Papilionanthe teres was observed to exhibit intraspecific colour variations in its natural populations of West Bengal. Variations were observed in floral parts such as sepals, petals, and lip. The normal floral colour was light pink or purplish and flower lip was purplish red with yellow base and lined with purplish brown colour. The plant that showed variations was observed with flowers having white lip with yellow spur and all other floral parts were comparatively larger in size.
