THE PINE SUB-FAMILY. 



177 



color of the young branchlets is pale fawn, and of the older 

 ones, reddish. 



We do not think this species has been introduced into 

 this country, but from the representations of the discover- 

 er, we should be pleased to hear of its success with us. 

 Gordon places it in the Tsugas, on account of the rather 

 flattish leaves ; but we prefer to follow the example of 

 Murray, and include it in the list of true Spruces, from 

 the fact of its leaves being spirally arranged all around the 

 branches and not in two rows.
