A tree, sometimes forty to fifty feet in height, with a tall trunk twelve to eighteen inches in 
diameter, and small spreading branches which form a narrow oblong round-topped head. The bark 
of the trunk is from a quarter to half an inch in thickness, pale red-brown, and divided by shallow 
fissures into narrow longitudinal ridges, the surface of which is broken into small square persistent 
scales. The branchlets are slender and at first bright green and glabrous or slightly puberulous, but 
are dark red and marked with many minute pale lenticels in their first winter, and later become dark 
brown or red-brown. The winter-buds are a quarter of an inch long and covered with pale chestnut- 
brown ovate apiculate slightly pubescent scales, scarious on the margins and obscurely keeled on the 
back ; the scales of the inner ranks are lanceolate, acute, bright red above the middle, ciliate with silky 
hairs, and sometimes an inch long when fully grown, and leave when falling narrow ring-like scars 
which mark the base of the branchlets during two or three years. The leaves are ovate to ovate-oblong, 
acute or often taper-pointed at the apex, cordate or rounded at the base, and finely serrate with straight 
or incurved rigid subulate teeth ; when they unfold they are dark red-brown and pilose on both sur- 
faces with scattered deciduous white hairs, and at maturity they are thick and firm in texture, glabrous,
