A tree, usually fifteen or twenty feet tall, with a trunk five or six inches in diameter and 



occasionally rising to the height of fifty feet 



rigid branches which form a narrow irregular head, but 



and forming a trunk eighteen or twenty inches in diameter and a broad round-topped shapely head 



The bark of the trunk is from three quarters of an inch 



inch and a haH in thickness, and 



divided into thick nearly square plates from one to two inches long and 



ed with small dark brown 



ly black scales sHghtly 



ged 



th red. The branchlets are stout, rigid, and roughened by 



numerous elevated lenticels, and are coated at first with dense fulvous hoary tomentum of articulate and 



stellate hairs ; their covering gradually disappears, and during their first winter they 

 sometimes tinged Avith red, and glabrous or puberulous, becoming darker in 



their second 



dark brown 

 sason. The 



buds are ovate, acute, covered by numerous rather loosely imbricated bright chestnut-brown 



ciliate on the margins, and often a quarter of an inch 



vigorous branches, or frequently 



obtuse and much smaller. The leaves are involute in the bud, oblong-lanceolate or oblong-obovate, 

 radually narrowed and wedge-shaped or sometimes rounded at the base, acute or rounded and 



undulate marerins, or on the extremities of 



g 



apiculate at the apex, and 



with shghtly thickened 



vigorous sterile branches occasionally three-lobed at the apex and variously lobed on the margins ; when 

 they unfold they are bright pink and pubescent on the upper surface, and coated on the lower with 

 thick silvery white tomentum, and when fuUy grown are firm in texture, blue-green, lustrous, and con- 

 spicuously reticulate-venulose above and coated below with pale tomentum, from two to five inches long 

 and from half an inch to an inch and a half wide, with stout yellow midribs raised and rounded on the 

 upper side and remote obscure primary veins forked and united within the margins ; they are bo 



on 



& 



oved and flattened petioles from one quarter to one half of an inch in length and fall irregularly 



ly in winter. The stipules are oblong-obovate or linear-lanceolate, from one
