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.
Caesalpinioideae is a botanical name at the rank of subfamily, placed in the large family Fabaceae or Leguminosae. Its name is formed from the generic name Caesalpinia. It is known also as the peacock flower subfamily. The Caesalpinioideae are mainly trees distributed in the moist tropics, but include such temperate species as the honeylocust and Kentucky coffeetree. It has the following clade-based definition:
The most inclusive crown clade containing Arcoa gonavensisUrb. and Mimosa pudicaL., but not Bobgunnia fistuloides(Harms) J. H. Kirkbr. & Wiersema, Duparquetia orchidaceaBaill., or Poeppigia proceraC.Presl
The subfamily Detarioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees, some of which are used for timber or have ecological importance. The subfamily consists of 84 genera, most of which are native to Africa and Asia. Pride of Burma and tamarind are two of the most notable species in Detarioideae. It has the following clade-based definition:
The most inclusive crown clade containing Goniorrhachis marginataTaub. and Aphanocalyx cynometroidesOliv., but not Cercis canadensisL., Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J. H. Kirkbr. & Wiersema.
The genus Tylosema is in the plant family Fabaceae and encompasses four accepted species of perennial legumes native to southern and central Africa. These are semi-woody viniferous plants broadly distributed from Sudan and Ethiopia south to Angola and South Africa. Coetzer and Ross originally described four Tylosema species:
Gigasiphon is a genus of plants in the family Fabaceae. The genus is circumscribed is defined by "a long-tubular hypanthium, an arborescent habit, and a calyx divided into two lobes." It includes five species native to eastern Africa, Madagascar, the Philippines, New Guinea, and Lesser Sunda Islands.
Orphanodendron is a genus of legume in the legume family, Fabaceae. It includes two species of trees native to Colombia, which grow in tropical lowland forest. The genus is in subfamily Faboideae.
Cercidoideae is a subfamily in the pea family, Fabaceae. Well-known members include Cercis (redbuds), including species widely cultivated as ornamental trees in the United States and Europe, Bauhinia, widely cultivated as an ornamental tree in tropical Asia, and Tylosema, a semi-woody genus of Africa. The subfamily occupies a basal position within the Fabaceae and is supported as monophyletic in many molecular phylogenies. At the 6th International Legume Conference, the Legume Phylogeny Working Group proposed elevating the tribe Cercidae to the level of subfamily within the Leguminosae (Fabaceae). The consensus agreed to the change, which was fully implemented in 2017. It has the following clade-based definition:
The most inclusive crown clade containing Cercis canadensisL. and Bauhinia divaricataL. but not Poeppigia proceraC.Presl, Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J.H.Kirkbr. & Wiersema.
Brenierea insignis is a species of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Cercidoideae and is the only member of the genus Brenierea. It is endemic to Madagascar.
Lysiphyllum is a genus of flowering plants in the legume family, Fabaceae. It includes nine species of trees, semi-scandent shrubs, and lianas which range from India through Southeast Asia to Australasia. Typical habitats include seasonally-dry tropical forest and woodland, vine thickets, Brigalow and Gidgee scrubland, floodplains, alluvial flats, tidal forest, mangroves, river and stream banks, and occasionally dunes and coral islets. They can grow on diverse soils including calcareous, granitic, and basaltic.
Piliostigma is a genus of flowering plants in the legume family, Fabaceae. It includes five species of small deciduous trees native to sub-Saharan Africa, the Indian subcontinent, Indochina, Java, the Philippines, and northern Australia. It belongs to the subfamily Cercidoideae and the tribe Bauhinieae. It is dioecious, with male and female flowers on separate plants.
The tribe Brongniartieae is one of the subdivisions of the plant family Fabaceae, primarily found in tropical regions of the Americas and in Australia The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses. The tribe does not currently have a node-based definition, but morphological synapomorphies have been identified:
"stamens united by filaments in an adaxially open tube; anthers alternately long and basifixed, short and versatile; anther connective inconspicuous; septa present between seeds in pods; aril lateral lobe present and fitting into heel of funicle; fine red glandular processes present in axils; and pollen tricolporate with opercula and no definite endoaperture."
