Mimosa is a genus of about 600 species of herbs and shrubs, in the mimosoid clade of the legume family Fabaceae. Species are native to the Americas, from North Dakota to northern Argentina, and to eastern Africa as well as the Indian subcontinent and Indochina. The generic name is derived from the Greek word μῖμος (mimos), an "actor" or "mime", and the feminine suffix -osa, "resembling", suggesting its 'sensitive leaves' which seem to 'mimic conscious life'.
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.
The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, are a large and agriculturally important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and their compound, stipulate leaves. The family is widely distributed, and is the third-largest land plant family in number of species, behind only the Orchidaceae and Asteraceae, with about 765 genera and nearly 20,000 known species.
Cercis is a genus of about 10 species in the subfamily Cercidoideae of the pea family Fabaceae. It contains small deciduous trees or large shrubs commonly known as redbuds in the USA. They are characterised by simple, rounded to heart-shaped leaves and pinkish-red flowers borne in the early spring on bare leafless shoots, on both branches and trunk ("cauliflory"). The genus contains ten species, native to warm temperate regions of North America, southern Europe, western and central Asia, and China.
Piptadenia is a genus of tropical shrubs and trees of the family Fabaceae. It includes 28 species native to the tropical Americas, ranging from central Mexico to southern Brazil and northwestern Argentina.
Mimosa diplotricha is a species of leguminous woody shrub native to the Neotropics. It is an invasive species and now has a pantropical distribution. It is commonly known as the giant sensitive plant, giant false sensitive plant, or nila grass.
Mimosa invisa is a species of leguminous woody shrub or vine native to South America. Mimosa invisa includes two subspecies, each with two varieties: The species is considered to be noxious and invasive in much of the United States.
Rupert Charles Barneby was a British-born self-taught botanist whose primary specialty was the Fabaceae (Leguminosae), the pea family, but he also worked on Menispermaceae and numerous other groups. He was employed by the New York Botanical Garden from the 1950s until shortly before his death.
Hydrochorea is a genus of flowering plants in the family Fabaceae. It includes 11 species native to Central and South America and west and west-central Africa. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.
Leucochloron is a genus of flowering plant in the family Fabaceae. It includes four species native to Brazil. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.
Macrosamanea is a genus of flowering plant in the legume family, Fabaceae. It includes 11 species of trees and shrubs native to northern South America. The genus is most diverse and numerous in the Amazon Basin, extending into the Orinoco basin and the Guianas. Typical habitat is tropical rain forest, mostly riparian and seasonally-flooded. Two species are native to seasonally-inundated wooded grassland (savanna) on sandy soils. The genus belongs to the mimosoid clade of the subfamily Caesalpinioideae.
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.
Entada is a genus of flowering plants in the family Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It consists of some 30 species of trees, shrubs and tropical lianas. About 21 species are known from Africa, six from Asia, two from the American tropics and one with a pantropical distribution. They have compound leaves and produce exceptionally large seedpods of up to 1.5 metres (4.9 ft) long. Their seeds are buoyant and survive lengthy journeys via rivers and ocean currents, to eventually wash up on tropical beaches.
Blanchetiodendron is a genus of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae. It contains a single species, Blanchetiodendron blanchetii, a shrub endemic to eastern Brazil. It ranges from Bahia to northeastern Minas Gerais states.
Falcataria is a genus of flowering plants in the family Fabaceae. It belongs to the monophyletic Mimosoid clade in the subfamily Caesalpinioideae. The genus has three species previously classified in the Falcataria section of the genus Paraserianthes by I.C. Neilsen. The distribution of these closely related species within the genus Falcataria links the wet tropics of north-east Australia to New Guinea, the Moluccas, Bismarck Archipelago, and the Solomon Islands east of Wallace's line similar to other plant taxa from the region.
Hesperalbizia is a genus of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae. The only species is Hesperalbizia occidentalis. It is native to Mexico and is known by the common name palo escopeta.
Samanea is a genus of flowering plants in the family Fabaceae. It includes four species of trees native to the tropical Americas, ranging from Belize to Paraguay, and to the Democratic Republic of the Congo in central Africa. Habitats include tropical moist evergreen and seasonally-dry deciduous forest, woodland, and wooded grassland. It belongs to the mimosoid clade of the subfamily Caesalpinioideae. The type species is Samanea saman from South America.
Sphinga prehensilis is a species of flowering plant in the legume family, Fabaceae. It is a perennial shrub endemic to Cuba. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.
Pityrocarpa is a genus of flowering plants in the family Fabaceae. It includes seven species of shrubs and small trees native to the tropical Americas, including western and southeastern Mexico, Guatemala and El Salvador, Venezuela and Guyana, Bolivia, and eastern Brazil. Native habitats include tropical coastal rain forest, gallery forest, secondary forest, woodland, wooded grassland (Cerrado), and thorn scrub (Caatinga). It belongs to the mimosoid clade of the subfamily Caesalpinioideae.
