Résumé :	A new Rennera species (Asteraceae, Anthemideae), Rennera stellata P. PJ. Herman sp. nov. from the North-West and Northern Cape Provinces, Republic of South Africa, is described. It is characterized by cypselas with five wings radiating stellately apically, and occurs in calcrete pans on unweathered calcrete rock. The genus description is emended to include the characters of all four now known species occurring in the Flora of southern Africa region. The anatomy and surface structure of the cypselas of the four species are described, and a key is provided to separate them. A synopsis of the species is given.
