Adenium oleifolium Stapf

Adenium oleifolium occurs in South Africa and extreme southern Botswana. It is the smallest species in the genus. The caudex is subterranean, and the stems are scarcely succulent and rarely reach a foot tall. The small flowers are usually pale pink, with a yellow throat and prominent red nectar guides. The anther appendages are just shorter than the tube, or may be slightly exserted.
