Pithecellobium is a genus of flowering plants in the legume family, Fabaceae. The generic name is derived from the Greek words πιθηκος (pithekos), meaning "ape" or "monkey," and ελλοβιον (ellobion), meaning "earring," which refers to the coiled shape of the fruit pods.Plants of the genus are known generally as blackbeads.
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma ("seed").
A legume is a plant in the family Fabaceae, or the fruit or seed of such a plant. Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include alfalfa, clover, peas, chickpeas, lentils, lupin bean, mesquite, carob, soybeans, peanuts and tamarind. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces on two sides. A common name for this type of fruit is a pod, although the term "pod" is also applied to a number of other fruit types, such as that of vanilla and of the radish.
There are about 75 species in the genus:
George Bentham was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century".
Paul Carpenter Standley was an American botanist.
Pithecellobium decandrum is a species of flowering plant in the legume family, Fabaceae. It is endemic to Brazil, where it occurs in the forests of the Amazon River valley and along its tributaries.
Many species now in the genera Albizia and Abarema were formerly classified in Pithecellobium. Other species previously included:
Albizia is a genus of more than 160 species of mostly fast-growing subtropical and tropical trees and shrubs in the subfamily Mimosoideae of the family Fabaceae. The genus is pantropical, occurring in Asia, Africa, Madagascar, America and Australia, but mostly in the Old World tropics. In some locations, some species are considered weeds.
Abarema is a neotropical genus of large trees in the legume family (Fabaceae). They grow from Mexico to Bolivia. Most of the species can be found in the Amazon Basin and the Guyana Highlands. They have a deep-green fernlike foliage, with bipinnately compound leaves.
Archidendron bigeminum is a tree species in the legume family (Fabaceae). It is found in India and Sri Lanka. It is known as "Kalitiya - කලටිය" in Sinhala people.
Chloroleucon foliolosum is a tree species in the legume family (Fabaceae). It is found in Argentina, Brazil and Bolivia.
Zygia cognata is a tree species in the legume family (Fabaceae). It is found in Belize, Guatemala, and Honduras.
The Mimosoideae are trees, herbs, lianas, and shrubs that mostly grow in tropical and subtropical climates. They comprise a clade, previously placed at the subfamily or family level in the flowering plant family Fabaceae (Leguminosae). In previous classifications, Mimosoideae refers to what was formerly considered the tribe Mimoseae. Characteristics include flowers in radial symmetry with petals that are valvate in bud, and have numerous showy, prominent stamens. Mimosoideae comprise about 40 genera and 2,500 species.
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.
Cassia is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae. Species are known commonly as cassias. Cassia is also the English common name of some species in the genus Cinnamomum of the family Lauraceae. Species of the genera Senna and Chamaecrista were previously included in Cassia. Cassia now generally includes the largest species of the legume subtribe Cassiinae, usually mid-sized trees.
Leucaena is a genus of flowering plants in the mimosoid clade of the subfamily Caesalpinioideae of the legume 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.
Sideroxylon is a genus of trees in the family Sapotaceae described as a genus by Linnaeus in 1753. They are collectively known as bully trees. The generic name is derived from the Greek words σιδηρος (sideros), meaning "iron", and ξύλον (xylon), meaning "wood."
Piptadenia is a genus of tropical shrubs and trees of the legume family.
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.
Brownea is a genus of about 30 species in the family Fabaceae, subfamily Detarioideae. The genus is native to tropical regions of the Americas. The species are shrubs and trees growing to 20 m tall.
Machaerium is a genus of legume in the Fabaceae family, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. It contains the following species:
Pithecellobium pithecolobioides, known as Granadillo de Río, is a tree species in the legume family (Fabaceae).
Tachigali is a flowering plant genus in the legume family (Fabaceae) that contains 54 species.
Enterolobium is a genus of 12 species of flowering plants in the family Fabaceae, native to tropical and warm-temperate regions of the Americas. They are medium-sized to large trees.
Remijia is a genus of flowering plants in the family Rubiaceae. Within the family, it is a member of the subfamily Cinchonoideae and the tribe Cinchoneae.
Citharexylum is a genus of flowering plants in the verbena family, Verbenaceae. It contains shrub and tree species commonly known as fiddlewoods or zitherwoods. They are native to the Americas, ranging from southern Florida and Texas in the United States to Argentina. The highest diversity occurs in Mexico and the Andes. The generic name is derived from the Greek words κιθάρα (kithara), meaning "lyre", and ξύλον (xylon), meaning "wood," referring to the use of the wood in the sounding boards of string instruments. Several species, especially C. caudatum and C. spinosum, are cultivated as ornamentals.
Schnella is a genus of flowering plants in the legume family, Fabaceae. It belongs to the sub family Cercidoideae.
Libidibia is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Caesalpinioideae.
