Dichrostachys is an Old World genus of flowering plants in the family Fabaceae. Their Acacia-like leaves are bi-pinnately compound. Unlike Acacia their thorns are hardened branchlets rather than modified stipules. They are native from Africa to Australasia, but a centre of diversity is present in Madagascar.
