Hedysareae is a tribe of plants in the subfamily Faboideae. Hedysareae species have loments, a type of modified legume that breaks apart at constrictions occurring between the segments of the seeds.
The tribe consists of the following genera: [1] [2] [3] [4]
Molecular phylogenetics have uncovered the following relationships: [2] [3] [4]

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.
Galegeae is a tribe in the flowering plant family Fabaceae, subfamily Faboideae. The tribe is found mostly in the northern hemisphere, but can also be found in Australia, Africa, and South America. Recent molecular phylogenetic work has determined that tribe Galegeae is paraphyletic, and that its members are scattered throughout the IR-lacking clade.
Crotalarieae is a tribe of flowering plants belonging to the family Fabaceae. It includes rooibos (Aspalathus linearis), harvested for sale as a tisane.
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.
The tribe Amorpheae is an early-branching clade within the flowering plant subfamily Faboideae or Papilionaceae. It is found from Mexico to Argentina. It was recently found to belong in a larger clade known informally as the dalbergioids sensu lato. This tribe is consistently resolved as monophyletic in molecular phylogenetic analyses. It is estimated to have arisen 36.9 ± 3.0 million years ago. A node-based definition for Amorpheae is: "the MRCA of Psorothamnus arborescens and Eysenhardtia orthocarpa." The tribe exhibits the following morphological synapomorphies: "epidermal glands throughout the plant body; dry, indehiscent fruits that are single-seeded; and terminal inflorescences."
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.
Orchideae is a tribe of orchids in the subfamily Orchidoideae. Historically, it was divided into 2 subtribes, Orchidinae and Habenariinae. The subtribe Orchidinae alone contains about 1,800 species. However, although some phylogenetic studies have established the monophyly of the subtribes, the generic boundaries are unclear, with many genera as traditionally circumscribed being paraphyletic or even polyphyletic. Species of genera such as Habenaria and Platanthera have been placed into both subtribes. A 2017 molecular phylogenetic study found that both subtribes did form clades, but did not formally recognize Habenariinae, because of missing genera and uncertainty over generic boundaries. The Asian species of Orchideae, in particular, have been subject to repeated changes of generic placement from 2012 onwards.
The inverted repeat-lacking clade(IRLC) is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae). Faboideae includes the majority of agriculturally-cultivated legumes. The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN. The clade is characterized by the loss of one of the two 25-kb inverted repeats in the plastid genome that are found in most land plants. It is consistently resolved in molecular phylogenies. The clade is predicted to have diverged from the other legume lineages 39.0±2.4 million years ago (in the Eocene). It includes several large, temperate genera such as AstragalusL., HedysarumL., MedicagoL., OxytropisDC., SwainsonaSalisb., and TrifoliumL..
The Cladrastis clade is a monophyletic clade of the flowering plant subfamily Faboideae that is found in eastern Asia and southern North America. It is consistently resolved in molecular phylogenies and is sister to the Meso-Papilionoideae. Evidence for the existence of this clade was first proposed based on morphological (floral), cytological, and biochemical evidence. It is predicted to have diverged from the other legume lineages 47.4±2.6 million years ago.
The Andira clade is a predominantly Neotropical, monophyletic clade of the flowering plant subfamily Faboideae. The members of this clade were formerly included in tribe Dalbergieae, but this placement was questioned due to differences in wood anatomy and fruit, seed, seedling, floral, and vegetative characters. Recent molecular phylogenetic evidence has shown that they belong to a unique evolutionary lineage. It is predicted to have diverged from the other legume lineages in the late Eocene).
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 dalbergioids are an early-branching monophyletic clade of the flowering plant subfamily Faboideae or Papilionaceae. They are pantropical, particularly being found in the neotropics and sub-Saharan Africa. This clade is consistently resolved as monophyletic in molecular phylogenetic analyses. It is estimated to have arisen 55.3 ± 0.5 million years ago. A node-based definition for the dalbergioids is: "The least inclusive crown clade that contains Amorpha fruticosaL. 1753 and Dalbergia sissooRoxb. ex DC. 1825." Indehiscent pods may be a morphological synapomorphy for the clade.
The tribe Caesalpinieae is one of the subdivisions of the plant family Fabaceae: subfamily Caesalpinioideae.
Meso-Papilionoideae is a monophyletic clade of the flowering plant subfamily Faboideae that includes the majority of papilionoid legumes. This clade is consistently resolved in molecular phylogenies. It contains many agronomically important genera, including Arachis (peanut), Cicer (chickpea), Glycine (soybean), Medicago (alfalfa), Phaseolus, Trifolium (clover), Vicia (vetch), and Vigna.
Corethrodendron is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae.
Sulla is a genus of flowering plants in the legume family, Fabaceae. It includes eight species of annual herbs native to the Mediterranean Basin, including southern Europe, North Africa, and western Asia. They grow in dry Mediterranean-climate shrubland, bushland, thicket, and grassland and in semi-desert. The genus belongs to subfamily Faboideae.
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
