A bushy tree, occasionally twenty-five feet in height, with a short trunk six or eight inches in 
diameter, and stout ascending branches which form a broad round head; or usually much smaller and 
often shrubby in habit. The bark of the trunk is thin, reddish or olive green, or gray tinged with red, 
and slightly divided by shallow fissures into appressed plate-like scales. The branchlets are slender and 
coated at first with hoary tomentum which gradually disappears; during their first winter they vary 
from reddish purple to dark orange-brown and are marked by scattered raised lenticels and roughened 
by the conspicuous elevated leaf-scars, and in their second year grow lighter and reddish brown. The 
buds are oblong, gradually narrowed and rounded at the apex, full and rounded on the back, with thin 
margins, flattened on the inner face by pressure against the stem, bright light chestnut-brown, and 
nearly a quarter of an inch long. The leaves are conduplicate in the bud, oblong-obovate, oblong- 
elliptical or lanceolate, gradually narrowed and wedge-shaped or rounded at the base, acuminate and 
short-pointed or acute at the apex, and remotely and irregularly serrate, usually only above the middle, 
with small incurved glandular teeth, or rarely entire ; when they unfold they are thin, pale gray-green, 
glabrous or villous and often tinged with red on the upper surface, and coated on the lower with pale 
tomentum or pubescence ; and at maturity they are thick and firm in texture, dull green and glabrous 
or puberulous on the upper surface, and on the lower pale blue or silvery white and coated with pale or 
rufous pubescence, especially along the midribs, veins, and conspicuous reticulate veinlets which are 
impressed on the upper side, from one to three inches long and from half an inch to an inch wide, with 
slender often reddish pubescent petioles from one quarter to one half of an inch in length. The stipules 
are foliaceous, semicordate, acute, glandular-dentate, sometimes nearly half an inch long on vigorous 
shoots, and deciduous. The aments appear with the unfolding leaves, and are erect and terminal on 
short leafy branches with small and often scale-like leaves; their scales are ovate or oblong, rounded at 
the apex, broader on the staminate than on the pistillate plant, yellow below, rose-color at the apex, 
coated with long pale silky hairs, and persistent under the fruit ; the aments of the staminate plant are 
cylindrical-obovate, narrowed at the base, from three quarters of an inch to an inch long and from one 
half to three quarters of an inch broad, densely flowered, silvery white before and pale yellow after the 
opening of the flowers ; the aments of the pistillate plant are oblong-cylindrical, loosely flowered, and 
about an inch in length. The stamens are two in number, with free glabrous filaments. The ovary is 
cylindrical, villous with long silky white hairs, long-stalked, gradually narrowed at the apex, and crowned
