Chamaecrista comprises the following species, organized into sections, subsections, and series:[2][4][5][6][7][8]
Series Apoucouita
Series Pteridophyllae
Subsection Absus DC. ex Colladon
Series Absoideae
Series Adenophyllae
Series Andromedeae
Series Atroglandulosae
Series Bracteolatae
Series Catharticae

Series Rigidulae
As traditionally circumscribed here, Chamaecrista ser. Rigidulae is polyphyletic. However, the series is monophyletic if redefined to exclude C. brachyblepharis and C. ciliolata and include C. sincorana and C. botryoides (from series Microphyllae). The species in the series are all endemic to Brazil and can be divided geographically into two main lineages, one from the highlands of Goiás, and the second from the Espinhaço Range of Bahia and Minas Gerais.[9]
