutiflora Engl.

Dioscoreaceae

Embu: gikwa, ikwa (plural) (tuber) Kamba: kikwa Kikuyu: gikwa Kisii: chinduma (plural), enduruma (singular) Luhya (Bukusu): litolotolo Luhya (Maragoli): kihama Luhya (Tachoni): litolotolo (plural) Meru: rukwa, gikwa (tuber), Sabaot: musapchet, mucukwet Swahili: kiazi-kikuu, viazi-vikuu (plural)

Description: A prickly twining perennial, dioecious plant. Stems slender, prickly, arising from a tuberous root. Tubers reddish brown, up to 40 cm long with several finger-like projections. Found 20-50 cm below the soil surface. LEAVES: Usually opposite, often heart-shaped with a pointed apex. FLOWERS: Male numerous, borne on a cluster of up to 10 short stalks on either side of the leaf node. Female borne in pairs on flower stalks which are longer than those of the male, up to 15 cm or more and resembling "hair pieces". The two flower stalks are opposite each other at the leaf node. FRUITS: Winged, rare.

Ecology: Grows wild from Uganda west to Senegal and south to Angola, but not in Kenya. Cultivated in Kenya especially by the Kikuyu, Embu, Meru (previously by the Kamba) and by some communities in Tanzania and Uganda. In the wild it is common at the edges of tropical forest where it twines to great heights on other plants. In cultivation the plant is found in humid areas with deep, well-drained soils. Mostly does well in deep fertile red soils. Common at 1,500-2,400 m in areas with more than 700 mm rainfall. Zones II-IV.

Uses: FOOD: The tubers are eaten either roasted, boiled or fried. Tubers for roasting require no peeling and are the tastiest. Yams may be fried with other types of tubers like Irish potato. D. minutiflora has a dry consistency with an appealing taste. Tubers are much relished by old people. Damaged or bruised tubers do not keep for long.

COMMERCIAL: Tubers are occasionally sold in Nairobi and Central Province. They are generally more expensive than other types of tubers.

Management: Many types of yams are propagated vegetatively. In Central Province, among the Kikuyu, D. minutiflora is propagated by use of the hard, much-branched stem base (ihindi, meaning bone), from which the tubers arise. Portions of the stem base are chopped off. The pieces may keep for a month or more. Preferably the soil should be mixed with manure. Planted pieces take 3-5 weeks before sprouting. As the stems are weak they should be supported by strong, tall stakes to give the plant more space for climbing and to enable more light to reach the leaves. Better still, the yam can be planted near an existing large tree on which it can twine. Traditionally the Kikuyu, Embu and Meru plant D. minutiflora along with cuttings of Commiphora eminii ssp. zimmermanii (Kikuyu: mukungugu, Chuka: mutungururi, Embu: mukugugu) for support, and hence the Kikuyu saying, "They are as friendly as the gikwa and mukungugu". Where the soil is not deep or loose, artificial mounds may be created.

Growth is quite fast (up to 1 m a month) and tubers may be harvested after 2-3 years. One plant at the Nairobi Museum that had not been disturbed for almost 20 years gave more than a 60-kg sack of yams!

The yam can be intercropped with other common crops like maize, beans and Irish potatoes. They can also be planted just outside crop land where they will not inconvenience other activities. They should be grown on deep-rooted trees to avoid competition.

Remarks: The most commonly used yam in Kenya; at one time widely used by the Central Bantu. But its use as food has declined rapidly in recent decades. It is now a rare crop, almost invariably maintained by elderly women as a matter of tradition in their small shambas.

Also referred to as "yam" in Kenya is Colocasia esculenta (L.) Schott (Araceae), syn. C. antiquorum Schott (English: cocoyam, taro, Swahili: nduma, Kikuyu: nduma, matuma (leaves), Kisii: enduruma (singular), chinduma (plural), Kamba: nduma, Embu: nduma, ituma (singular), Luhya (Bukusu): litolotolo, Mbeere: nduma, Meru: nduma, matuma, ituma (singular)). This is the root crop erroneously referred to as arrow root in Kenya. The starchy corms, which may have a black or greyish cover, are much liked, especially for breakfast. The leaves are also used as a leafy vegetable as a side dish (mboga) and for mashing with traditional food (kienyeji, Kikuyu, Kamba). Cocoyams are native to Asia and the Pacific islands. They are propagated vegetatively by planting the top of the corms (the stem base) in valley bottoms, along streams and where waste water collects. C. antiquorum was until recently treated as a distinct species but now it is considered a variety of C. esculenta. Var. antiquorum (Schott) Hubb. & Rehder is the commonest variety in Kenya; var. esculenta is distinguished by the presence of numerous smaller corms in addition to the main one. The earliest forms to be cultivated by the central Bantu had small, less tasty corms that left an itchy sensation in the throat (Kikuyu: nduma-ya-mwanake) after eating them. Nowadays, these are rare as they are rapidly being replaced by the larger tastier cultivars.

