Cassia nictitans L. Chamaecrista procumbens 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.

[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 generally smaller,[4] it is less robust, and the flowers are smaller and inconspicuous.

[8] Chamaecrista nictitans is undesirable as a forage or hay but can be used for both in subtropical areas.
