Trees, deciduous, to 15 m. Bark gray to light brown, scaly. Twigs deep red, 1-2 mm diam., glabrous. Terminal buds red-brown, ovoid to subconic, 2.5-5 mm, glabrous or scales somewhat ciliate. Leaves: petiole 6-23 mm, glabrous or with a few persistent hairs. Leaf blade broadly ovate to elliptic or obovate, 40-130 × 20-90 mm, base cuneate to obtuse, margins with 3-5(-7) oblong lobes and up to 10 awns, apex acute; surfaces abaxially glabrous except for conspicuous axillary tufts of tomentum, veins raised, adaxially planar, glabrous. Acorns biennial; cup thin, saucer-shaped, 4-6 mm high × 9-14 mm wide, covering 1/3 nut, outer surface puberulent, inner surface glabrous or with a few hairs around scar, scale tips appressed, acute; nut globose or ovoid, 9-14 × 9-14 mm, glabrous, scar diam. 4-7.5 mm.


Phenology: Flowering spring.
Habitat: Granitic outcrops and dry slopes and knolls
Elevation: 50-500 m