Description: A grass usually 0.5-1 m high. FLOWERS: Head dirty green and branched into 5-7 spikes (fingers) usually 5-10 cm long. FRUITS: Grain usually reddish brown, dark brown or occasionally cream.

Ecology: In Africa found in cultivation from Nigeria east to Eritrea and south to South Africa and Namibia. Northeastern Africa is considered the centre of origin of this crop.

A traditional crop of many communities in Kenya, but nowadays grown to a relatively smaller extent than before. Still a major crop among the Kuria, Ilchamus, West Pokot District, Tugen and Marakwet, 0-2,400 m. Requires fertile soils and 650-1,000 mm well-distributed rainfall. Zones II-IV.

Uses: FOOD: The grain is normally made into flour used for the preparation of uji (porridge) and ugali (stiff porridge). It is often mixed with sorghum or maize in these preparations. Sour milk and melted butter are added to ugali made from finger millet and this is wrapped in new banana leaves and eaten by warriors (Luo). Flour and grain are also used in local beer brewing, especially among the Luo, Kuria and Luhya. Among the Luo, the seeds are germinated and dried (thowi), ground and put in water for 4-7 days to ferment. Fresh flour is put in water for a day or two and fried in balls (mbare). The two are mixed and left for about three days to ferment. The resulting brew is drunk through long hollow sticks called oseke tipped with a filter. Finger millet has been cultivated in Kenya since ancient times and is a traditional food for many communities, especially Keiyo, Marakwet, West Pokot, Tugen, Giriama, Taveta, Teso, Luo, Luhya, Kisii, Kikuyu, Ilchamus, Embu, Taita, Kuria, Kamba. Its use as a food is closely integrated in the traditional customs of many communities.

COMMERCIAL: Grain and flour are sold throughout the country. Now common in major food stores in towns.

Management: Traditionally sown by broadcasting. It can also be sown in lines, especially when intercropped. Finger millet requires fertile soil and is normally associated with shifting cultivation. It is less susceptible to bird attack than bulrush millet. Harvesting: Individual heads are cut and spread out to dry in the sun. These are threshed, winnowed and the grain stored. This grain can keep for over ten years. This ability to keep for a long time made it an important famine food in the olden days.

Remarks: Like many of the traditional grains, the cultivation and utilization of finger millet has declined in recent years. This may be attributed to:

· Low yields compared to maize. The latter has thus superseded finger millet where it used to be grown.

· Tedious traditional methods of preparing the grain.

· Not many people are used to eating it nowadays (mainly due to neglect). This has reduced demand and the market price for the grain. More recently, however, packaging and availability of the flour in shops and supermarkets has helped boost consumption in towns.

Eragrostis tef (Zucc.) Trotter

Gramineae (Poaceae)

Borana: tafi, thafi English: teff Gabra: tafi

Description: A small grass usually to 0.6 m high. FLOWERS: Inflorescence white or brown. FRUITS: Seeds small, ovoid, about 0.5-1.0 mm long, brown or white (cream) in colour.

Ecology: Teff is an almost exclusively Ethiopian cereal but in Kenya it is popular among the Boran groups and people of Ethiopian origin. Grows wild and also widely cultivated in the Ethiopian highlands. Occasionally cultivated on a small scale in the Marsabit and Moyale highlands, 1,000-2,500 m (in Kenya). Rainfall: 650-900 mm. Introduced further south for experimental purposes in agricultural research stations (Katumani, Kitale, Muguga). Also introduced in Lesotho and South Africa as a fodder crop.

Uses: FOOD: A traditional grain crop of the Oromo groups of people including the Boran. Grain is ground to flour (traditionally, stones are used for grinding) which may be used in the preparation of an Ethiopian bread (known as injera in Ethiopia and anjera by the Boran), porridge and cakes. Injera is made by fermenting dough for about three days. A handful of the fermented dough is put in hot water which is then used to prepare more dough. This is poured on a large hot plate up to 60 cm across and a pancake made. Anjera (Boran) is served with meat stew (often spiced) or vegetables on large, shallow plates. The grain may be eaten alone. There is a cream type of grain and a brown type which has a similar but slightly bitter taste.

COMMERCIAL: Grain and flour are traded locally in northern Kenya. The cream type is tastier and more valued than the brown. The grain is sold in the purely brown or purely cream forms but mixtures with varying proportions of the two are more common, the price charged being a reflection of the ratio of the two.

