 (1889). 



A tree, rarely one hundred feet high, usually much smaller, with a tall trunk occasionally three feet 

 in diameter and comparatively small spreading branches which make a narrow or often, when not 

 crowded by other trees, a broad round-topped head of upright rigid or of graceful pendulous branches. 

 The bark of the trunk is from one half to three quarters of an inch thick, slightly ridged by shallow 

 irregular interrupted fissures and covered with light or dark gray closely a2:)pressed scales- The branch- 

 lets are stout and terete, and when they first appear are slightly angled and clothed, Hke the pedicels, 

 the inner surface of the leaves and the flower-clusters, with thick pale tomentum, and during their first 

 year are rather bright red-brown, nearly glabrous, pubescent or tomentose, marked with conspicuous 

 pale lenticels, and in winter with pale emarginate leaf-scars which are sometimes almost equally lobed or 

 are elongated, with the lower lobe two or three times as long as the others, and which display minute and 

 mostly marginal clusters of pale fibro-vascular bundle-scars ; in their second year the branches become 

 light or dark gray. The terminal buds are broadly ovate, acute or obtuse, and from one half to three 

 quarters of an inch in length, being two or three times as large as the axillary buds, which, when they 

 appear on the young branchlets in early spring, are coated with long white hairs ; the three or four 

 outer bud-scales are ovate, acute, often keeled, or apiculate^ thick and firm, dark reddish brown and pilose 

 on the outer surface, and usually fall late in the autumn, disclosing the closely imbricated ovate rounded 

 and short-poinfed inner scales which are clothed externally with thick fight yellow silky lustrous tomen-
