Senegalia nigrescens, the knobthorn, is a deciduous African tree, growing up to 18 m tall,[1] that is found in savanna regions from West Africa to South Africa. The tree is resistant to drought, not resistant to frost and its hard wood is resistant to termites.[1]
Giraffes often browse on the flowers and foliage of this tree, while the seed pods and foliage are browsed on by a range of mammals, including elephants.[2]
An ointment made from the roots has traditionally been used to treat convulsions.[3]