Management: In Ethiopia, land is ploughed up to three times between April and August. Seeds are usually sown by broadcasting but may also be sown in lines. Harvesting is done in November-December. Weeding is usually done once. The two cultivars (cream and brown) are hard to separate once mixed. For this reason the grain is often seen in varying mixtures of the brown and the cream seeds. Harvesting: Traditionally the grain is cut from the field and spread in a clean, usually round, clearing. The grain is separated from the heads on the stalks by driving oxen several times over the pile. Forked sticks are used to remove the stalks. The seeds are separated from the chaff by winnowing (usually with a wooden spade).

In Ethiopia teff is grown only once in a year. Heavy rain, especially when the grain has formed, spoils the teff. This, together with frequent droughts, has been a main cause of the famines in Ethiopia in recent years.

Remarks: Teff is an old and locally important crop of the Ethiopian communities but little known outside the country. Injera is the staple food of some communities, especially in north-western, central and southern Ethiopia. It is a common food in Ethiopian restaurants throughout the world.

Eriosema shirense Bak. f.

Papilionaceae (Fabaceae)

Kamba: ng'athu Maa: enkaikuinyoi (Loita)

Description: Small erect herb to 30 cm high, normally single stemmed (remains of older stem may be present) and arising from a chain of tubers formed from enlargements at intervals along the taproot. Tubers one to several, surface brown or grey, white inside, usually found 10-25 cm below the soil surface. LEAVES: Long, hairy. FLOWERS: Yellow with dark purple lines. FRUIT: A broad hairy dark-brown pod to 1.5 cm, shrivelling after dehiscing.

Ecology: Apart from Kenya, it also grows in Uganda, Tanzania, Malawi, Cameroon, Rwanda, Ethiopia, Zimbabwe and Angola. In Kenya, e.g. in the Kitui hills, Loita hills, Thui Hill, northern Kyulu and Kilungu hills. Bushed grassland, especially on rocky hillsides, 1,400-2,200 m. Mainly in Zones in-IV.

Uses: FOOD: Tubers peeled and eaten (++) (Kamba, Maasai, Kipsigis). Very tasty and said to always leave one longing for more. They are, however, small. Plant often found in rocky areas and hence may be difficult to dig up. Tubers spoiled by rain. Also eaten in Tanzania and Malawi.

Season: Tubers in December-January and June-July in Thika, Machakos and Makueni.

Management: Propagated by seeds. Very specific to certain soil types.

Status: May be locally common though generally rare. Now threatened due to habitat destruction.

Description: Annual herb to 1 m high, often less. LEAVES: Slightly hairy, lobed or wavy. FLOWERS: Yellow to cream, borne on long slender shoots. FRUIT: A long slender capsule to 5 cm. Seeds brown, small, round. Fresh roots smell of mashed Irish potatoes.

Ecology: Grows from Arabia, Somalia, Ethiopia and Sudan through eastern and southern Africa south to Botswana and Namibia. Introduced in many other parts of Africa. In Kenya, e.g. on Mt Elgon and in the highlands of central and western Kenya in upland grassland, disturbed places in forests and cultivated land, 0-2,500 m. Most common at 1,500-2,000 m. Zones II-IV.

Uses: FOOD: Leaves eaten as a vegetable (++) (Kikuyu, Pokot, Kamba, Kipsigis, Maasai, Narok).

Status: Locally very common, e.g. in Nairobi.

Remarks: Many Kenyan species of the family Cruciferae (cabbage family) are introduced. As they are often weedy, they tend to escape easily from cultivation. E. arabicum has been introduced as a weed in many regions of Africa and is probably introduced in Kenya too. Other notable genera with members providing leafy vegetables are Brassica and Rorippa. R. nasturtium-aquaticum (L.) Hayek (English: water cress, Kikuyu: mararia) is used as a vegetable by the Kikuyu. It is a trailing herb with pinnate leaves, white flowers and short capsules. Stems root at the nodes. Found in the highlands east and west of the Rift Valley and Nairobi area at 1,500-2,750 m, mainly along streams.

Season: Fruits in January-March in Tana River, Marsabit and southern Turkana and in April in Machakos, Makueni, Narok and Taita.

Status: Occasional.

Remarks: Most fig species have edible fruits. They were important famine foods in the past but their use has declined a great deal, especially in the agricultural areas. A closely related species is F. sur Forssk. (syn. F. capensis Thunb.) (English: Cape fig, Somali: berde, Luo: bongu) with greyish bark and figs that are borne in clusters on special branched stalks arising directly from the trunk. It is found in West Pokot, Makueni and most parts of Kenya south to KwaZulu Natal in South Africa, in riverine conditions but also away from such habitats. Local names as for F. sycomorus.

Another important fig is F. vallis-choudae Del. (Maa: mutoyo, Pokot: nohow'o, Luo: ng'owo), a huge tree to 25 m high with a low crown, large heart-shaped to almost circular leaves, and large finely hairy, solitary figs to 5 cm in diameter. This tree is usually riverine.

