Sesbania is a genus of flowering plants in the pea family, Fabaceae, and the only genus found in tribe Sesbanieae. Riverhemp is a common name for plants in this genus. [2] Notable species include the rattlebox ( Sesbania punicea ), spiny sesbania ( Sesbania bispinosa ), and Sesbania sesban , which is used in cooking. Plants of this genus, some of which are aquatic, can be used in alley cropping to increase the soil's nitrogen content. The species of rhizobia responsible for nitrogen fixation in Sesbania rostrata is Azorhizobium caulinodans .
Some 60 species are currently accepted, with about 39 still unresolved. The genus is native to tropical and subtropical regions around the world, in the Americas from the southern United States to northern Argentina, in sub-Saharan Africa, in southern Asia, and in New Guinea, Australia, and the Pacific. [1] The largest number of species are found in Africa, and the remainder in Australia, Hawaii, and Asia. [3]
Fossil seed pods from the upper Oligocene resembling Sesbania have been found in the Hungarian locality of Eger Wind-brickyard. The fossil species grew in a swampy and riparian environment. [4]
60 species are accepted, [1] organized into three sections: [5]
Modern molecular phylogenetics suggest the following relationships between the species of Sesbania: [5]
The Celastraceae are a family of 98 genera and 1,350 species of herbs, vines, shrubs and small trees, belonging to the order Celastrales. The great majority of the genera are tropical, with only Celastrus, Euonymus and Maytenus widespread in temperate climates, and Parnassia (bog-stars) found in alpine and arctic climates.
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.
Cissus is a genus of approximately 350 species of lianas in the grape family (Vitaceae). They have a cosmopolitan distribution, though the majority are to be found in the tropics.
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.
Pluchea is a genus of flowering plants in the tribe Inuleae within the family Asteraceae. Members of this genus might be known as camphorweeds, plucheas, or less uniquely fleabanes. Some, such as P. carolinensis and P. odorata, are called sourbushes. There are plants of many forms, from annual and perennial herbs to shrubs and trees, and there is variation in the morphology of leaves, flowers, and fruits.
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.
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.
