Chamaecrista

provided by wikipedia EN

Chamaecrista is a genus of flowering plants in the pea family, Fabaceae, subfamily Caesalpinioideae. Members of the genus are commonly known as sensitive pea.[3] Several species are capable of rapid plant movement. Unlike the related genera Cassia and Senna, members of Chamaecrista form root nodules.

Species

Chamaecrista comprises the following species, organized into sections, subsections, and series:[2][4][5][6][7][8]

Series Pinifoliae

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.