Description: Spreading shrub or tree with a light crown and up to 7 m high. Branches hanging down. BARK: Smooth or fissured, dark grey. LEAVES: Usually asymmetrical at the base, whitish green underneath, margins toothed. FLOWERS: Yellow, on short stalks. FRUIT: Often divided into two lobes, each up to 0.7 cm, orange when ripe, rather hairy.

Ecology: Widely distributed in Africa and a common species all over Kenya, especially in lowlands in dry bushland, bushed grassland, 300-1,800 m. Soils very varied but mainly red clay, sandy and rocky soils. Zones III-V.

Uses: FOOD: Fruits eaten raw (+). The pulp, which is sweet but scanty, is sucked off the seeds and then the seeds are discarded. Occasionally the whole fruit may be crushed and eaten. Seeds are hard, however.

MEDICINAL: Bark chewed and placed on cuts as a bandage (Kitui). A cold infusion of the root is drunk for chest complaints (Maasai). Root decoction used for diarrhoea in humans and mixed with another species (sokotwo) for the extraction of the afterbirth in cattle (Pokot). The slimy pounded bark is applied locally for body itches.

OTHER: Sticks, bows and stirrers. Wood is tough and used to make knives, spears, clubs, bows, arrows, walking and fighting sticks (Daasanach), construction. Wood carving (Kamba). Bark used for string and rope. Animal fodder (++). Shade tree (++).

CULTURAL/BELIEFS: Leaves used by medicine men in exorcizing spirits and used to produce smoke in ceremonies for sick cattle (Pokot). Sticks used in an earthquake-prevention ceremony. Ritual sticks (Maasai).

Season: Flowers mainly in the rainy season. Fruits about 3 months later.

Status: Locally common.

Remarks: Most of the 27 or so species of Grewia occurring in Kenya have edible fruits. They are generally shrubs, rarely attaining tree size, usually multi-stemmed and more common in dry areas. Leaves are simple, alternate and toothed. Flowers usually have 5 coloured sepals, usually joined below, and 5 petals which are often shorter than the sepals and free. Many, usually 10, stamens. The fruit is normally hairy and divided into 2-6 lobes (often 1, 2 and 4).

Fruits with smaller lobes such as G. tenax, G. similis and G. tembensis can be chewed and swallowed whole. With the larger ones, one can only scrape off the thin sweet outer pulp then throw away the seed. Fruits eaten whole have better food value, especially proteins. The seeds are, however, known for their constipating property and ingesting large amounts may lead to serious constipation. Due to their high prevalence in the dry areas, Grewia fruits may form a substantial part of the daily diet among the pastoral communities. Apart from providing food, Grewia species are good sources of fibre. Their stems are often tough and durable, thus they find many uses in the household.

On mud or shallow water.

Uses: FOOD: Leaves eaten as a vegetable (+++) (Giriama, Duruma, Digo). The leaf blade is separated from the leaf stalk before cooking for a few minutes. Also used as a vegetable in Tanzania, South East Asia and China.

OTHER: Good fodder for most animals (+++).

COMMERCIAL: Leaves sold in Malindi.

Management: Propagated by rhizomes, stem runners and possibly seeds. Grows easily from cuttings.

Status: Locally common.

Remarks: A cultivated variety has been reported in Malawi. This species resembles the sweet potato (Ipomoea batatas (L.) Lam.) (Giriama: bwere, Sanya: chamai, Chonyi: mabwe (leaves), viyobwe (roots), Kisii: abanyabwasi), usually planted for its tubers, but also used as a leafy vegetable (some forms). The leaves are rather slippery and are normally mixed with other leafy vegetables such as cocoyam (maburu), pumpkin (mhango), Asystasia gangetica (thalakushe), okra and cowpeas (tsafe). They are, however, said to aggravate stomach ulcers (Mijikenda).The sweet potato, though a traditional crop in Africa, is native to South America.

Convolvulaceae

Giriama: kahedtho Kamba: ukwai-was-nthi, wimbia (Kitui), musele, uthui (Machakos) Maa: enkoeniyeni Samburu: lokiteng' Somali: bire, barfo

Description: A trailing plant often climbing on grass and other plants. Stems weak, hairy. LEAVES: Ovate, often heart-shaped, usually slightly hairy. FLOWERS: Funnel-shaped, white with purple centre in the corolla, occasionally mauve.

Ecology: Widespread in Kenya and also found in Tanzania in grassland, disturbed bushland, cultivated areas, 0-1,600 m. Common at 0-1,300 m. A common weed in cultivation often seen twining on other erect plants in cropland. Soils mainly sandy or light clay.

