Summary. The genus Duosperma from eastern and southern Africa with one species extending to the Yemen is revised. 26 species (one with three subspecies) are recognised. Eleven species and two subspecies are described as new and four new combinations are made. The delimitation and affinities of the genus are discussed. There are chapters on history, morphology and phytogeography. The paper is illustrated with line drawings and the distributions of all taxa are mapped.
