Abstract

The wide morphological variation observed in Chamaecrista diphylla was analyzed using morphological and molecular data. Three distinct morphotypes were identified, namely: a morphotype corresponding to the original description of Chamaecrista diphylla, a second morphotype corresponding to the original description of the synonym Chamaecrista cultrifolia, and a third morphotype with shared characteristics of the other two, which in the molecular analyses grouped with the C. cultrifolia morphotype. Chamaecrista cultrifolia is re-established as a distinct species, but its circumscription is emended to include the third morphotype identified in the morphological and molecular analyses of this study.
