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.
Chamaecrista has 367 species, with a wide distribution – the Americas from Minnesota to northern Argentina, sub-Saharan Africa, the Arabian Peninsula and Iran, the Indian Subcontinent, Indochina, China, Korea, Japan, Malesia, New Guinea, and Australia. [1]
Chamaecrista comprises the following species, organized into sections, subsections, and series: [2] [4] [5] [6] [7] [8]

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.
