Brief description: Subgenus Lepidobalanus, white oaks. An evergreen monoecious tree with a cross-checked bark. Leaves are firm, narrowly elliptic to oblong, simple, alternate, entire, pinnately veined, glabrous above, pubescent beneath with very tiny stellate hairs; the margins are entire. Flowers are unisexual, the staminate in slender catkins, the pistillate solitary or in small spikes. Fruits are a nut (acorn), partly enclosed by the persistent involucre -- the acorn cup. The acorn cup is turbinate-shaped, with acute scales. The acorns mature and sprout at the end of the first season.
