Senna obtusifolia, known by common names including Chinese senna, American sicklepod and sicklepod, is a plant in the genus Senna, sometimes separated in the monotypic genus Diallobus. It grows wild in North, Central, and South America, Asia, Africa, and Oceania, and is considered a particularly problematic weed in many places. It has a long-standing history of confusion with Senna tora and that taxon in many sources actually refers to the present species.
Senna, the sennas, is a large genus of flowering plants in the legume family. This diverse genus is native throughout the tropics, with a small number of species in temperate regions. The number of species is estimated to be from about 260 to 350. The type species for the genus is Senna alexandrina. About 50 species of Senna are known in cultivation.

Chamaecrista nictitans, the sensitive cassia, sensitive partridge pea, small partridge pea or wild sensitive plant, is a herbaceous species of legume widely distributed through the temperate and tropical Americas. It is an annual plant capable of rapid plant movement—its leaflets fold together when touched. However, a population at Haleakala National Park on the island of Maui, Hawaii, was reported as not being sensitive to touch.
Chamaecrista glandulosa is a species of flowering plant in the legume family native to the Americas. Its distribution extends from Mexico to Brazil and it occurs on many Caribbean islands.
Chamaecrista rotundifolia, the round-leaf cassia, also known as pasto rastiero, roundleaf sensitive pea, and Wynn cassia, is a short-lived perennial or self-generating annual plant in the subfamily Caesalpinioideae of the family Fabaceae.

An annual herb reaching 60 cm (24 in), it is a common weed of cultivated and waste places, and its seeds are regularly harvested and sold for use in traditional medicine in Africa and Asia.
