A tree, ^iglity to one hundred feet in height, with a tall straight trunk often two feet in diameter 

 and stout sUghtly spreading branches which form a comparatively narrow rather open head. The bark 

 of the trunk is from one half to three quarters of an inch thick, dark brown tinged with red, and 

 broken irregularly into small thin appressed scales. The branchlets are slender and are coated at first 

 with lustrous golden or brown peltate scales which often do not entirely disappear until the second year ; 

 during their first winter they are light brown or ashy gray and marked with small scattered pale 

 lenticels and small oval emarginate elevated leaf-scars, and in their second year they become dark 

 reddish brown. The terminal buds are from an eighth to a quarter of an inch long, broadly ovate and 

 rather obtuse, the outer scales being coated with thick brown scurfy pubescence and soon splitting so 

 that the inner scales, which are covered with thick pale tomentum, are displayed ; the axillary buds are 

 much smaller and are acute, shghtly flattened, sessile or short-stalked, and often solitary. The leaves 



composed of from five to eleven leaflets and of slender 



or slightly grooved scurfy-pubescent 



petioles, and are from seven to fourteen inches in length ; the leaflets are ovate-lanceolate or the upper 



which are usually twice as larg 



those at the base of the leaf, are broadly obovate ; they 



acute with short or elongated points at the apex, usually equally or sometimes unequally wedge-shaped 

 or rounded at the narrow base, coarsely serrate with remote incurved teeth, and short-petiolulate or 

 nearly sessile, the terminal leaflet being decurrent on a broad stalk rarely half an inch long ; when they 

 unfold they are coated with scurfy brown pubescence on the lower surface and are covered on the 

 upper by circular more or less persistent clusters of brown scales ; at maturity they are thin and firm, 

 dark green above, and below are more or less pubescent or nearly glabrous and silvery white and very 

 lustrous, changing late in the season to bright bronzy brown ; they are four or five inches in length and 

 from an inch to an inch and a half in breadth, with pale midribs scurfy-pubescent on both sides and 

 numerous straight primary forked veins and thin cross-veinlets. The catkins of the staminate flowers, 

 which are three or four inches long and are coated, Hke the bract and calyx of the flower, with dark 

 brown scurfy pubescence, have a common peduncle three quarters of an inch long and linear-lanceolate 



bracts half an inch in length ; the bract of the flower 



oblong 



and about twice 



to 



the broadly ovate rounded lobes of the calyx ; there are six stamens with oblong emarginate
