A revision of the 'Spiny Solanums', Solanum subgenus Leptostemonum (Solanaceae), in Africa and Madagascar. 2016. (Systematic Bot. Mon.,99). illus. 432 p. gr8vo. Hardcover.
The treatment is based on the examination of over 10,000 herbarium specimens and on field work in the center of species diversity in the group. All spcies of the region are included in this treatment to assist with identification. The center of both richness and endemism of native species is in East Africa (with 33 endemic species, focused on Kenya and Tanzania). Secondary centers of diversity occur in South Africa (12 endemic species). Both a dichotomous key and a synoptic character list are presented to aid with identification of these highly variable species. Full descriptions and synonymies (including designation of lecto - and neotypes), illustrations, distributionmaps, and discussion concerning similar and potentially related taxa are provided for all accepted species.
