A tree, occasionally eighty to one hundred feet in height, with a trunk rarely exceeding two feet 

 in diameter, and slender upright branches which form a narrow head ; or usually much smaller. The 

 bark of the trunk is from one half to two thirds of an inch thick and separates freely into long loose plate- 

 like light brown scales tinged with red. The branchlets are slender, dark reddish brown or ashy gray, 

 lustrous and marked with numerous pale lenticels ; when they first appear they are slightly glandular 

 and coated with loose caducous pale tomentum -, they become glabrous or puberulous during the summer, 

 are marked during the winter with small nearly oval or obscurely three-lobed slightly elevated leaf-scars, 

 and in their second year grow dark brown, ultimately turning gray. The buds are slightly flattened, 

 acute, dark reddish brown, and clothed with caducous yellow glands. The terminal bud, which varies 

 from an eighth to a quarter of an inch in length and is often covered, especially while young, with 

 pale scattered hairs, is about twice as large as the axillary buds, which are often solitary and frequently 

 nearly sessile. The leaves are composed of from seven to thirteen leaflets, which increase slightly in 

 size from the lowest to the uppermost, and slender dark red puberulous or tomentose terete petioles, 

 and vary from nine to fifteen inches in length ; the leaflets are ovate-lanceolate, long-pointed, falcate, 

 equilateral, and gradually rounded or wedge-shaped at the base, or oblique and very unequally wedge- 

 shaped, or with one side rounded and the other wedge-shaped at the base j they are serrate with minute 

 remote teeth or conspicuously and coarsely serrate, and sessile or petiolulate, the terminal leaflet, which 

 is sometimes obovate and rarely rounded at the apex, being more or less decurrent by its regular wedge- 

 shaped base on a slender stalk often nearly an inch long, or rarely nearly sessile ; when they unfold 

 they are coated, like the petioles, with pale tomentum and covered with yellow persistent glandular dots, 

 and at maturity are from three to five inches in length, from half an inch to an inch and a half in 

 width, thin and membranaceous, dark green on the upper surface, and on the under surface brown 

 and rather lustrous and more or less pubescent or tomentose, especially along the slender midribs, which 

 are also tomentose on the upper side, and along the slender primary veins connected by finely reticulate 



The catkins of staminate flowers, which appear when the leaves are about a third grown, are 



vein 



lets. 



or sometimes from leaf-bearing buds on branches 



solitary or fascicled and are produced from separate 



of the previous year and at the base of branches of the year ; they are hirsute and from two and one 



half to three inches long, with common peduncles one third of an inch in length and ovate-lanceolate