Uses: FOOD: Leaves used as a vegetable (+) (Turkana, Kamba, Giriama, Mijikenda). May be cooked alone or mixed with amaranth, Corchorus spp. and Oxygonum spp. This lessens the slippery texture of the vegetable.

OTHER: Fodder. Season: Rainy season.

Status: Common.

Remarks: This species may be a serious weed. A closely related species is I. plebeia R. Br. ssp. africana Meeuse (Turkana: ataakunyuk, ekeju-apoo, Somali: saarsaar) with a twining stem. Leaves somewhat triangular with a heart-shaped base. Corolla white with a purple centre. This species is also used as a vegetable (Turkana, Ng'ikebootok). Found in northern and eastern parts of Kenya and in southern Africa. A common trailing herb in open areas along the Turkwel River in southern Turkana.

Ipomoea oenotherae (Vatke) Hall. f.

Convolvulaceae

Kamba: nzola Kikuyu: nguirubi Kipsigis: robuoniot-ab-tirita Luo: ongeny Maa: oloiropiji, olorok-kilele, oloirobi-elongera Samburu: ldelopiji

Description: Small spreading herb rarely more than 15 cm high arising from a small carrot-like tuber. Stems several, arising from the top of the tuber, weak, thin, often prostrate or ascending. LEAVES: Of two types. Young leaves recently developed from the tubers are long, ascending and usually with few side lobes. Older leaves from the branches are deeply lobed and often smaller. FLOWERS: Purplish pink (mauve) usually opening in the morning. FRUIT: A small round capsule. Seeds few, grey or light brown. Tubers single or divided, up to 8 cm long by 2 cm wide, surface cream in young tubers, brown in older ones.

Ecology: Grows from Ethiopia and northern Somalia south to Zambia, Zimbabwe, South Africa and Namibia. In Kenya, e.g. at Ndaragwa (Nyandarua), Kaputei plains, Ildalalekutuk (Kajiado), Ong'ata Rongai (northern Kajiado), Nyandarua, Machakos, Makueni and Narok. Commonest in open grassland with short-grass species, 1,000-2,400 m. Common in the mid-altitudes, 1,500-1,800 m in rather damp but well-aerated clayish sandy soils, especially black cotton in transition to loam and in soils of volcanic origin. Rainfall: 650-1,200 mm. Zones: III-V.

Uses: FOOD: The carrot-like tuber is peeled and eaten raw (+++) (Kamba, Kikuyu, Samburu, Maasai, Luhya, Kuria, Luo, Pokot, Kipsigis). Tubers have the texture and taste of a raw sweet potato (Ipomoea batatas) and are much liked by children. Cooking not tried yet.

OTHER: Good fodder.

Management: Propagated by seeds or tubers. The seeds are produced in small numbers and so bulking is necessary before one has enough for planting. Seeds may be planted the same way carrots are planted. Germination is within a few days. If conditions are favourable, good-sized tubers are seen within 2-3 months. Fruits containing seeds should be collected as soon as they turn brown and kept to dry ready for planting the following season. The shoot dries off leaving the tubers below the ground and it is in this form and from the seeds that the species is able to survive the dry season. Young leaves sprout soon after the start of the next rainy season.

Status: Occasional. Encroachment of its grassland habitat by expanding human population, coupled with overgrazing and the poor rate of production, are threatening this species.

Remarks: Two varieties are distinguished:

· var. oenotherae with a corolla over 2 cm long. Found in Uganda, Tanzania, Ethiopia, northern Somalia, south to South Africa and Namibia.

· var. angustifolia (Oliv.) Verdc, has smaller flowers, the corolla hardly exceeding 1.5 cm and with narrow leaves and lobes. It is found only in western and north-western Kenya and in Uganda.

Description: Tree to 12 m high (usually 5-8 m) with a light to medium dense rounded crown. LEAVES: Large, divided into 7-9 leaflets. Leaflets very rough and stiff with an entire or serate margin and asymmetrical base. FLOWERS: In panicles, red, large and hanging. FRUIT: Long, usually 30-40 cm, sausage-like and hanging on long stalks. Very variable.

Ecology: Widely distributed in Kenya and the rest of Africa in wooded grassland, shrubland and riverine vegetation. Common on hillsides, 0-2,200 m. Loam, red clay or rocky ground. Rainfall: 500-1,500 mm. Zones II-V.

Uses: FOOD: Fruits, split in half longitudinally, are widely used for fermenting traditional beer (Kamba, Kikuyu, Mbeere, Embu, Tharaka, Giriama, Digo). The soft inner tissue is cleaned out in hot water then dried and inoculated with the fermenting agent by mixing with old fruits (Kamba). To ferment beer, these fruits are left in a solution of water and sugar or honey for 3-5 days. A wide-mouthed gourd (Lagenaria siceraria) is the preferred container. This is placed near the fireplace in the house.

