TABLE 8. Plant* of the Arctic-Alpine Zone in Oregon- 1 



1 Taken in part from Piper (1906) and in part from lists of plants collected or identified in the field by the 

 writer and checked by Morton E. Peck. At best the list is fragmentary, but the species are so grouped as 

 to show the relationship of the Blue Mountain and Steens Mountain flora to that of both the Cascades on 

 the west and the Rocky Mountains on the east.
