Distribution. Nova Scotia, southern Quebec and Ontario to Manitoba and Saskatchewan (Saskatoon), and southward through New England, eastern and northern New York, the southern peninsula of Michigan and northern Indiana; in Pennsylvania (Lackawanna, Bucks, Northampton and Blair Counties); common in the New England coast region; a form (var. pubera Sarg.) with young leaves covered above with soft pale hairs and pubescent on the under side of the midrib and veins and villose petioles, flowers with a pubescent calyx-tube, in villose corymbs, becoming pilose when the fruit ripens, and young branchlets covered with long matted pale hairs, ranges from Newfoundland to the shores of Lake St. John, Province of Quebec, northern Ontario, Winnipeg and Manitoba, and southward through the maritime provinces of Canada, New England to southern Connecticut, northern and western New York (near Buffalo, Essex County), the northern peninsula of Michigan, northeastern Wisconsin; in central Minnesota (St. Cloud, Stearns County); common northward.

Leaves elliptic to ovate, acute, gradually narrowed or broad-cuneate at the entire base, coarsely doubly serrate above with spreading or incurved teeth tipped with deciduous dark red glands, and usually divided above the middle into 2 or 3 pairs of short acute or acuminate lobes, more than half grown when the flowers open during the first week of June, and then membranaceous and coated with soft pale hairs most abundant on the under side of the midrib and principal veins, and at maturity thick and coriaceous, dark green and lustrous on the upper surface, pale and puberulous on the lower surface, 3′—4′ long and 2′—3′ wide, with a stout midrib, 4—6 pairs of primary veins and conspicuous secondary veinlets; petioles stout, more or less winged toward the apex, villose, ultimately glabrous, tinged with red below the middle, 1½′—2′ in length, after midsummer often twisted at base, bringing the lower surface of the leaf to the light; leaves at the end of vigorous shoots usually more coarsely serrate and much more deeply lobed, with broadly winged petioles, and falcate coarsely glandular-serrate stipules sometimes 1′ in length. Flowers 1′ in diameter, on long slender pedicels, in broad loose lax many-flowered tomentose corymbs; calyx-tube narrowly obconic, tomentose, the lobes abruptly narrowed from a broad base, long, acute, entire, villose; stamens 10; anthers large, rose color; styles 2, or generally 3, surrounded at base by a narrow ring of pale tomentum. Fruit ripening usually early in October, on slender elongated pedicels, in broad many-fruited drooping glabrous or puberulous clusters, short-oblong to oblong-obovoid, rounded at the ends, bright carmine-red, marked by occasional large dots, ¾′—1′ long, and ¾′ in diameter; calyx conspicuous, with enlarged and elongated closely appressed lobes; flesh thick, yellow, sweet and mealy; nutlets 3 or rarely 2, thick, narrowed and acute at base, full and broad at apex, rounded and ridged on the back with a high broad ridge, about 7/16′ long.
A tree, sometimes 20° high, with a tall trunk often a foot in diameter, covered with dark brown scaly bark, ascending or spreading branches forming a broad open irregular head, and stout branchlets tomentose early in the season, becoming orange-brown, glabrous and very lustrous during their first summer, and light gray the following year, and armed with stout straight or curved chestnut-brown shining spines 2′—3′ long and usually pointed toward the base of the branch.
Distribution. Rocky shores of sounds and bays; coast of Maine, Islesboro and Belfast Bay to the island of Mount Desert (Waldo and Hancock Counties); in hedges, near Fredericton, York County, New Brunswick; Rivière du Loup, Kamouraska County, Province of Quebec (Brother Victorin).

Leaves broad-rhombic, oblong-obovate or rarely ovate, acute or rounded at apex, gradually narrowed and usually entire below, coarsely often doubly crenately-serrate above with usually glandless teeth, and divided above the middle or frequently only at apex into short broad rounded or acute lobes when the flowers open in May, thin and roughened above by short pale hairs and glabrous below, and at maturity firm and rather leathery in texture, or subcoriaceous, glabrous, smooth, dark green and somewhat lustrous on the upper surface, pale on the lower surface, 1′—1¼′ long, and 1′ wide, with a yellow midrib, and 3—5 pairs of primary veins extending obliquely to the point of the lobes; petioles slender, often slightly winged toward the apex, glandular at first with minute dark red caducous glands, ½′—1′ in length; leaves at the end of vigorous shoots broad-ovate or semiorbicular, usually more deeply and more generally lobed, often 3′ long and 2′—3′ wide. Flowers about ¾′ in diameter, on long slender pedicels, in 3—12-flowered thin-branched slightly villose corymbs; calyx-tube narrowly obconic, slightly villose toward the base, or glabrous, the lobes gradually narrowed from below, acuminate or short-pointed at apex, finely and irregularly glandular-serrate, glabrous or villose on the inner surface; stamens usually 20; anthers small, light yellow; styles 2 or 3, surrounded at the base by a narrow ring of pale tomentum, and villose below the middle with occasional long spreading hairs. Fruit ripening and falling at the end of September, in few-fruited drooping clusters, short-oblong, rounded at the ends, or subglobose and flattened at the ends, dull dark red or rusty orange-red or rarely yellow, marked by occasional dark dots, and about ½′ long; calyx only slightly enlarged, the lobes spreading or erect and frequently deciduous before the fruit ripens; flesh thin, yellow, dry and mealy; nutlets 2 or 3, broad and rounded at base, acute at apex, conspicuously grooved and ridged on the back with a broad rounded ridge, about ¼′ long.
A tree, occasionally 25° high, with a straight trunk 4′—6′ in diameter, covered with thin dark gray-brown bark, small rather erect branches forming a narrow open head, and slender branchlets, orange-green, glabrous or sometimes pubescent when they first appear, becoming bright chestnut-brown and lustrous, and ashy gray or gray tinged with red during their second year, and armed with thin straight or slightly curved bright chestnut-brown spines ¾′—1½′ long.
