Balanites rotundifolia, known inSwahili asMbamba ngoma is a spiny bush or small tree from eastern Africa and southernArabia. It is a member of thecaltrop family,Zygophyllaceae.[citation needed]
Balanites rotundifolia is a small tree or shrub with a multi-stemmed growth form and spiny branches which grows to 2-5m. The small, round or heart shaped leaves are green, rather hairy, grow in pairs and lack stalks. The stout thorns are green, straight and grow to 3 cm in length. The greenish white flowers grow from the thorns and the small hairy fruit is 2 cm in length.[2] When the fruit is ripe it is orange-yellow in colour.[3]
Balanites rotundifolia is found in eastern Africa fromSomalia andSomaliland intoSudan, and also inYemen, specificallyAden.[3][4]
Balanites rotundifolia occurs in arid tree savanna or scrub; semi-desert scrub; deciduous bushland and open woodland. It is often found growing in thin soils over lava or near rivers; it can be the dominant species in some habitats such asraised beaches oversandstones.[4] Fruiting in Kenya occurs in February and in October and November.[2] Often grows in association withAcacia,Commiphora orCombretum in arid areas.[3] The flowers are pollinated by bees.[4]
The ripe fruit has an edible and sweet pulp, the ripe fruits are either picked from the tree or gathered from the ground. The fruits are eaten as a snack, particularly by herdsmen.[4] The seeds are edible if they are boiled for 3–4 hours, they are normally eaten with milk. The fruit pulp is fermented to make a local brew.[2]
The wood is used to smoke food for flavour and to sterilise milk containers.[2]
Balanites rotundifolia is the source of a gum resin calledHanjigoad, which is used for chewing and is collected as tears or globular pieces.[5]
The wood is used as firewood and to make charcoal. It is fashioned into poles, tool handles, carvings, utensils (e.g. head rests, wooden spoons and combs).[2]
The leaves and shoots provide fodder for domestic animals in very arid areas.[3]
It is used for live fencing and the cut branches are used to make fences, it is also planted in soil conservation projects.[2] There are no known medicinal applications.[4]
