Vachellia erioloba (camel thorn, giraffe thorn, Afrikaans: Kameeldoring, Tswana: Mogôtlhô, Sotho: Mogohlo)[2] is a southern African legume.[3] Its preferred habitat is the deep dry sandy soils of the Northern Provinces, western Free State, northern Cape Provinces, Botswana, and the western areas of Zimbabwe and Namibia. It is also native to Angola, south-west Mozambique, Zambia, KwaZulu-Natal, and Swaziland.[4] The tree was first described by Ernst Heinrich Friedrich Meyer and Johann Franz Drège in 1836.[4]
The tree can grow up to 17 metres high and is commonly found in Namibia. Its name refers to the fact that giraffe (kameelperd in Afrikaans) and camels commonly graze on the harder-to-reach succulent leaves normally out of reach of smaller animals. Giraffe in particular are partial to all vachellias and manifest a specially-adapted tongue and lips that can cope with the vicious thorns. It also grows ear-shaped pods, which are favoured by a large number of herbivores including cattle. The wood is dark reddish-brown in colour and extremely dense and strong. It is slow-growing, very hardy to drought and fairly frost-resistant.
The wood is a good fuel for fires, which leads to widespread clearing of dead trees and the felling of healthy trees. According to superstition, lightning will strike at V. erioloba more often than other trees.[5] The camel thorn's seeds can be roasted and used as a substitute for coffee beans.[5] The camel thorn is a protected tree in South Africa.[2]
