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 Part of the Fruiting Ament of Swamp Cottonwood, Popului keterophylla. , 420.
