A deciduous cherry up to 30 ft high; young shoots glabrous. Leaves oval, obovate, or inclined to oblong, abruptly narrowed at the apex to a short slender point, rounded or slightly heart-shaped at the base, sharply and often doubly toothed, 3 to 7 in. long, 11⁄4 to 3 in. wide, glabrous above, distinctly downy beneath, especially on the midrib and veins; stalk 1⁄4 to 5⁄8 in. long, usually downy and furnished with one to three large glands. Flowers 1 in. wide, pink or white, produced before the leaves, three to six in a cluster, each on a hairy stalk 1⁄2 to 11⁄4 in. long. Calyx-tube bell-shaped, hairy, its reflexed awl-shaped lobes longer than the tube; petals narrowly oval, deeply notched at the end. Fruits globose, 1⁄3 in. wide, red. The flowers spring from the axis of an involucre of conspicuously glandular-fringed bracts. Bot. Mag., n.s., t. 174.
