A TREE attaining a height of 80 to 120 feet with a girth of 6 to 9 

 feet. Branchlets quite distinct in character, long, slender, whip-like, 

 pendulous, 6 to 8 feet long and about J inch in thickness. 



Leaves radially arranged, about an inch long, linear, convex on 

 both surfaces, obtuse or shortly pointed ; ventral surface dark green 

 and shining, with a prominent midrib ; dorsal surface with lines of 

 stomata. Bark grey, peeling off in small square scales and exposing 

 the brown cortex below. 



Cones oblong, narrowed at both ends, 2 - 5 inches long by f - 1 

 inch in diameter, green when young, orange-brown when mature ; 

 scales broadly obovate with entire rounded margins; bract minute, 

 concealed, oblong, denticulate in the upper margin. Seed with a

Picea Sreweriana, one of the rarest of American conifers, occurs 

 only on northern slopes in small groves at an altitude of about 4,000 

 to 6,000 feet on the main divide of the Siskiyou Mountains between 

 Oregon and California at the head waters of the Illinois River, also 

 in a smaller grove at the head waters of the Josephine Creek, 40 

 miles north-west of the grove previously mentioned, and in two or 

 three other localities. It was discovered by Thomas Howell in 1884. 

 The local name is the Weeping Spruce. 



A young specimen, two feet high, was planted at Bayfordbury 

 in 1908. This and the small tree at Kew, which is about three feet 

 feet high, are probably the only specimens in Great Britain. 



The cone illustrated was collected by Mr. F. R. S. Balfour in 

 1907.
