Leaves obovate, narrowed and cuneate or broad and truncate at base, divided by wide deep sinuses rounded in the bottom into 5—7 lobes, the terminal lobe ovate, acute, 3-toothed toward the apex, or entire, the lateral lobes spreading or oblique, sometimes falcate, especially those of the lowest pair, gradually tapering and acute at the dentate apex, or obovate and broad at apex, when they unfold light bronze-green stained with red on the margins, lustrous and puberulous above, coated below and on the petioles with pale scurfy pubescence, at maturity thin and firm, dark green and very lustrous above, pale below, with large tufts of pale hairs in the axils of the conspicuous primary veins; 4′—6′ long, 2′—4′ wide, with a stout midrib; late in the autumn gradually turning deep scarlet; petioles slender, yellow, ½′—2′ in length. Flowers: staminate in hairy aments 2′—3′ long; calyx puberulous and divided into 4 or 5 oblong rounded segments more or less laciniately cut on the margins, shorter than the stamens; pistillate on short tomentose peduncles, their involucral scales broadly ovate, tomentose, shorter than the acuminate calyx-lobes; stigmas bright red. Fruit sessile or short-stalked, solitary or clustered; nut nearly hemispheric, about ½′ in diameter, light brown, often striate, inclosed only at the base in a thin saucer-shaped cup dark red-brown and lustrous within, and covered by closely appressed ovate light red-brown thin puberulous scales. A tree, usually 70°—80° high, with a trunk 2°—3° in diameter, often clothed with small tough drooping branches, or when crowded in the forest sometimes 120° high, with a trunk 60°—70° tall and 4°—5° in diameter, slender branches beset with short-ridged spur-like laterals a few inches in length, forming on young trees a broad pyramidal head, becoming on older trees open and irregular, with rigid and more pendulous branches often furnished at first with small drooping branchlets, and slender tough branchlets dark red and covered by short pale silvery tomentum, soon becoming green and glabrous, lustrous dark red-brown or orange color in their first winter, growing darker in their second year and ultimately dark gray-brown. Winter-buds ovoid, gradually narrowed and acute at apex, about ⅛′ long, with imbricated light chestnut-brown scales puberulous toward the thin sometimes ciliate margins. Bark of young trunks and branches smooth, lustrous, light brown frequently tinged with red, becoming on older trunks ¾′—1¼′ thick, light gray-brown, generally smooth and covered by small closely appressed scales. Wood heavy, hard, strong, coarse-grained, light brown, with thin rather darker colored sapwood; sometimes used in construction, and for shingles and clapboards.
