An intricately branched shrub, with numerous contorted stems from three to ten feet tall ; or 

 occasionally rising with a single trunk five or six inches in diameter to the height of eighteen or twenty 

 feet and forming a small tree with a round-topped spreading head.^ The bark of the trunk is thin, 

 smooth, dark brown, and covered with small closely appressed scales. The branchlets are slender and 

 marked with small pale or dark raised lenticels ; when they first appear they are dark green, more or 



less tinged with red, and coated with hoary pubescence, and during theh first winter are red-brown 



or 



ashy gray and pubescent or puberulous, growing glabrous and darker in their second year and ultimately 

 dark brown or nearly black. The winter-buds are ovate, obtuse, about an eighth of an inch long, and 

 covered by dark chestnut-brown rather loosely imbricated glabrous or pilose scales. The leaves are 

 convolute in the bud, obovate or rarely oblong in outline, gradually or abruptly wedge-shaped at the 

 base, and from three to seven but mostly five-lobed, with acute bristle-tipped lobes and wide shallow 

 sinuses ; the terminal lobe is ovate, elongated, and rounded and three-toothed or acute and dentate or 

 entire at the apex ; the lateral lobes are spreading, mostly triangular and acute, or the upper pair, 

 which are generally much larger than the others, are broad, oblique, and repand-lobidate at the apex ; 

 or the leaves are broad at the apex and slightly three-lobed and entire below, or deeply three-lobed 

 above and sinuate below, or occasional leaves are oblong or oblong-obovate and entire with undulate 

 margins ; when they unfold they are dull red and puberulous or pubescent on the upper surface and 

 coated on the lower and on the petioles with thick pale tomentum ; when half gi'own they are light 

 yellow-green, lustrous, slightly pubescent above and tomentose below, with conspicuous tufts of silvery 

 white bail's in the axils of the veins ; and at maturity they are thick and firm, dark green and lustrous 

 above, and covered below with pale or silvery white pubescence, from two to five inches long and from
