Clover, also called trefoil, are plants of the genus Trifolium, consisting of about 300 species of flowering plants in the legume family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 centimetres (12 in) tall. The leaves are trifoliate, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include Melilotus and Medicago.
Pterocarpus is a pantropical genus of trees in the family Fabaceae. It belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic Pterocarpus clade within the Dalbergieae. Most species of Pterocarpus yield valuable timber traded as padauk, usually pronounced or ; other common names are mukwa or narra. The west African species may be traded as African rosewood. P. santalinus also yields the most precious red sandalwood in China known as Zitan. The wood from the narra tree and the Burmese padauk tree is marketed as amboyna when it has grown in the burl form. The scientific name is Latinized Ancient Greek and means "wing fruit", referring to the unusual shape of the seed pods in this genus.
Brachystegia is a genus of tree of the subfamily Detarioideae that is native to tropical Africa.
Combretum, the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and tropical America. Though somewhat reminiscent of willows (Salix) in their habitus, they are not particularly close relatives of these.
Indigofera is a large genus of over 750 species of flowering plants belonging to the pea family Fabaceae. They are widely distributed throughout the tropical and subtropical regions of the world.
Olearia, most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple.
Tephrosia is a genus of flowering plants in the family Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions.
Aeschynomene is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. They are known commonly as jointvetches. They range across tropical and subtropical regions of the Americas, sub-Saharan Africa, south, southeast, and east Asia, and Australia. These legumes are most common in warm regions and many species are aquatic.
Piscidia is a genus of flowering plants in subfamily Faboideae of the family Fabaceae. It includes seven species of trees, and rarely shrubs, native to the tropical Americas, ranging from northern Mexico and Florida through Central America and the Caribbean to Venezuela and Peru. Typical habitats include seasonally-dry tropical forest, woodland, and bushland, often on rocky hills, with some species restricted to limestone substrates.
Vittadinia is a genus of Australian and New Zealand plants in the tribe Astereae within the family Asteraceae.
Triumfetta is a genus of plants in the family Malvaceae. Burbark is a common name for plants in this genus.
Mezoneuron is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Caesalpinioideae and the tribe Caesalpinieae.
