Distribution. Borders of streams, swamps, and bottom-lands often covered with water; New Jersey (Morristown, Morris County and Pittsgrove, Salem County), near Wilmington, Delaware, southward through the coast and middle districts to Putnam (San Mateo) and Citrus Counties, Florida, through the Gulf states to the valley of the Trinity River, Texas, and through Arkansas and southeastern Missouri to central Tennessee and Kentucky, the valley of the lower Wabash River, Illinois, and southern Indiana eastward to Jefferson County (C. C. Deam); conspicuous from the silvery white bark, the massive trunk, and the broad crown of large bright-colored foliage.

Leaves obovate or oblong to lanceolate, acute or acuminate or rounded at apex, gradually or abruptly cuneate or rounded or subcordate at the narrow entire base, irregularly and coarsely crenulate-toothed with rounded, acute, or sometimes nearly triangular oblique teeth, when they unfold orange-green or bronze-red, very lustrous, and glabrous above with the exception of the slightly pilose midrib, green and coated below with soft pale pubescence, at maturity thick and firm or subcoriaceous, yellow-green and rather lustrous on the upper surface, paler and covered by fine pubescence on the lower surface, 4½′—9′ long, 1½′—3′ wide, with a stout yellow midrib and conspicuous primary veins, often much broader near the bottom of the tree than on fertile upper branches; turning dull orange color or rusty brown in the autumn; petioles stout or slender, ½′—1′ in length. Flowers: staminate in elongated hirsute aments; calyx light yellow, pilose and deeply divided into 7—9 acute segments tipped with clusters of pale hairs; pistillate in short spikes on stout puberulous dark green peduncles, their involucral scales covered with pale hairs; stigmas dark red. Fruit on short stout stems singly or in pairs; nut ovoid or ellipsoidal, rounded and rather obtuse or pointed at apex, bright chestnut-brown, very lustrous, 1′—1½′ long, ⅝′—1′ thick, inclosed for about half its length or sometimes only at the base in a turbinate or cup-shaped thin cup light brown and pubescent on the inner surface, reddish brown and hoary-pubescent on the outer surface roughened or tuberculate, especially toward the base, by small scales thickened and knob-like with nearly triangular free light brown tips.
A tree, usually 60°—70° or occasionally 100° high, with a trunk 3°—4° or rarely 6°—7° in diameter, divided generally 15° or 20° above the ground into large limbs spreading into a broad open rather irregular head, and stout branchlets green tinged with purple or bronze color and glabrous or pilose when they first appear, light orange color or reddish brown during their first winter, becoming dark gray or brown; on dry exposed mountain slopes often not more than 20°—30° tall, with a trunk 8′—12′ in diameter. Winter-buds ovoid, acute or acuminate, ¼′—½′ long, with bright chestnut-brown scales pilose toward the apex and ciliate on the margins. Bark of young stems and small branches thin, smooth, purplish brown, often lustrous, becoming on old trunks and large limbs ¾′—1½′ thick, dark reddish brown or nearly black, and divided into broad rounded ridges covered with small closely appressed scales. Wood heavy, hard, strong, rather tough, close-grained, durable in contact with the soil, largely used for fencing, railway-ties, and fuel. The bark, which is rich in tannin, is consumed in large quantities in tanning leather.
Distribution. Hillsides and the high rocky banks of streams in rich and deep or sometimes in sterile soil; coast of southern Maine, southern New Hampshire and eastern Massachusetts, southward to Delaware and the District of Columbia, and along the Appalachian Mountains and their foothills to northern Georgia (Wilkes County); ascending to altitudes of 4000°—4500°; in northern Alabama; westward to the shores of Lake Champlain, western New York; southeastern and southern Ohio, and southern Indiana westward to Orange County (C. C. Deam); and to central Kentucky and Tennessee, and northeastern Mississippi (Alcorn, Prentiss and Tishomingo Counties); rare and local in New England and Ontario; abundant on the banks of the lower Hudson River and on the Appalachian hills from southern New York to Alabama; most common and of its largest size on the lower slopes of the mountains of the Carolinas and Tennessee, here often forming a large part of the forest.
× Quercus Sargentii Rehd., believed to be a hybrid of Quercus montana and the European Q. Robur L., has been growing for nearly a hundred years at what is now Holm Lea, Brookline, Norfolk County, Massachusetts.
