Habit.—A small or medium-sized tree, 20-45 feet high, with a trunk diameter of 8 inches to 2 feet; attaining farther south a maximum of 100 feet in height, with a trunk diameter of 4-6 feet; variable; most commonly the rough, straight trunk, sometimes buttressed at the base, branches a few feet from the ground, sending out a few large limbs and numerous slender, horizontal or slightly drooping and more or less tortuous branches; head wide-spreading, flattish or often rounded, with deep green foliage which lasts into late autumn with little change in color, and with cherry-like fruit which holds on till the next spring.

Bark.—Bark of trunk in young trees grayish, rough, unbroken, in old trees with deep, short ridges; main branches corrugated; secondary branches close and even; branchlets pubescent; season's shoots reddish-brown, often downy, more or less shining.

Winter Buds and Leaves.—Buds small, ovate, acute, scales chestnut brown. Leaves simple, alternate, extremely variable in size, outline, and texture, usually 2-4 inches long, two-thirds as wide, thin, deep green, and scarcely rough above, more or less pubescent beneath, with numerous and prominent veins, outline ovate to ovate-lanceolate, sharply serrate above the lower third; apex usually narrowly and sharply acuminate; base acutish, inequilateral, 3-nerved, entire; leafstalk slender; stipules lanceolate, soon falling.

Inflorescence.—May. Appearing with the leaves from the axils of the season's shoots, sterile and fertile flowers usually separate on the same tree; flowers slender-stemmed, the sterile in clusters at the base of the shoot, the fertile in the axils above, usually solitary; calyx greenish, segments oblong; stamens 4-6, in the fertile flowers about the length of the 4 lobes, in the sterile exserted; ovary with two long, recurved stigmas.

Fruit.—Drupes, on long slender stems, globular, about the size of the fruit of the wild red cherry, purplish-red when ripe, thin-meated, edible, lasting through the winter.

Horticultural Value.—Hardy throughout New England; grows in all well-drained soils, but prefers a deep, rich, moist loam. Young trees grow rather slowly and are more or less distorted, and trees of the same age often vary considerably in size and habit; hence it is not a desirable street tree, but it appears well in ornamental grounds. A disease which seriously disfigures the tree is extending to New England, and the leaves are sometimes attacked by insects. Occasionally offered by nurserymen and easily transplanted.
