Lespedeza is a genus of some 45 species (including nothospecies) of flowering plants in the pea family (Fabaceae), commonly known as bush clovers or (particularly East Asian species) Japanese clovers (hagi). The genus is native to warm temperate to subtropical regions of eastern North America, eastern and southern Asia and Australasia.
These shrubby plants or trailing vines belong to the "typical" legumes (Faboideae), with the peas and beans, though they are part of another tribe, the Desmodieae. Therein, they are treated as type genus of the smaller subtribe Lespedezinae, which unites the present genus and its presumed closest relatives, Campylotropis and Kummerowia .
According to American botanist Asa Gray (1810–1888), the Lespedeza owes its name to governor of East Florida Vicente Manuel de Céspedes (1784–1790; who, through a letter, allowed botanist André Michaux to explore East Florida in search of new species of plants, where Michaux found Lespedeza [3] ), but when Céspedes wrote the letter, at the beginning of it, the name of Céspedes was changed to "Zespedez". So, when Michaux's book Flora Boreali-Americana of 1802 was printed, the name "Céspedes" to refer to the plant was written as "Lespedez", the word from which the current name of the plant was derived. [4] [3]
Despeleza is a synonym of Lespedeza, and this name is derived from a taxonomic anagram. [5]
Some species are grown as garden or ornamental plants, and are used as a forage crops, notably in the southern United States, and as a means of soil enrichment and for prevention of erosion. In some areas, certain species are invasive. Lespedeza, like other legumes, have root nodules that harbor bacteria capable of nitrogen fixation from the air into a soil-bound form that can be taken up by other plants. Growers can take advantage of this process by putting the plants in their fields to release nitrogen, so they can use less fertilizer.
L. bicolor leaves and roots contain l-methoxy-N,N-dimethyltryptamine (lespedamine), as well as related Nω,Nω-dimethyltryptamines and their oxides, as well as some bufotenin. [6]
The species and nothospecies recognized in Lespedeza include: [1]
Some species formerly in this genus that are now placed elsewhere, typically in the Lespedezinae, for example, in genus Campylotropis . These include: [8]
Vigna is a genus of plants in the legume family, Fabaceae, with a pantropical distribution. It includes some well-known cultivated species, including many types of beans. Some are former members of the genus Phaseolus. According to Hortus Third, Vigna differs from Phaseolus in biochemistry and pollen structure, and in details of the style and stipules.
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.
Astilbe is a genus of 18 species of rhizomatous flowering plants within the family Saxifragaceae, native to mountain ravines and woodlands in Asia and North America. Some species are known by the common names false goat's beard and false spirea.
Desmodium is a genus of plants in the legume family Fabaceae, sometimes called tick-trefoil, tick clover, hitch hikers or beggar lice. There are dozens of species and the delimitation of the genus has shifted much over time. Species are distributed widely – from Quebec to northern Argentina in the Americas, across northern and southern tropical Africa, in the southern Arabian Peninsula, in Myanmar and Thailand, New Guinea, and northern and eastern Australia.
Lespedeza thunbergii is a species of flowering plant in the legume family known by the common names Thunberg's bushclover, Thunberg's lespedeza, and shrub lespedeza. It is native to the eastern Himalayas, China, Korea, and Japan.
Phanera is a genus of flowering plants in the legume subfamily Cercidoideae and the tribe Bauhinieae. 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.
Eriocapitella is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are native to Asia. The generic name Eriocapitella roughly translates to "growing in a small woolly head", which refers to the hairy ovary and fruit of some members of the genus. Cultivated plants are commonly known as fall-blooming anemones.
