Leguminosae are the third dominant angiospermic family and second to Graminae for food. Besides, hosting a large number of endemic species, the Indian subcontinent is the centre of origin and diversity of a number of cultivated legume crops. A part from their value, there is a great concern for the severe erosion of biodiversity. The present work is expected to through new light on such issues and much awaited comprehensive taxonomic details. Crotalaria is an important economic genus and C. juncea L. (Sunhemp) is second to jute for fibre. World over there are 600 species of the genus. The present work is the outcome of years of herbarium studies and field observations. In introduction, general discussion on chromosomes, pollination, anatomy and morphology of seeds, uses etc. have been given. Available chromosome numbers shape and size of pollen and other details are given against the respective species. 100 illustrations and 115 photographs including 8 SEM photographs of seeds are given. Many critical studies have been done and taxonomic decision taken accordingly. The genus is divided into 6 sections and 12 subsections including 5 new subsections. Two new varieties and one new record for India are added in this work. 6 species and l variety reduced to synonymy; 4 species and l variety reinstated; l species reinstated and retained as variety; 2 species reduced and retained as varieties; 2 new formal, l new record for India and 2 name changes were made earlier status of C. huillensis Taub. explained.
