The Mimosoideae are a traditional subfamily of trees, herbs, lianas, and shrubs in the pea family (Fabaceae) that mostly grow in tropical and subtropical climates. They are typically characterized by having radially symmetric flowers, with petals that are twice divided (valvate) in bud and with numerous showy, prominent stamens.
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.
Dalea is a genus of flowering plants in the legume family, Fabaceae. Members of the genus are commonly known as prairie clover or indigo bush. Its name honors English apothecary Samuel Dale (1659–1739). They are native to the Western hemisphere, where they are distributed from Canada to Argentina. Nearly half of the known species are endemic to Mexico. Two species of Dalea have been considered for rangeland restoration.
Chamaecrista is a genus of flowering plants in the pea family, Fabaceae, subfamily Caesalpinioideae. Members of the genus are commonly known as sensitive pea. Several species are capable of rapid plant movement. Unlike the related genera Cassia and Senna, members of Chamaecrista form root nodules.
Swartzia is a genus of flowering plants in the family Fabaceae. It was named in honor of Swedish botanist Olof Swartz and contains about 200 species. Swartzia is restricted in its geographical distribution to the New World Tropics, where it occurs primarily in lowland rainforests, but also in savannas, pre-montane forests, and tropical dry forests. While it can be found throughout the wet lowlands from Mexico and the Caribbean islands to southern Brazil and Bolivia, Swartzia is most abundant and species-rich in Amazonia, where 10–20 species may co-occur at a single site. The species of Swartzia are mostly trees, ranging from small understory treelets to large canopy emergents. Some species, especially in savannas, are mult-stemmed shrubs.
Zygia is a genus of flowering plants in the family Fabaceae. It includes 60 species of tres and shrubs native to the tropical Americas, from Southern Mexico and Cuba to northern Argentina. Typical habitats are tropical forest and coastal zones, generally below 900 meters elevation with a few species extending up to 2800 meters. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.
Aeschynomene is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. They are known commonly as jointvetches. They range across tropical and subtropical regions of the Americas, sub-Saharan Africa, south, southeast, and east Asia, and Australia. These legumes are most common in warm regions and many species are aquatic.
Zapoteca is a genus of flowering plants in the family Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It was separated from the genus Calliandra in 1986 on the basis of chromosome numbers, pollen, seedling structure, and other features. It is named in honour of the Zapotec peoples.
Senegalia is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of Acacia. The genus was considered polyphyletic and required further division, with the genera Parasenegalia and Pseudosenegalia accepted soon after.
Galactia is a genus of plants in the legume family (Fabaceae). It belongs to the subfamily Faboideae and tribe Diocleae They do not have an unambiguous common name, being commonly called milk peas, beach peas or wild peas. They are perennial herbs or subshrubs with prostrate, climbing, or erect forms.
Harpalyce is a genus of flowering plants in the family Fabaceae. It belongs to the subfamily Faboideae. It includes 35 species of shrubs and small trees native to the tropical Americas. Their distribution is disjunct, ranging from Mexico to Nicaragua, Cuba, and northern to southeastern Brazil and Bolivia. Typical habitats include seasonally-dry tropical forest, warm-temperate humid forest, woodland, bushland and thicket, shrubland, and grassland. Most species are evergreen and flower during the dry season.
Schnella is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Cercidoideae. All of its species are neotropical lianas.
Jupunba is a genus in the family Fabaceae. It is native to region from South Mexico extending to tropical America.
Libidibia is a genus of flowering plants in the family Fabaceae. It includes seven species of trees and shrubs native to the tropical Americas, ranging from northern Mexico to northern Argentina. Typical habitats include seasonally-dry tropical forest and scrub, thorn forest, and savanna woodland. It belongs to the subfamily Caesalpinioideae.
