Abstract
The morphology is documented for the two species of the genus Astephanus R. Br. (Apocynaceae - Asclepiadoideae - Asclepiadeae), A. triflorus (L. f.) Schult. and A. zeyheri Turcz., which occur in the southwestern corner of southern Africa. Astephanus marginatus Decne. is a synonym of A. triflorus and so the earliest valid name for plants commonly known as A. marginatus is A. zeyheri. The similarities and differences from the closely related genus Microloma R. Br. are discussed. Various species from the New World have been included at one or other time in Astephanus. These are now excluded and a list of them is given, with their present taxonomic position.
