Lespedeza

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.

Name of the plant
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 ), 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.

Despeleza is a synonym of Lespedeza, and this name is derived from a taxonomic anagram.

Cultivation and uses
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.
