Abstract
Chamaecrista falcata Musandiwa & Boatwr., a new species from the northern coastal regions of KwaZulu-Natal and the Waterberg in Limpopo, is described bringing the number of recognised species of Chamaecrista in southern Africa to 13. This taxon was previously confused with Chamaecrista capensis and treated under this species in the Flora of Southern Africa. The new species shares stipitate extrafloral nectaries with Chamaecrista grantii but is distinguished by its falcate leaflets with a strongly excentric midrib. A detailed description of the new species is presented, together with a distribution map and illustrations of its diagnostic characters.
