Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.
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.
In 1984, the International Organization for Succulent Plant Study set up a working party, now called the International Cactaceae Systematics Group, to produce a consensus classification of the cactus family, down to the level of genus. Their classification has been used as the basis for systems published since the mid-1990s. Treatments in the 21st century have generally divided the family into around 125–130 genera and 1,400–1,500 species, which are then arranged in a number of tribes and subfamilies. However, subsequent molecular phylogenetic studies have shown that a very high proportion of the higher taxa are not monophyletic, i.e. they do not contain all of the descendants of a common ancestor. As of August 2023, the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010.
Pereskiopsis is a genus of cactus in the subfamily Opuntioideae. Unlike typical cacti, it has persistent fleshy leaves. The genus name refers to its resemblance to the genus Pereskia. Most species are found in Mexico south through Guatemala to Honduras, with one species in Bolivia. The incorrect spelling Peireskiopsis has also been used.
Leucaena is a genus of flowering plants in the mimosoid clade of the subfamily Caesalpinioideae of the family Fabaceae. It contains about 24 species of trees and shrubs, which are commonly known as leadtrees. They are native to the Americas, ranging from Texas in the United States south to Peru. The generic name is derived from the Greek word λευκός (leukos), meaning "white," referring to the flowers.
Opuntioideae is a subfamily of the cactus family, Cactaceae. It contains 15 genera divided into five tribes. The subfamily encompasses roughly 220–250 species, and is geographically distributed throughout the New World from Canada, to Argentina. Members of this subfamily have diverse habits, including small geophytes, hemispherical cushions, shrubs, trees, and columnar cacti consisting of indeterminate branches or determinate terete or spherical segments.
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.
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 belongs to the mimosoid clade of the subfamily Caesalpinioideae.
Havardia is a genus of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae. It includes five species of trees native to the Americas, ranging from Texas and northern Mexico through Central America to Colombia and Venezuela. Typical habitats include warm-temperate and tropical seasonally-dry woodland, wooded grassland, and desert thorn scrub, typically below 450 meters elevation.
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.
Mariosousa is a genus of 13 species of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae. Members of this genus were formerly considered to belong to the genus Acacia.
Calliandropsis is a genus of flowering plants in the family Fabaceae. It contains a single species, Calliandropsis nervosa, a shrub native to northeastern, central, and southern Mexico. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.
The Hylocereeae are a tribe of cacti. Most are found in the tropical forests of Central and northern South America, and are climbers or epiphytes, unlike most cacti. The tribe includes between six and eight genera in different circumscriptions. The plants known as "epiphyllum hybrids" or "epiphyllums", widely grown for their flowers, are hybrids of species within this tribe, particularly Disocactus, Pseudorhipsalis and Selenicereus, less often Epiphyllum, in spite of the common name.
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.
Erythrostemon is a genus of flowering plants in the legume family, Fabaceae. Its native range is tropical & subtropical America.
Guilandina is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Caesalpinioideae and tribe Caesalpinieae.
Coulteria is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Caesalpinioideae. It includes ten species native the tropical Americas, from northern Mexico through Central America to Colombia and Venzezuela, including Cuba and Jamaica.
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.
Hatiora cylindrica is a species of often epiphytic cactus in the tribe Rhipsalideae within the subfamily Cactoideae. It is native to east Brazil, where it grows in a variety of habitats, including moist forest, dunes and coastal rocks.
