Tall tree with close, deeply furrowed bark; twigs soon glabrescent; lvs smooth at maturity except for conspicuous tufts of stellate hairs in the vein-axils beneath, deeply (5)7-lobed, the sinuses commonly elliptic and extending three-fourths the distance to the midvein, the lobes oblong or usually widened distally, each with several conspicuous teeth or small lobes above; acorn-cup flatly saucer-shaped, 1–2.5 cm wide, with closely imbricate, minutely puberulent scales, covering a third or a fourth of the 1.5–3 cm nut. Chiefly in moist, lowland soil; Pa. and Va. to Ind., s. Mich., Mo., and Kans., s. to Fla. and Tex.
A medium to large sized tree. It grows up to 40 m high. The leaves are 12-20 cm long. There are 7-11 toothed lobes. The notches between the lobes are deep. The base is rounded. The leaves are shiny green above and paler underneath. They finally become rich red in autumn. The leaf stalks are 5-7 cm long. The acorns are large. They are 15-30 mm long. The cup is shallow and saucer shaped. It is 15-30 mm across. It is grey and slightly hairy. The cup encloses about one third of the acorn.
