A tree, often a hundred feet in height^ with a trunk sometimes free of branches for a distance of 

 forty or fifty feet above the ground and from three to seven feet in diameter, and stout branches 

 ascending at narrow angles and forming a round-topped rather compact head. The bark of the trunk 

 is from half an inch to an inch in thickness, and separates into thin closely appressed silvery white or 



ashy 



gray 



scales more or less deeply tinged with red. The branchlets are stout and marked with 



scattered oblong pale lenticels, and when they first appear are dark green and covered with pale caducous 

 hairs ; during their first winter they are bright red-brown or light orange-brown, and ultimately become 

 ashy gray. The buds are broadly ovate or oval, acute, a quarter of an inch long, and covered with 

 numerous thin closely and regularly imbricated dark red puberulous scales with pale scarious margins, 

 those of the inner ranks being coated on the outer surface with loose pale tomentum. The leaves are 

 convolute in the bud, broadly obovate or oblong-obovate, wedge-shaped or rounded at the broad or 



narrow entire base, acute, or acuminate with short broad points at the apex, and 



ly crenately 



lobed with oblique rounded entire lobes sometimes furnished with glandular tijDS ; or rarely they are 



entire^ with undulate margins ; when they unfold they are bright yellow-green, lustrous and pubescent 

 with scattered pale hairs above and coated below with thick silvery white or pale f errugineous tomentum, 

 and at maturity they are thick and firm, or sometimes membranaceous, especially on young and vigorous 

 branches, dark green and lustrous on the upper surface, which is glabrous or occasionally roughened with 

 scattered stellate hairs, more or less densely pubescent on the pale green or silvery white lower surface, 



from six to eigrht inches lonsr and from three to five inches wide, with 



midribs impr 



upper side, and slender primary 



obhquely to the points of the lob 



[ on the 

 ected by 



conspicuous reticulate cross veinlets ; they are borne on stout pubescent flattened and

half 



an 



inch 



iich and a half in length, and late in the

 with thick pale hairs, and caducous. The flowers appear from the end of March to the middle of May,
