Sclerocarya birrea, the marula, is a medium-sized dioecious tree, indigenous to the miombo woodlands of Southern Africa, the Sudano-Sahelian range of West Africa, and Madagascar. The tree is a single stemmed tree with a wide spreading crown. It is characterised by a grey mottled bark. The tree grows up to 18 m tall mostly in low altitudes and open woodlands. The fruits are used in the liqueur Amarula. The distribution of this species throughout Africa and Madagascar has followed the Bantu in their migrations, as it has been an important item in their diet since time immemorial.
