Abstract

Crotalaria tetragona Roxb. ex Andr. (Fabaceae) considered to be close wild relative of cultivated C. juncea L. (sunnhemp) occurs in the tropical Asian region. Systematic study based on floral morphology and developmental aspects of tetragona was attempted. The study pointed out gross structural similarity of floral parts of this species with that of C. juncea but differences were apparent in development of floral parts.
