Reproductive biology of Butea monosperma (Fabaceae).

ABSTRACT: The reproductive biology encompassing phenology, floral biology, pollination and breeding systems, of Butea monosperma, a beautiful tree of the Indian subcontinent, was investigated in a protected dry, deciduous forest located in New Delhi.
