Lespedeza is a genus of some 40 species (including nothospecies) of flowering plants in the pea family (Fabaceae), commonly known as bush clovers or (particularly East Asian species) Japanese clovers. The genus is native to warm temperate to subtropical regions of eastern North America, eastern and southern Asia and Australasia.

Lespedeza bicolor is often grown as ornamental

These shrubby plants or trailing vines belong to the "typical" legumes (Faboideae) like peas and beans, though within these 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

Cultivation and uses[link]

Some species are grown as garden or ornamental plants, and/or are used as a forage crops, notably in the southern United States, and as a means of soil enrichment and for prevention of erosion. Some are invasive species in some areas. Lespedeza are collectively classified as legumes, meaning that their roots harbor bacteria capable of nitrogen fixation from the air into a soil-bound form that can be taken up by other plants (thereby reducing fertilizer input costs).

L. bicolor leaves and roots contain l-methoxy-N,N-dimethyltryptamine (lespedamin), as well as related N^ω,N^ω-DMTs and their oxides, as well as some bufotenin.^[1]

The species and nothospecies recognized in Lespedeza are:^[2]

The identity and/or specific validity of L. schindleri is unclear.^[3]

In addition, there are some species formerly in this genus but nowadays placed elsewhere (typically Lespedezinae, e.g. Campylotropis), such as:^[4]

• Lespedeza speciosa Schindl. = Campylotropis speciosa (Schindl.) Schindl.
• Lespedeza tomentosa Maxim. = Campylotropis pinetorum (Kurz) Schindl.