CULTURAL/BELIEFS: Plant revered in many communities. Often preserved. Fruit buried instead of the body of a lost person believed to be dead (Luo).

COMMERCIAL: Fruits occasionally seen in market places (Makueni, Machakos, Kitui, Mwi, Tharaka, Embu, Meru).

Season: Flowers in December-January (Kitui). Fruits in April-May in Kitui, Machakos, Tharaka, Makueni, Mwingi.

Status: Occasional but not threatened.

Remarks: May be a good ornamental plant. For fermentation the Maasai also use the roots of Aloe species (Kamba: kiluma, Kikuyu: kiruma, muguna nugu, thukurui, Maa: osuguroi, Meru: kiluma, Kipsigis: tangaratwet, Luo: ogaka, Tharaka: kiruma, Turkana: echuchuka). Several species of Aloe are used for this purpose (A. secundiflora Engl., A. deserti Berger, A. ngongensis Christian, A. kedongensis Reynolds).

Aloes are perennial fleshy-leaved plants. Some are small and almost stemless while others attain tree size. Over 30 species have been recorded in Kenya. Uses: Nectar from the flowers of A. secundiflora is sucked by children (Machakos, Kajiado). The sweet base of the inflorescence may be chewed. The sap from the leaves of most species is applied to wounds to keep flies away. Leaves are dropped into drinking water for chickens as a treatment for coccidiosis and Newcastle disease.

Lablab purpureus (L.) Sweet

Papilionaceae (Fabaceae)

syn: Dolichos lablab L., D. purpureus L., Lablab niger Medic., L. vulgaris Savi

Borana: marage Chonyi: mpupu, pupu (fruit) Embu: njavi, njabi nzavi English: hyacinth bean, bonavist bean, lablab bean Giriama: mpupu Kamba: mbumbu, ngiima, nzavi Kikuyu: njahi Luhya (Bukusu): njawu, sikandakanda Luhya (maragoli): ihranda Maa: ormbombo, mbombo, irpombo Mem: njabi, ncabi Nandi: mangwanyet Samburu: lagat Sanya: pupu Swahili: mfiwi, fiwi (fruit) Tharaka: njavi

Description: A climbing perennial with thick foliage. LEAVES: With 3 leaflets, to 15 cm long. FLOWERS: Of varying colours, borne on long-stalked erect inflorescences arising from the leaf axils. Purple or cream with purple tinge. The wild subspecies uncinatus has a white keel and the standard and wing purple to violet. FRUIT: A pod variable in shape and size: broad and short (to 4 cm long by 1.5 cm wide) in ssp. uncinatus; a bit larger (up to 10 cm long) but the same shape in ssp. purpureus; long (up to 14 cm) and slender, resembling kidney bean in ssp. bengalensis of Indian origin. Seeds pink, reddish brown to black, white, or mottled red with a white hilum and a long aril.

Ecology: Cultivated mainly in the Coast, Central, Eastern and Rift Valley (central part) Provinces, 0-2,500 m. Also in the rest of Africa and in Asia. In the wild state, found climbing on other plants at the edges of riverine forest and in mountain forest. Cultivated in various types of soils. Propped up or planted with other less leafy plants where it can get support. Rainfall: 600-1,200 mm. Zones II-V.

Uses: FOOD: Dry or green beans are cooked and eaten (Kikuyu, Kamba, Maasai, Meru, Embu, Nandi), often being soaked before cooking. Beans cooked for 2-3 hours, water used to boil seeds may or may not be poured out. The beans can be cooked with vegetables or maize (Kamba, Kikuyu) or mashed with potatoes (Kikuyu). Seeds may also be boiled, fried and used as mboga (relish) with ugali. An important traditional food among the Kikuyu, almost always served to recuperating mothers after childbirth (said to increase mother's milk), important visitors (such as in-laws visiting a child named after them) and during important ceremonies. Leaves occasionally used as a vegetable in Central and Coast Provinces but a good knowledge of preparation is needed.

OTHER: A fodder crop.

Season: First crop harvested after 3½ months (at about the same time as maize). Continues to bear a crop so long as there is water in the ground, hence preferably planted in moist places.

Management: Propagated by seed. Said to be planted with other crops but preferably at the edge of cropland. Staked or planted near hedges to climb on. Pods are normally harvested individually as they mature. The same plant may produce a crop for several years.

Remarks: This bean is very variable with at least three subspecies in Kenya:

· ssp. uncinatus Verdc, is the wild form of local origin but also cultivated. Distribution: Throughout tropical Africa and south to South Africa.

· ssp. purpureus is the form widely cultivated throughout the tropics.

· ssp. bengalensis (Jacq.) Verdc. is a widely cultivated variety of Asian origin with long pods. This form is also grown in Kenya.

