Abstract
Cassiinae is a large subtribe of the tribe Cassieae (Caesalpinioideae) that comprises
ca. 700 species distributed throughout the Americas, Africa, Eurasia and Australia.
The southern African species of Cassiinae (indigenous, naturalised and cultivated)
were all treated under Cassia L. in Gordon-Gray’s (1977) treatment for the Flora of
southern Africa. However, given the subsequent generic recircumscriptions in the
subtribe and the expansion of collections of these taxa since, this treatment is now
outdated. The aim of the present study was to provide an overview of the subtribe
Cassiinae in southern Africa, assess the invasive potential of all naturalized species
(viz. Cassia s.s., and Senna Mill.) and conduct a detailed taxonomic revision of the
species of Chamaecrista (L.) Moench. indigenous to southern Africa.
