The present paper deals with the morphometric and reproductive phenophases of two important tropical tree species, namely, Bauhinia variegata and Bauhinia purpurea. The study was carried out on nine trees selected from PunjabAgricultural University, Ludhiana and Dr. YS Parmar UHF Nauni, Solan. Phenophases like leaf bud swell, leafing, opening of bud, and flowering characteristics were recorded in year 2018-19. Phenophases were species-specific and dependent on the research area's environmental and meteorological circumstances. The present investigations revealed that mean days of leafing, bud opening, and leaf bud swell remains were similar in both species, but leaf area (cm2) was higher in B. purpurea than in B. variegata. The mean days of flowering were different in both species. Petal length and breath, filament length, were all higher in B. purpurea species, and the maximum anther dehiscence was observed between 7.30 and 8.30 am in selected genotypes. These discoveries are important for botany, especially in the fields of forestry and ecology, where they will help with work to improve genetics.