The tribe Indigofereae is a subdivision of the plant family Fabaceae. It is consistently recovered as a monophyletic clade in molecular phylogenies. The Indigofereae arose 30.0 ± 3.3 million years ago.
The tribe Sophoreae is one of the subdivisions of the plant family Fabaceae. Traditionally this tribe has been used as a wastebasket taxon to accommodate genera of Faboideae which exhibit actinomorphic, rather than zygomorphic floral symmetry and/or incompletely differentiated petals and free stamens. Various morphological and molecular analyses indicated that Sophoreae as traditionally circumscribed was polyphyletic. This led to a re-circumscription of Sophoreae, which resulted in the transfer of many genera to other tribes. This also necessitated the inclusion of two former tribes, Euchresteae and Thermopsideae, in the new definition of Sophoreae. Tribe Sophoreae, as currently circumscribed, consistently forms a monophyletic clade in molecular phylogenetic analyses. The Sophoreae arose 40.8 ± 2.4 million years ago.
The tribe Swartzieae is an early-branching monophyletic clade of the flowering plant subfamily Faboideae or Papilionaceae. Traditionally this tribe has been used as a wastebasket taxon to accommodate genera of Faboideae which exhibit actinomorphic, rather than zygomorphic floral symmetry and/or incompletely differentiated petals and free stamens. It was recently revised and most of its genera were redistributed to other tribes. Under its new circumscription, this clade is consistently resolved in molecular phylogenies. Members of this tribe possess "non-papilionate swartzioid flowers[…]largely characterized by a tendency to lack petals combined with a profusion and elaboration of free stamens" and a "lack of unidirectional order in the initiation of the stamens". They also have "complete or near complete fusion of sepals resulting from intercalary growth early in development, relatively numerous stamens, and a single or no petal, with other petals not at all apparent in development." The tribe is predicted to have diverged from the other legume lineages 48.9±2.8 million years ago.
The robinioids are one of the four major clades in subfamily Faboideae of the plant family Fabaceae (Leguminosae). It is composed of the traditional tribes Loteae, Sesbanieae and Robinieae. It is a large and important clade that is distributed in mostly temperate areas. Species in this clade share a unique determinate root nodule structure. The clade is predicted to have diverged from the other legume lineages 48.3±1.0 million years ago.
The Genistoids are one of the major radiations in the plant family Fabaceae. Members of this phylogenetic clade are primarily found in the Southern hemisphere. Some genera are pollinated by birds. The genistoid clade is consistently resolved as monophyletic in molecular phylogenetic analyses. It is estimated to have arisen 56.4 ± 0.2 million years ago. A node-based definition for the genistoids is: "the MRCA of Poecilanthe parviflora and Lupinus argenteus." One morphological synapomorphy has been tentatively identified: production of quinolizidine alkaloids. Some genera also accumulate pyrrolizidine. A new genus, to be segregated from Clathrotropis, has also been proposed to occupy an undetermined position within the genistoid clade.
The tribe Caesalpinieae is one of the subdivisions of the plant family Fabaceae: subfamily Caesalpinioideae.
The subfamily Dialioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees and shrubs. The subfamily consists of 17 genera, which are widespread throughout the tropics. It has the following clade-based definition:
The most inclusive crown clade containing Poeppigia proceraC.Presland Dialium guianense(Aubl.) Sandwith, but not Cercis canadensisL., Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J. H. Kirkbr. & Wiersema
Piliostigma malabaricum is a small tree species in the family Fabaceae. It was previously placed in the genus Bauhinia, but names changed with reorganisation of the subfamily Cercidoideae and the tribe Bauhinieae.
