Eighty-two genera and 3275 species (cosmopolitan but absent from north temperate regions), of which 14 genera and 106 species are native to southern Africa, an additional four genera and 28 species are naturalised, and an additional 11 genera and 96 species are cultivated in the region.

Genera native to southern Africa

List from Germishuizen (2000).

Acacia

About 900 species, mainly in tropical and subtropical regions, particularly in Australia and Africa. There are 58 species native to southern Africa, 17 naturalised, and an additional 62 species that are cultivated in the region (mainly originating from Australia). Acacia in the broad sense is not monophyletic and has been split into a number of different genera. However, there has been controversy over the use of the name Acacia for the Australian group of species when in fact it belongs to the African species. African botanical sources are still using Acacia for the African species and this practice is followed here until there is better consensus.

Adenopodia

About 10 species found mainly in tropical regions. One species, Adenopodia spicata, is native to southern Africa. 

 

Albizia

About 145 species, distributed from Africa to Asia and Australia. There are 17 species native to southern Africa, three species that are naturalised to the region, and an additional eight species that are cultivated in the region.

Genera naturalised in southern Africa

List from Germishuizen (2000).
