Cassia is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae. Species are known commonly as cassias. The genus includes 37 species and has a pantropical distribution. Species of the genera Senna and Chamaecrista were previously included in Cassia. Cassia now generally includes the largest species of the legume subtribe Cassiinae, usually mid-sized to tall trees.
Combretum, the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and tropical America. Though somewhat reminiscent of willows (Salix) in their habitus, they are not particularly close relatives of these.
Calliandra is a genus of flowering plants in the pea family, Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It contains about 140 species that are native to tropical and subtropical regions of the Americas.
Menispermaceae is a family of flowering plants. The alkaloid tubocurarine, a neuromuscular blocker and the active ingredient in the 'tube curare' form of the dart poison curare, is derived from the South American liana Chondrodendron tomentosum. Several other South American genera belonging to the family have been used to prepare the 'pot' and 'calabash' forms of curare. The family contains 78 genera with some 440 species, which are distributed throughout low-lying tropical areas with some species present in temperate and arid regions.
Anomospermum is a genus of flowering plants in the family Menispermaceae. It consists of five species from tropical America, ranging from Nicaragua to southern Brazil.
Pouteria is a genus of flowering trees in the gutta-percha family, Sapotaceae. The genus is widespread throughout the tropical Americas, with outlier species in Cameroon and Malesia. It includes the canistel, the mamey sapote, and the lucuma. Commonly, this genus is known as pouteria trees, or in some cases, eggfruits.
Abuta is a genus in the flowering plant family Menispermaceae, of about 32 species, native to tropical Central and South America.
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.
Odontocarya is a plant genus in the family Menispermaceae. It includes 38 species native to the tropical Americas, ranging from southern Mexico to northern Argentina.
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.
Cojoba is a genus of flowering plants in the family Fabaceae. It includes 15 species, which range through the tropical Americas from northern Mexico through Central America and the Caribbean to Bolivia and northern Brazil. from
Lecointea is a genus of flowering plants in the family Fabaceae. It contains seven species native to the tropical Americas.
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.
Hyperbaena is a genus of plants in family Menispermaceae. It includes 23 species native to the tropical Americas, ranging from Cuba and southern Mexico to northeastern Argentina.
Ebenopsis is a genus of flowering plants in the family Fabaceae. It includes three species native to Mexico and Texas.
Curarea is a genus of flowering plants in the family Menispermaceae, found in tropical parts of Central and South America. They are dioecious lianas, with at least some species producing toxic compounds such as curare.
Morisonia is a genus of flowering plants in the family Capparaceae, found across the Americas from the United States to Argentina. They are typically shrubs or small trees. The genus was recently enlarged with New World Capparis species due to existing taxonomic instability.
Sciadotenia is a genus of flowering plants belonging to the family Menispermaceae.
