scarious margins. 



A tree^ occasionally seventy or eighty feet in height^ with a trunk two or three or rarely four feet 

 in diameter, but usually much smaller, and slender branches spreading gradually into a comparatively 

 narrow open or conical round-topped head. The bark of the trunk is from one half to three quarters 

 of an inch in thickness, light reddish brown slightly tinged with red, and generally smooth but broken 

 on old trees by shallow narrow fissures into irregular plates covered with small closely appressed scales. 

 The branchlets are slender, roughened with dark lenticels, glabrous and reddish brown, and in their 

 second year grow dark brown tinged with red or grayish brown. The winter-buds are ovate, 

 acute, about an eighth of an inch long, and covered by dark chestnut-brown scales, with pale 



The leaves are involute in the bud, ovate-lanceolate or rarely lanceolate-obovate, 

 often somewhat falcate, gradually narrowed and acute at the base, acute and apiculate at the apex, 

 and entire with slightly undulate margins ; when they unfold they are light yellow-green and lustrous 

 on the upper surface, and coated on the lower with pale caducous pubescence, and at maturity are 

 glabrous, light green and rather lustrous above, dull and paler, or rarely coated with hoary pubescence 

 below,^ conspicuously reticulate-venulose, from two and a half to five inches in length and from a quarter 

 of an inch to an inch in width, with slender yellow midribs raised and rounded on the upper side and 

 obscure primary veins forked and united about half way between the midribs and the margins ; they are 

 borne on stout grooved petioles from one eighth to one quarter of an inch in length and turn pale 

 yellow in the autumn before falling. The flowers open when the leaves are about a quarter grown, the 

 staminate borne in haiiy slender-stemmed aments from two to three inches in length and the pistillate 

 on slender glabrous peduncles. The calyx of the staminate flower is yellow and hairy, and is divided 

 into four or five ovate acute se^nents ; the stamens are four or five in number, with oblong glabrous
