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 orange..
