(1833) Dichrostachys is an Old World genus of flowering plants in the family Fabaceae.

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.

[2] Their name is derived from the Greek words dis (two), chroos (colour) and stachys (grain ear or spike), which in combination suggests their bi-colored inflorescences.

[2] 16 species are accepted:[1] This Mimosoideae-related article is a stub.
