The fruits consists of one or two drupes up to 2 cm (0.8 in) across. The plant has a generation span of 25 years. The habitat for Coscinium fenestratum spans South Asia and parts of Southeast Asia, from India to Indonesia. It can only thrive in a tropical climate and prefers mixed and dense evergreen forest, with fertile soil and high moisture. The plant has been determined to be native to Sri Lanka and the Western Ghats in India. It is unclear if the populations in Cambodia, Vietnam and west Malaysia are truly wild or the result of cultivation.
