Notes
The typical form of this species grows in the submontane forest at 600-1500 m, and has small, narrowly ovate to linear-lanceolate leaves, small fruits and cupules with 5-6 lamellae. Specimens from the lowland forest, recognized by KING and others as L. (Quercus) wenzigiana, usually have larger leaves, cupules and fruits. In KEP 94394, SFN 10775, from Malay Peninsula, HONING s.n. from Sumatra, and SAN 26163, S. 5385, 18030, from Borneo, the leaves, cupules and fruits are intermediate. Specimens from 1500-1800 m, formerly recognized as L. symingtoniana, have much smaller leaves, cupules and fruits than those of L. rassa, but several intermediates also occur.
