Leaves 4' to 7 Leaf ;- Slightly resinous, ovate, acute, cov- ered with bright red brown scales, one- fourth an inch long and half the size of the flower-buds. Leaves.—Alter- nate, four to seven inches long, two, to three inches broad, broadly ovate, cor- date or truncate or rounded with a small sinus at base, finely or coarsely crenate- ly-serrate with in- curved glandular teeth, acute, or short pointed or rounded at apex; midrib and veins conspicuous, and sometimes downy. They come out of the bud involute, covered with thick white toraen- tum, when full grown are dark green above pale and smooth be- neath. In autumn they turn dull yellow or brown. Petioles terete, slender, tomentose or smooth, two and one- half inches long; stipules caducous. Flowers.—March, April. Staminate am- ents are broad, densely flowered, erect at first but finally pendulous, two to two and one-half inches long with stout, brittle, hairy stems. Their scales are narrowly oblong- ovate, brown, divided into many narrow light red brown lobes and falling as the am- ents lengthen. Stamens, twelve to twenty, with slender filaments and large dark red anthers, are inserted on an oblique, slightly concave disk, with spreading border. Pis- tillate aments few-flowered, one to two inches long; ovary ovoid, terete or three- angled ; style short, stout with two or three dilated, two or three-lobed stigmas. Fruit.—In maturing the fruiting aments become four to six inches long, pedicels half an inch long; capsules ripen in May, are ovate, acute, red brown, two to three- valved, one-half an inch long; seed small, dark brown, surrounded by many short, silvery white hairs which are often tinged with Please note that these images are extracted from scanned page images that may have been digitally enhanced for readabilit
