Distributed in: Bangladesh, Burma, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Sri Lanka, Thailand, Vietnam (Oceania and S.E. Asia)
Distribution overview: Widely distributed in the moist tropical forests of South and Southeast Asia where it is a dominant canopy tree. In peninsular Malaysia, it occasionally occurs as a coloniser of bare lands. In the area of natural distribution it is found in the lowlands and up to 800 m altitude, in areas with 1400-4000 mm rainfall/year. Prefers annual rainfall of more than 2000 mm a year, although it tolerates as little as 850 mm but then growth is slow. It thrives in areaswith uni- as well as bimodal rainfall regimes. Best growth when mean annual temperature is 20- 25C and absolute minimum of 5-10C. Outside its natural distribution it is grown in plantations in West and South Africa plus some Caribbean countries and Costa Rica..
