Chamaecrista nictitans
Species of legume
Chamaecrista nictitans, the sensitive cassia,[2] sensitive partridge pea,[3] small partridge pea[4] or wild sensitive plant,[4] is a herbaceous species of legume widely distributed through the temperate and tropical Americas.[5] It is an annual plant capable of rapid plant movement—its leaflets fold together when touched.[6] However, a population at Haleakala National Park on the island of Maui, Hawaii, was reported as not being sensitive to touch.[7]
It is similar to Chamaecrista fasciculata except that the leaves are smaller.[4]
Chamaecrista nictitans is undesirable as a forage or hay but can be used for both in subtropical areas.[8]
