Notes
Very variable, especially in the amount and density of tomentum, the more glabrous form (var. subnudus Ryan & Kerr) prevailing in the more humid areas including N.W. Malaya; in this respect resembling other dipterocarp species of the seasonal regions, e.g. Dipterocarpus turbinatus, Anisoptera costata, Shorea siamensis.
