[1] Dipterocarpus alatus ranges from West Bengal and Bangladesh through Myanmar, Thailand, Laos, Cambodia, Vietnam and the Philippines.

[1] It grows in evergreen and semi-evergreen lowland dipterocarp forests in valleys and foothills.

In Cambodia, the wood is much valued in construction and cabinetwork, when not exploited for its oily resin.

Generally, resin is collected for the following uses: wood lacquering, draught-proofing of boats and traditional medicine.

The bark of young trees is also used in traditional medicine, taken against rheumatism and diseases of the liver, and to stimulate appetite in cattle.