All the varieties are still grown in Kenya and are distinguished by the shape and colour of the seeds and pods. Seeds may be black, brown, white, speckled red or red. In Kitui the first two are referred to as mbumbu while the last three are known as ngelenge. The taxonomy of these last three with reference to the others is still dubious. Seeds of the red type may change to being poisonous after a few generations, a property which some seeds are said to have acquired at the middle of the century. To be on the safe side, throw away the first two rounds of the water used for boiling.

These are very drought-resistant pulses. Nowadays less commonly grown and the population is barely maintained by spontaneous growth in cropland or its edges. The consumption and cultivation of this bean have diminished over the years, and its place has been taken by kidney beans, peas and cowpeas. It is, however, a drought-resistant plant that should not be forgotten, especially in drier areas.

Description: A monoecious annual, long-trailing or climbing herb with divided tendrils. LEAVES: Simple, kidney-shaped. FLOWERS: Male solitary, borne on long stalks, large, white, axillary, with funnel-shaped tube, opening in the evening. Female with short tube. FRUIT: Young fruit softly hairy, variable in colour from green, speckled to cream or pale yellow. Mature fruit with a dry, usually brown, hard but brittle shell with a smooth or warty surface. Cultivated forms very variable in shape and size, 5-100 cm or more long. Shapes may vary from spindly to spherical with almost infinite intermediate shapes- constricted, crescent-shaped, cylindrical, etc. Seeds cream to brown, compressed, embedded in a white spongy pulp. The size and shape of gourds is both genetically and environmentally determined. Flowers produced first give rise to bigger gourds as the growth of the plant is vigorous.

Ecology: L. siceraria is believed to be of African origin. Now widely grown in Kenya for its fruits which are used as containers and often escaping to the wild, 0-2,800 m. Cultivated 0-2,500 m. Escapes common in the wetter areas, especially central highlands of Kenya and the Rift Valley west to Nyanza and Western Provinces. A traditional crop in many African cultures. Cultivated throughout the tropics and subtropics of both the New and Old World. Riverine and lakeshore conditions, in grassland and bushland. Common in abandoned homesteads. Pound in a wide range of soil types but common in well-aerated, fertile soils. Rainfall: 400-1,500 mm. Needs well-distributed rain. Moisture crucial during fruit growth since drought leads to dropping of the immature fruit. Zones I-VI.

Uses: FOOD: Young, tender fruits of some small cultivars are eaten as a vegetable. The cooked fruit is soft, slightly sweet or almost without taste. These "sweet" types (Kikuyu: mungu, Kamba: ungu wa muyo, makii (Luo, Homa Bay), nyatao (Giriama: vimumunye) may be boiled, salted and eaten or boiled, mashed, fried and made into a stew. Mature fruits turn somewhat bitter and are not used as food. The seeds are edible and in some cultivars are high in protein and oil. Young shoots and leaves of some cultivars (Luo: maguti) are used as a leafy vegetable (Luo, Mijikenda). Several forms of these edible ones have been noted.

Edible gourds have variable shapes and sizes: they may be small, elongate with a smooth surface or spherical or nearly so with numerous lumps on the shell (Luo: budh-nyatao). Most other gourd cultivars, especially those producing large fruit, are bitter even when young and cannot be eaten. Neither are the leaves eaten. These should not be confused with those of the pumpkin (Cucurbita spp.) which are widely cooked as a vegetable.

MEDICINAL: Roots and fruit are used as a purgative in some communities.

OTHER: Both edible and inedible cultivars are cultivated for a wide range of uses depending on their shape and size. The use of the gourd as a container is common in many African cultures, cultivators and pastoralists alike. When cut into two halves the various types, including the edible ones, find new uses-as open containers used for storage, ladling out food, fluids, seeds, etc., and as a cup, bowl or plate. Different cultivars have specific shapes with different end uses.

COMMERCIAL: Various forms of gourds are sold either as containers or in halves used as bowls or ladles. The very small ones are sold as household ornaments (Nairobi). The long snake gourds are grown in Murang'a and sold among the Maasai where they are still valued as containers for milking and bottles for a child's milk.

Season: Planted during the rainy season. Flowers in January-February in Makueni. Fruits in April-May in Makueni and Kajiado.

Management: Gourd plants grow easily from seed. Seedlings require well-aerated, fertile soils. Traditionally seeds for next season's planting may be in the form of stored gourds, or even seeds from broken gourds left in cropland. The plant is normally planted at the edge of cropland, next to a fence or on terraces to minimize on use of cropland. Among the Maasai the plants are not usually planted but grow spontaneously near cattle enclosures, on fences and in abandoned homesteads from where they are harvested. Occasionally there is deliberate propagation when seeds are broadcast at specific places or seedlings uprooted from the wild and planted in the homestead (Maasai, Bukusu). The plant climbs on hedges, becoming further strengthened. The shape of the container is affected by its position during growth. Among the Mbeere, Tharaka and Kamba, the gourds are placed upright on flat ground so that they form with a flat bottom-to be stable later when in use.

