It resembles the T. occidcntah's L. of the East, but its cones are 

 larger, the fertile ones with 6 or more fertile flowers. It is rare in 

 Montana, belonging to the region west of the Rockies and growing 

 in cold, wet woods.

branched crown, shorter leaves and berries that require two years to 



mature. It grows on hillsides and in canons up to an altitude of 



2000 m.
