Smithia is a genus of flowering plants in the legume family, Fabaceae. It includes 20 species of herbs or subshrubs native to sub-Saharan Africa, the Indian subcontinent, Indochina, southern China, Japan, Malesia, and northern Australia. The greatest diversity of species is in the Indian subcontinent, with 11 endemic species. Six more are widespread in southern and eastern Asia, and two of these, S. conferta and S. sensitiva, range further to northern Australia. Two species are endemic to sub-Saharan Africa. S. elliotii is native to Madagascar as well as mainland Africa, and S. conferta is also native to Madagascar. Typical habitats include seasonally-dry tropical grassland, wetlands, and streamsides.[1]
