FOEM A large tree, which may attain a height of 90 ft. with a diameter of 3-4 feet. The form of the forest grown tree is distinct from the open grown. Open grown specimens have a pyramidal crown with limbs originating all along the trunli from near the base to the narrow top. Lateral branches are wide-spreading and rather horizontal near the base, ascending and short at the top. Forest grown specimens have straight, slightly tapering, rather smooth trunks which are free from branches often for 50 ft. from the ground. BARKâGrayish-brown to brown, witli long furrows separating long, rather loose, scaly ridges. See Fig. 85. T-V^riGS Usually slender, round, usually smooth but sometimes slightly hairy, shiny, bitter, covered with a few orange-colored inconspicuous lenticels, and contain white pith which may show a tendency to become chambered. BUDSâAlternate, circular in cross-section, densely covered with thick, pale, silky hairs, terminal buds about 2/5-4/6 of an inch long and oblong; lateral buds i-J of an inch long, blunt- pointed, nearly surrounded by leaf-scars. Buds are covered with valvate scales, the outer ones falling in spring, the inner ones developing into stipules. LEAVESâAlternate, simple, ovate to oblong, thin, 4-12 inches long, pointed at apex, tapering or rounded at base, entire on margin, green and slightly downy beneath, with prominent midrib and primary veins on lower surface. Fall in response to first heavy frost in autumn. LEA
