LIMBER PINE 



Pinus fl exilis James 



Limber pine appears to enjoy growing in difficult positions and is 

 often seen springing from clefts in the rocks on the mountain sides, 

 where it would seem impossible for a tree to obtain a foothold. The 

 branches are exceedingly flexible, bending readily under the heavy 

 weight of the developing cones, and seeming scarcely able to with- 

 stand the strain. 



Limber pine is found in the Rocky Mountain region from northern 

 Mexico to Alberta, and in some of the higher desert ranges westward 

 to southern California. 



The specimen sketched was obtained from Devils Gap, east of Lake 

 Minnewonka, twenty-five miles from Banff, Alberta, Canada, at an 

 altitude of 4,000 feet.
