Ormosia is a genus of legumes (family Fabaceae). The more than 100 living species, mostly trees or large shrubs, are distributed throughout the tropical regions of the world, some extending into temperate zones, especially in East Asia. A few species are threatened by habitat destruction, while the Hainan ormosia (Ormosia howii) is probably extinct already.
Plants in this genus are commonly known as horse-eye beans or simply ormosias, and in Spanish by the somewhat ambiguous term "chocho". The scientific name Ormosia is a nomen conservandum , overruling Toulichiba which is formally rejected under the International Code of Nomenclature for algae, fungi, and plants . [1]
The seeds of these plants are poisonous if eaten, but often look pretty, with bright colors and decorative patterns reminiscent of an eye; the common name "horse-eye beans" refers to these seeds. They resemble the seeds of Abrus , snoutbeans (Rhynchosia), and Adenanthera , but are much larger than the former two. In particular those of Ormosia coccinea are often used for jewelry and other decorative purposes, or as good luck charms.[ citation needed ] The seeds float and are occasionally found as "sea beans".
Otherwise, Ormosia wood is used as timber or firewood. Some species, for example Ormosia nobilis , are also used in folk medicine. [2]
8 dehiscent seed pod fossils of one Ormosia species from the middle Eocene epoch have been examined from Warman clay pit in Weakley County, while 52 fossil leaflets of two Ormosia species have been described from Warman, New Lawrence and Lamkin clay pits in Weakley and Henry Counties, Tennessee, United States.

Ormosia comprises the following species: [4] [5] [6]
The status of the following species is unresolved: [6] [ verification needed ]
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
Dalbergia is a large genus of small to medium-size trees, shrubs and lianas in the pea family, Fabaceae, subfamily Faboideae. It was recently assigned to the informal monophyletic Dalbergia clade : the Dalbergieae. The genus has a wide distribution, native to the tropical regions of Central and South America, Africa, Madagascar and southern Asia.
Bauhinia is a large genus of flowering plants in the subfamily Cercidoideae and tribe Bauhinieae, in the large flowering plant family Fabaceae, with a pantropical distribution. The genus was named after the Bauhin brothers Gaspard and Johann, Swiss-French botanists.
Styphnolobium is a small genus of three or four species of small trees and shrubs in the subfamily Faboideae of the pea family Fabaceae, formerly included within a broader interpretation of the genus Sophora. It was recently assigned to the unranked, monophyletic Cladrastis clade. 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.
Sophora is a genus of about 45 species of small trees and shrubs in the pea family Fabaceae. The species have a pantropical distribution. The generic name is derived from sophera, an Arabic name for a pea-flowered tree.
The plant tribe Phaseoleae is one of the subdivisions of the legume subfamily Faboideae, in the unranked NPAAA clade. This group includes many of the beans cultivated for human and animal food, most importantly from the genera Glycine, Phaseolus, and Vigna.
Cynometra is genus of tropical forest trees with a pantropical distribution. It is particularly important as a forest component in west Africa and the neotropics. Cynometra alexandri (muhimbi) is a familiar timber tree of central and east Africa. The genus is a member of the subfamily Detarioideae. It has been suggested that Cynometra is polyphyletic and is in need of revision. In 2019, beside description of 4 new species, Aleksandar Radosavljevic suggested that the species formerly recognized as Maniltoa should be included in this genus and some of the mainland tropical African species excluded from this genus because of their jointed pedicels and dehiscent fruits.
Andira is a genus of flowering plants in the legume family, Fabaceae. It is distributed in the tropical Americas, except for A. inermis, which also occurs in Africa. It was formerly assigned to the tribe Dalbergieae, but recent molecular phylogenetic evidence has placed it in a unique clade named the Andira clade.
Machaerium is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. It contains the following species:
Poecilanthe is a genus of flowering plants in the family Fabaceae.
Sclerolobium is a genus of 40 species of flowering plants in the Leguminosae. It has been suggested that it should be merged with Tachigali.
Leptolobium is a small Neotropical genus of plants in the family Fabaceae, with ten species currently recognized. With the exception of Leptolobium panamense, which occurs in tropical forests from northwestern South America to Mexico, all species of Leptolobium are restricted to South America and most diverse in Brazil. Most Leptolobium species have been traditionally included in AcosmiumSchott (Fabaceae), but both genera have been recently distinguished based on several vegetative and reproductive traits.
Luetzelburgia is a genus of flowering plants in the legume family, Fabaceae. It 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.
Macropsychanthus is a genus of flowering plants in the legume family, Fabaceae. It belongs to the tribe Diocleae, subfamily Faboideae.
The tribe Desmodieae is one of the subdivisions of the plant family Fabaceae. It is composed of two subtribes, Desmodiinae and Lespedezinae. Recent phylogenetics has this tribe nested within tribe Phaseoleae.
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 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.
Lasiobema is a genus of flowering plants in the legume family, Fabaceae, most of which are lianas. It belongs to the subfamily Cercidoideae. It was recently synonymized with Phanera on the basis of morphology, but this move has been questioned.
Phanera is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Cercidoideae. This genus differs from Bauhinia in being vines or lianas, generally with tendrils and a lobed rather than spathaceous calyx, and from Schnella in having only three fertile stamens rather than ten, and being native to the Indomalayan realm and the Australasian realm rather than the Americas. The subsection Corymbosae was recently segregated into a new genus, Cheniella. It has been suggested that the genus Lasiobema should be reduced to a section within Phanera.
