Abstract
We carried out genetic and morphometric analyses in 33 populations belonging to all nine described and one putative taxa of Chamaecrista subsect. Baseophyllum. Genetic variability was low in all taxa. Morphological and genetic data are consistent with the status of C. depauperata and C. coriacea. However, divergence between C. cytisoides var. cytisoides and all the other six conspecific varieties is higher than the divergence between it and the other two species. Our data support the recognition of eight species in the subsection Baseophyllum. Chamaecrista coriacea and C. depauperata are supported in their original circumscription. However, the varieties ascribed to C. cytisoides are best treated as six different species. We propose five new combinations in order to raise varieties of C. cytisoides to specific rank: C. blanchetii, C. brachystachya, C. confertiformis, C. decora, C. unijuga. We also propose synonimization of one variety, C. cytisoides var. micrantha, under C. brachystachya.
