The acaulescent and succulent species of Dorstenia sect. Kosaria in NE tropical Africa include the well defined D. ellenbeckiana and the two polymorphic taxa, the D. barnimiana complex and the D. foetida complex. The D. barnimiana complex is treated as two species, D. barnimiana Schweinf. and D. tropaeolifolia (Schweinf.) Bureau. One specific name and four varietal names are reduced to synonymy. The D. foetida complex is treated as one species, D. foetida (Forssk.) Schweinf., with two subspecies, ssp. foetida and ssp. lancifolia (Rendle) Friis comb, nov., of which the former is further divided into var. foetida and var. obovata (A. Rich.) Schweinf. & Engl. Three species arc reduced to synonymy of D. foetida. The distribution of all the species is mapped.
