Abstract

Pachycarpus acidostelma M. Glen & Nicholas (Apocynaceae, Asclepiadoideae) is a new species described from the KwaZulu-Natal Province of South Africa. The new taxon is differentiated from other closely related Pachycarpus E. Mey. species (P. scaber (Harv.) N. E. Br. and P. asperifolius Meisn.) by its small stature, the catilliform or saucer-shaped corolla, and a deltoid corona lobe that is sharp at the distal end, hence the specific epithet. It also differs from P. asperifolius in the inflorescence being terminal and subcorymbose.
