LIMBER PINE 
Pinus flexilis 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 ate exceedingly flexible, bending readily under the heavy 
weight of the developing cones, and seeming scarcely able to with- 
stand the strain. 
Limbet pine is found in the Rocky Mountain tegion from northern 
Mexico to Alberta, and in some of the higher desert ranges westwatd 
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.