The fruit is harvested when the shell hardens and outer and inner layers begin to turn yellow. The container is prepared by soaking its contents (seeds and pulp) in water, dislodging the pulp with a stick, shaking it vigorously and emptying the contents.

Status: Species as a whole not threatened but genetic erosion taking place fast.

Remarks: Other important members of the genus are L. sphaerica (Sond.) Naud., an extensive climber, and L. abyssinica (Hook f.) C. Jeffrey, widespread from Kajiado and Embu to western Kenya. Common in bushland and evergreen forest.

CULTURAL/BELIEFS: A ritual plant (Mbeere).

Season: Fruits in May-July and January-February.

Status: Common.

Remarks: A potential hedge plant and ornamental. Virtually all Lantana species in Kenya have edible fruit. These include:

· L. ukambensis (Vatke) Verdc. (syn. L. rhodesiensis Mold.) (Kamba: muvisavisi) a small plant to 1.5 m high, often multi-stemmed with ovate leaves which are paired or in whorls of threes. Corolla reddish purple, often with a white centre, generally shorter (less than 2 mm at apex). Found in Trans Nzoia, Uasin Gishu, Murang'a, most of Africa.

· L. viburnoides (Forssk.) Vahl, has opposite leaves and usually white (rarely pink) flowers (Somali: geedxamar). It is an important fodder and is used in the preparation of male and female aphrodisiacs (Tharaka). Distribution: Egypt south to Angola, Mozambique.

· L. camara L. (Chonyi: mshomoro, Digo: shomoro mjesasa, English: curse of India, tick-berry, Giriama: mushomoro, Kamba: mukiti, musomolo, Kikuyu: mukigi, kagiri, rutana, nyatana, mushomoro, mucimoro, Luo: obengle, onyalobiro (both Homa Bay), tek-taguari, nyamridhi (both Siaya), Mbeere: musamburu, mucimoro, Meru: mucimoro (in Mwimbi), Sanya: mushomoro, Somali: dumod, Swahili: mshomoro, Taita: mvudi, mwemberi) is of American origin and now widely distributed in the tropics and subtropics. It has prickly stems and larger (5-8 mm) blue-black fruits. It has been spread by running water and birds, which feed on it, to become a major weed in all agricultural zones. It is common in mid-altitudes forming dense thickets. In Nyanza Province these have provided an ideal habitat for tsetse flies and hence the persistent problem of trypanosomiasis in the region. The fruits are edible and are also used as a dye for baskets (Kitui).

Description: Erect herb with underground rhizomes. Usually 0.3-1.5 m, branching above into branchlets which end in flower heads. LEAVES: Grey-green, long, narrow, lobed laterally, often on one side and with a toothed margin. FLOWERS: Yellow, borne on numerous heads.

Ecology: Widely distributed in Kenya in cultivated land, abandoned cultivation, at roadsides, disturbed grassland, 0-2,000 m. Found on all soil types from sandy to black-cotton soils. Seems to prefer sandy soils. Zones II-V.

Uses: FOOD: Eaten as a vegetable (Kamba, Kikuyu, Luo, Giriama, Taita). Often cooked with Solarium nigrum leaves. Vegetable said to be good for stomach disorders, ulcers, dysentery, etc. (Taita, Kamba). An important vegetable among the Giriama, often cooked during wedding ceremonies (+++).

FOOD/MEDICINAL: Vegetable believed to have curative as well as prophylactic properties against malaria.

MEDICINAL: Leaves given to chickens for mavui (lung diseases) (Kamba).

OTHER: Fodder, especially for rabbits.

COMMERCIAL: Leaves sold in most coastal urban centres.

Management: Not normally planted as it is a common weed where it is used as a vegetable. May be grown from stem bases which have some roots. The plant readily sends out new shoots even in dry weather and when harvested intensively.

Status: Very common.

Remarks: Among the Chonyi, the name mutsunga is occasionally used as a general term for a leafy vegetable. Among the Mijikenda this vegetable is never cooked alone. It is usually mixed with less bitter ones such as Asystasia gangetica (talakushe), amaranth, pumpkin leaves, cowpea leaves and Vernonia cinerea, but never with sweet potato leaves, okra leaves, Corchorus spp. and Oxygonum salicifolium (kimbiri), which are slippery. This vegetable is very important in Mijikenda culture. Its preparation is considered an important role of a married woman and is often given as the reason why a bride should leave her parents for her new home (Giriama). Related to this species is the exotic Sonchus oleraceus (sow thistle) whose leaves are occasionally used.
