A dwarfish, bush-like plant attaining a height of ten or twelve feet, vigorous, dense-topped, hardy; trunk and branches stocky; branches smooth, grayish-brown; branchlets many, of medium thickness and length, thickly overspread with short pubescence, with short internodes, roughish, with a few large, raised lenticels near the base. Leaves numerous, two and one-eighth inches long, one and one-half inches wide, folded upward or flattened, broad-oval to obovate, velvety; upper surface dull, dark green, rugose; lower surface thickly pubescent, with a prominent midrib and veins; apex abruptly pointed; margin serrate; petiole three-sixteenths inch in length, reddish, pubescent, of medium thickness, with from twelve to fourteen small, globose, yellow glands, usually at the base of the blade. Buds very small, short, pointed, free, arranged as lateral buds and in clusters on small, short spurs; leaf-scars not prominent; season of bloom early; flowers appear with the leaves, white, thirteen-sixteenths inch across; borne singly or in pairs; pedicels short, thick, glabrous; calyx-tube reddish, campanulate, glabrous; calyx-lobes narrow, acute, serrate, slightly pubescent, erect; petals white, roundish-ovate, entire, with short claws; anthers tinged with red; pistil pubescent at the base, longer than the stamens, often defective. Fruit matures in mid-season; a half-inch in diameter, roundish, slightly compressed; cavity deep, narrow, abrupt; suture shallow; apex depressed, with adherent stigma; color currant-red; dots numerous, small, grayish, obscure; stem thickish, one-eighth to one-quarter of an inch in length, pubescent; skin thick, tender, adheres slightly to the pulp, covered with light pubescence; flesh light red, with light red juice, stringy, melting, sprightly, sour; good in quality; stone clinging, one-quarter of an inch long, one-eighth inch wide, oval, slightly pointed, with smooth surfaces. The habitat of _Prunus tomentosa_ is probably Central Asia though it is now to be found growing spontaneously in East Tibet and the Chinese provinces of Setschuan, Hupe, Kansu and perhaps Tochlii.
