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. The variety ''D. obtusifolius'' var. ''subnudus'' differed by having completely hairless leaves and is found only in the south of Cambodia, Vietnam and Thailand. Trees are large, up to 30m tall, grow in dry dipterocarp forest, and the red brown wood is used in general construction. 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, while in some areas of the Kompong Chhnang Province it is an important firewood source.
