THE LAECH. 175 



No. 7. Laeix Ltallii, Pwrlatore, Mr. Lyall's Larch. 



Leaves on the branchlets in bundles of from 40 to 50, erectly 

 spreading, curved, narrow, linear, blunt-pointed, rather soft, 

 and three-quarters of an inch long, and about a quarter of a 

 line broad; those on the young shoots are single and much 

 longer. Branches nearly horizontal, with the young shoots 

 and buds densely clothed with a whitish cobweb-like wool. 

 Buds on the branchlets oval-globose, with the perula or scaly 

 covering very short, imbricated, and of a brownish colour, and 

 with the margins of the scales fringed with a long, cobweb- 

 like wool. (Full-sized cones unknown.) Young cones solitary, 

 somewhat reflexed, sessile, oblong, blunt-pointed, and two 

 inches long, and one inch broad. Scales numerous, loosely 

 imbricated, somewhat cartilaginous, nearly orbicular, rounded 

 or subemarginate at the ends, rather convex on the back, and 

 with a ciliated or fringed margin. Bracteas elliptic, crenated 

 on the edges, with the middle nerve prolonged into an awl- 

 shaped point longer than the scale. Seeds small, with the 

 wings the same length as the scales. 



A pyramidal tree, growing from 36 to 45 feet high, in north- 

 west America, on the eastern slope of the Rocky Mountains, 

 in the Galton Range, and Cascade Mountains, at an elevation 

 of from 6000 to 7000 feet. 



This is a very remarkable species, on account of the cobweb- 

 like wool that clothes the leaf-buds and young shoots, and the 

 long fringe of the scales that surround the buds.
