Abstract: -The reproductive biology is adjacent to the floral and phenology and floral biology, of Butea monosperma (Lam.) Taub. Phenology is the study of reproductive biology and intricated by seasonal variations in climate as well as habitat. A good-looking tree B. monosperma is commonly called as bastard teak or palash or flame-of-the-forest. Butea monosperma is a class of Butea, inhabitant to hot and sub-tropical chunks of the southeast Asia, and Indian subcontinent, ranging across India, Pakistan, Bangladesh, Sri Lanka, Nepal, Thailand, Vietnam, Myanmar, Laos, Cambodia, Malaysia, and western Indonesia. This tree is protected in dry, dry thorm forest and paddy field area located in this region of Central India that is in east Vidarbha. Phenological studies shows that even though the species shows a regular flowering season but changing periodic events. Photoperiod / day length and temperature as climatic effective factor considered for three years in this study. Periodic events in biological life cycles of Butea monosperma is summarized for flowering season of three years, which are 2020, 2021 and 2022. It is found that flowering detected in the first / second week of March, 2021only within seasons of three year of study.
