Four varieties have been described – D. o. var. cuspidatus, D. o. var. subnudus, D. o. var. glabricalyx, and D. o. var. vestitus – but all are now considered to be synonyms.^[2] The variety D. o. var. subnudus differed by having completely hairless leaves and is found only in the south of Cambodia, Vietnam and Thailand.^[4]

Trees are large, up to 30m tall, grow in dry dipterocarp forest, and the red brown wood is used in general construction.^[3] 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,^[4] while in some areas of the Kompong Chhnang Province it is an important firewood source.^[5]
