Crotalaria podocarpa DC. and C. damarensis Engl. original illustration from Flora Zambesiaca. C. podocarpa is widespread in the drier parts of the Sudanian and Zambezian Domains of Tropical Africa. It tends to occur in mopane woodland (rarely in miombo), Acacia and Combretum tree savanna and grassland, usually on sandy soils, often in temporary water catchment areas by roads, pans and rock outcrops, at altitudes of up to 1100m. C. damarensis is similar to C. podocarpa in its morphology. C. damarensis is also distributed in SW Angola, Namibia, and S. Africa, occurring in mopane woodland, along river banks and in disturbed places on sandy soils, at altitudes of 300-900m (Pope, Polhill & Martins, 2003).
