LODGE POLE PINE 



Pinus contorta var. Murrayana. Pine Family 



A small, slender tree, with very thin bark. Leaves: delicately ser- 

 rulate. Fruit: cones oblong-cylindrical, slightly oblique at the base, 

 tapering towards the apex. 



The Lodge Pole Pine, often called Black or Jack Pine,

 recognized by its light orange-brown bark. The branches 

 are spreading below, growing upwards near the top, and

 the base, red. Fruit: cones oblong, promptly deciduous.

 beautiful trees, which grow in clusters out of woody cups,
