TREES OF NORTH AMERICA 



arcuate and united within the margins and prominent reticulate veinlets; their petioles 

 stout, pubescent, rarely ^' long; stipules foliaceous, semilunar, acute or rounded at the 

 apex, glandular-dentate, coated below with hoary tomentum, often ^' long, caducous. 

 Flowers: aments cylindrical, densely flowered, erect on short tomentose branches, 

 the staminate l^'-2' long and ^' broad, the pistillate 2^ '-3' long, and ^' broad; their 

 scales yellow or tawny, the staminate oblong-obovate, rounded at the apex, covered 

 with long white hairs, much longer than the more acute pubescent scales of the pistil- 

 late anient; stamen 1, with an elongated glabrous filament, or very rarely 2, with 

 filaments united below the middle or nearly to the apex; ovary short-stalked, ovate, 

 conical, acute, and gradually narrowed into the elongated style, with entire or slightly 

 emarginate stigmas. Fruit ovate, narrowed above, light red-brown, about Y long. 



* A much-branched tree, occasionally 25-30 high, with a short contorted often 

 inclining trunk sometimes 1 in diameter, and slender branchlets coated at first with 

 hoary tomentum, pubescent and tomentose and dark red-brown or orange color during 

 their first winter, becoming darker, pubescent or glabrous, and sometimes covered 

 with a glaucous bloom in their second season; more often shrubby and 6-15 tall. 

 Winter-buds acute, nearly terete, light red-brown, pubescent or puberulous, about 

 Y long. Bark about ^' thick and broken into irregular closely appressed dark brown 

 scales tinged with red. Wood light, soft, close-grained, pale red, with thick nearly 

 white sapwood. 



Distribution. Banks of streams and low moist ground; Cook Inlet and Kadiak 

 Island, Alaska, southward in the neighborhood of the coast to Santa Barbara, Cali- 

 fornia.

Leaves revolute in the bud, elliptical-lanceolate to obovate, acute or occasionally 

 rounded at the apex, gradually narrowed below into short thick petioles, coated 

 above as they unfold with thin pale deciduous tomentum and covered below with a 

 thick mass of snowy white lustrous hairs persistent on the mature leaves, entire, 

 often somewhat wrinkled, dull yellow-green above, 2'-4', long, I'-l^' wide, with 

 broad yellow midribs; stipules linear-lanceolate to filiform, entire, ^'-f long, usually 



persistent until midsummer. Flowers: aments appearing in June when the leaves 

 are nearly fully grown, stout, erect, tomentose, stalked, on lateral pendulous branchlets.
