PICEA ENGELMANNI (Engelmanri). 



Oardeners' Chronicle, 1868, p. 1085. 

 Veitch's Man. Com/, ed. 2, p. 431 (1900), 



A TREE attaining in America a height of 100 to 150 feet and a girth 

 of 12 to 15 feet ; branchlets slender, light brown ; the young shoots 

 paler in colour and pubescent. Bark in young trees smooth and 

 silvery ; scaly in old trees. 



Buds conic, about an eighth of an inch long, with reddish-brown 

 scales. Leaves persisting four to five years, quadrangular in section, 

 with acute callous tips, - 1 inch long, pointing forwards, glaucous at 

 first but becoming darker later. Cones ovoid-cylindric, about 2 inches 

 long, and f - 1 inch in diameter, light green tinged with crimson 

 when fully grown, becoming afterwards shining brown ; scales thin with 

 toothed margins. 



This spruce occurs at altitudes varying from 3,000 to 11,500 

 feet in the Rocky Mountains from Alberta and British Columbia to 

 Arizona and New Mexico, and westward to the Cascade Mountains of 

 Washington and ^Oregon, often forming pure forests. It was dis- 

 covered on Pike's Peak in Colorado by Dr. C. C. Parry in 1862, and 

 introduced a few years later. It is rare in cultivation. 



Picea Engelmanni somewhat resembles P. pungens, the former 

 having less prickly leaves, which when bruised emit a disagreeable 

 odour. In its native habitats it sometimes fruits profusely when 

 young, the leader being bent down with the weight of the cones. 



The Bayfordbury specimen, planted in 1879, is 14 feet high. The 

 cones photographed were obtained from the Arnold Arboretum, U.S.A.
