This list brings the total of species added to the flora of Western 

 Oregon since these studies were begun to 309. As the number 

 listed in the Flora of the Northwest Coast is 161 7, it will be 

 observed that the authors of that work failed to mention about 

 sixteen per cent, of the total number of species in their territory. 

 In other words, the student who depended wholly on their 

 manual would fail to determine about every seventh species which 

 he encountered — a margin of possible error much too large to be 

 comfortable. 



W^hether this state of uncertainty will be relieved by the next 

 manual due to appear in this district — Professor Abrams' 

 Illustrated Flora of the Pacific Coast, the first volume of which is 

 understood to go to press about the first of the year — still remains 

 on the lap of the gods. The Oregon botanists realize that a close 

 personal survey of their territory yet remains to be made; and 

 as the value of "absent treatment" as applied to the preparation 

 of a flora is somewhat open to question, it is within the bounds 

 of possibility that these local supplementary lists may still be 

 not wholly valueless after several more of these "comprehensive" 

 manuals have come and gone!
