* Abies grandis Lindley. Lowland White Fir. 



Range. — Coast region from Vancouver Island to California (Sonoma County), 

 and from Washington and Oregon to northern Idaho and Montana. 



Note on nomenclature. — Abies aromatica Rafinesque (1832), an older name 

 than Abies grandis Lindley (1833), possibly should be taken up for this species. 

 In the author's opinion, however, this name is doubtfully applicable. 



1J In the Pacific Northwest it is common to speak of the species of Abies as " Balsam Firs," to distinguish 

 them from Douglas Fir (Pseudotsuga). While the expression "True Firs" is sometimes used, the term 

 "Balsam Firs" seems preferable.
