WESTERN HEMLOCK 



Tsuga heterophylla (Rafinesque) Sargent 



Western hemlock is a tall tree with graceful feathery branches, 

 quite different from the mountain hemlock in habit and in fruitage. 

 It sometimes grows two hundred feet high, with a trunk six to nine 

 feet in diameter. The small brown cones, not more than an inch long, 

 are produced abundantly, and contrast with the background of shiny, 

 dark green leaves. The leaves are marked on the lower surface with 

 white bands. 



This species of hemlock occurs from western Montana to north- 

 ern California, Alberta, and Alaska. 



The specimen was obtained at Glacier House, near Glacier, British 

 Columbia, at an elevation of 3,500 feet.
