Leaves ovate-lanceolate, or narrow lanceolate (f. _angustifolia_ Anders.), acuminate and long-pointed at apex, cuneate or rounded at base, finely serrate, 3′—5′ long, 1′—1½′ wide, covered when they unfold with scattered pale caducous hairs, at maturity coriaceous, smooth and lustrous, dark green above, paler below, with a broad yellow midrib, and slender primary veins arcuate and united near the margins; petioles stout, yellow, puberulous, glandular at the apex, with several dark or yellow conspicuous glands, ¼′—½′ long; stipules nearly semicircular, glandular-serrate, membranaceous, ⅛′—¼′ wide, often persistent during the summer. Flowers: aments erect, tomentose, on stout puberulous peduncles terminal on short leafy branchlets, the staminate oblong-cylindric, densely flowered, about 1½′ in length, the pistillate slender, elongated, 1½′—2′ long, often persistent until late in the season; scales oblong or obovate, rounded, entire, erose or dentate at apex, light yellow, nearly glabrous or coated on the outer surface with pale hairs, often ciliate on the margins; stamens usually 5, with elongated free filaments slightly hairy at base; ovary narrowly cylindric, long-stalked, elongated, glabrous, with nearly sessile emarginate stigmas. Fruit: cylindric, lustrous, about ⅓′ long. A tree, occasionally 25° high, with a short trunk 6′—8′ in diameter, erect branches forming a broad round-topped symmetrical head, and stout glabrous branchlets dark orange color and lustrous in their first season, becoming darker and more or less tinged with red the following year; usually smaller and shrubby in habit. Winter-buds narrowly ovoid, acute, light orange-brown, lustrous, about ¼′ long. Bark thin, smooth, dark brown slightly tinged with red. Distribution. Banks of streams and swamps; Newfoundland to the shores of Hudson’s Bay and northwestward to the valley of the Mackenzie River and the eastern base of the Rocky Mountains, southward to southern Pennsylvania, northeastern Iowa, the Turtle Mountains, North Dakota, and eastern Nebraska; very abundant at the north, rare southward; a variety from extreme northeastern New England and adjacent New Brunswick and Quebec (var. _intonsa_ Fernald) is distinguished by its often linear leaves rufous pubescent during the season on the under side of the veins and by its pubescent branchlets; a shrub or tree up to 25°. 10.
