. North American trees : being descriptions and illustrations of the trees growing independently of cultivation in North America, north of Mexico and the West Indies . Trees. Rough-Leaved Cornel 743 The branches are slender, stiff and ascending, forming a narrow head. The bark is thin, close, greenish or grayish brown, the twigs slender, round, reddish brown to purplish. The leaves are opposite, firm, eUiptic, oval to ovate, 4 to 12 cm. long, taper-pointed at the apex, narrowed or tapering at the base, slightly wavy or quite entire on the margin, green and shghtly appressed-hairy above, paler and somewhat hairy beneath; the leaf-stalk is 5 to 15 mm. long. The flowers, appearing in April or May, are in loose, flat compound cymes 3 to 6 cm. across, on nearly smooth pedicels; the calyx-tube is urn-shaped and woolly; the corolla is 5 to 6 mm. across, the petals linear-oblong or linear-lanceolate, pointed and white. The fruits are subglobose drupes about 6 mm. in diameter, of a pale blue color, supported on stout pinkish stalks; the stone is somewhat oblique, 3 to 4 mm. broad, slightly less in length, faintly ribbed and scarcely furrowed.
