Dipterocarpus obtusifolius is a common species of tree in the family Dipterocarpaceae found throughout Southeast Asia, including Andaman Islands, Myanmar, Thailand, Cambodia, Laos and Vietnam.[2][3][4][5]
Three varieties have been identified: var. subnudus Ryan & Kerr; var. glabricalyx Smitinand; and var. vestitus (Wall. ex Dyer) Smitinand. While legitimate, these varieties are as yet of low confidence level.[4][6] The variety D. obtusifolius var. subnudus differed by having completely hairless leaves and is found only in the south of Cambodia, Vietnam and Thailand.[3]
Trees are large, up to 30m tall, grow in dry dipterocarp forest, and the red brown wood is used in general construction.[2] In Cambodia, the resin from the tree is used to make torches, drinking water was obtained by cutting young stalks and the wood gave boards regarded as non-durable in construction,[3] while in some areas of the Kompong Chhnang Province it is an important firewood source.[7]
