Camus in having completely entire leaf margin, solitary cupule, long stalks of fruits, deeply cup-shaped or turbinate cupules, with a number of horizontal filiform lines. The species differs in its nut enclosure ca. 1/2 - 2/3 of the nut, adaxially glabrous leaf blades, secondary veins 11-12 pairs and faintly to very faintly visible hairs on the outside of the cupule. A table showing the morphological comparison ofLithocarpus dahuoaiensiswithLithocarpus macphailiiandLithocarpus encleisocarpusis also provided.
