. 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. As a shrub this plant takes the place at the South of the well-known northern Panicled cornel, Cornus candidissima Marshall, to which it is very similar, except in the different color of its fruit and twigs. 3.

The twigs are slender, hght green and hairy at first, soon becoming red-brown. The termi- nal winter buds are about 3 mm. long, sharp-pointed, the lateral ones smaller. The leaves are opposite, firm, elhptic to ovate or ov
