Styphnolobium is a genus of flowering plants in the pea family, Fabaceae. It includes nine species of small trees and shrubs native to China and to the Americas, from the southern United States to Colombia. [1] It belongs to subfamily Faboideae, and was formerly included within a broader interpretation of the genus Sophora . It was recently assigned to the unranked, monophyletic Cladrastis clade. [2] [3] [4] They differ from the genus Calia (mescalbeans) in having deciduous leaves and flowers in axillary, not terminal, racemes. The leaves are pinnate, with 9–21 leaflets, and the flowers in pendulous racemes similar to those of the black locust. Necklacepod is a common name for plants in this genus. [5]
From Greek styphno-, stryphno- "sour, astringent" and lobion "pod", because of the fresh pods' pulp taste. [6]
Styphnolobium comprises the following species: [7] [8] [9]

Styphnolobium japonicum (Chinese: 槐; pinyin: huái; formerly Sophora japonica) is one of the 50 fundamental herbs used in traditional Chinese medicine.
The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family.
Cladrastis (yellowwood) is a genus of flowering plants in the family Fabaceae. It includes four species, three native to eastern Asia and one to southeastern North America.
Styphnolobium japonicum, the Japanese pagoda tree is a species of deciduous tree in the subfamily Faboideae of the pea family Fabaceae.
Crotalarieae is a tribe of flowering plants belonging to the family Fabaceae. It includes rooibos (Aspalathus linearis), which is harvested for sale as a tisane.
Amphimas is a small genus of flowering plants in the family Fabaceae. It belongs to the subfamily Faboideae. It is a west African tree used for medicine and for wood. Amphimas was traditionally assigned to the tribe Sophoreae; however, recent molecular phylogenetic analyses reassigned Amphimas into an unspecified position in the Meso-Papilionoideae.
Leucomphalos is a genus of flowering plants in the legume family, Fabaceae. It contains a single species, Leucomphalos capparideus, a climbing perennial shrub native to the Guineo-Congolian forest of Nigeria, Cameroon, Equatorial Guinea, Gabon, and the Gulf of Guinea Islands. It belongs to the subfamily Faboideae. Leucomphalos was traditionally assigned to the tribe Sophoreae; however, recent molecular phylogenetic analyses reassigned Leucomphalos to the Baphieae tribe.
Luetzelburgia is a genus of flowering plants in the legume family, Fabaceae. It includes 14 species of trees and shrubs native to Brazil, Bolivia, and Colombia. Typical habitat is seasonally-dry tropical lowland woodland and wooded grassland, and occasionally lowland rain forests. The genus belongs to the subfamily Faboideae. It was traditionally assigned to the tribe Sophoreae, mainly on the basis of flower morphology; recent molecular phylogenetic analyses assigned Luetzelburgia into an informal, monophyletic clade called the "vataireoids". Keys for the different species of Luetzelburgia have been published.
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 Dalbergieae is an early-branching clade within the flowering plant subfamily Faboideae. Within that subfamily, it belongs to an unranked clade called the dalbergioids. It was recently revised to include many genera formerly placed in tribes Adesmieae and Aeschynomeneae and to be included in a monophyletic group informally known as the dalbergioids sensu lato. The members of this tribe have a distinctive root nodule morphology, often referred to as an "aeschynomenoid" or "dalbergioid" nodule.
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 vataireoids are an early-branching monophyletic clade of the flowering plant subfamily Faboideae that are mostly found in northern South America, primarily Brazil.
The non-protein amino acid-accumulating clade, also known as the Canavanine-accumulating clade is a clade of the flowering plant subfamily Faboideae that includes the majority of agriculturally-cultivated legumes. It is characterized by the accumulation of the non-proteinogenic amino acid canavanine in the seeds—a deterrent against herbivory. This phylogenetic trait was first recognized in the early 1980s. This clade is consistently resolved in molecular phylogenies. It contains many economically important genera, including Cicer, Glycine, Medicago, Phaseolus, Trifolium, Vicia, and Vigna.
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 tribe Ormosieae is one of the subdivisions of the plant family Fabaceae, primarily found in tropical regions of the Americas, but also in southeast Asia and northern Australia. The members of this tribe were formerly included in tribe Sophoreae, but were recently circumscribed into a new tribe. 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 tentatively identified: "mostly dehiscent pods with woody valves" and "tufts of minute colleter-like glands in the axils of bract and bracteoles". Like other genistoids, members of tribe Ormosieae are known to produce quinolizidine alkaloids.
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.
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.
