A tree, rarely sixty feet in height, with a short trunk sometimes three or four feet in diameter, and 
stout elongated brittle branches which form a broad head, and dichotomous branchlets. The bark of 
the trunk varies from a quarter to a third of an inch in thickness, and is light brown tinged with red 
on the surface, which separates in large thin irregular scales. The branchlets, when they first appear, 
are green shaded with purple, and slightly puberulous; during their first winter they are thickened at 
the nodes, lustrous, light orange-color or gray-brown, covered with a slight glaucous bloom, and marked 
with large pale scattered lenticels, the outer layer of the thin bark separating easily from the bright 
green inner layer. The leaf-scars, in which appear a circle of conspicuous fibro-vascular bundle-scars, 
are large, oval, and elevated, and do not entirely disappear until the third or fourth year, when the 
The branch con- 
tinues to grow through the summer, the end dying in the autumn without forming a terminal bud, and 
appearing during the winter as a black scar by the side of the upper axillary bud. The axillary buds 
are minute, globose, and deeply immersed in the bark, with several pairs of chestnut-brown broadly ovate 
branches are reddish brown, and marked with a network of thin flat brown ridges. 
rounded slightly puberulous and loosely imbricated scales ; those of the inner ranks are accrescent, and 
when fully grown are bright green, pubescent, and sometimes two inches in length. The leaves are 
opposite or in threes, broadly ovate, rather abruptly contracted into slender points or sometimes rounded 
at the apex, cordate at the base, and entire or often laterally lobed ; when they unfold they are coated 
on the lower surface with pale tomentum, and are pilose on the upper surface ; and at maturity they are 
thin and firm, light green and glabrous above, pale and pubescent below, five or six inches long and 
1 Sometimes when not interfered with the branches grow to a great length, and, resting on the ground, form roots, and produce 
new trunks in succession (Garden and Forest, iii. 536, f. 68).
