Description from Flora of China
Acaciella Britton & Rose; Racosperma Martius; Senegalia Rafinesque; Vachellia Wight & Arnott.
Morphological characters and geographic distribution are the same as those of the tribe.
The genus is treated here sensu lato, including the African, American, Asian, and Australian species.
Acacia senegal (Linnaeus) Willdenow and A. nilotica (Linnaeus) Delile were treated in FRPS (39: 28, 30. 1988) but are not treated here because they are only rarely cultivated in China.
