Notes.

Acridocarpus currently comprises 36 accepted species (19 threatened species; Suppl. material 1) of trees, shrubs, scandent shrubs, or lianas endemic to rainforests, savannas, and seasonally dry tropical forests of Africa, Madagascar, the Arabic Peninsula, Iran, and Oceania (i. e., New Caledonia; POWO 2024). There is no updated identification key for all species of Acridocarpus, but Niedenzu’s (1928) treatment covers 25 out of the 36 currently accepted species.
