reason why the same treatment should not be given the equally 

 well marked maritime phases of Aster douglasii, Fcstnca rubra, 

 RiDiicx mcxicanus, and others. 



Many species of plants that play a more or less important part 

 in the total make-up of the vegetation of our territory have re- 

 ceived no special mention in the foregoing discussion. It seems 

 desirable therefore, to add the following distributional list, in 

 which are included the names of all the seed plants ascertained 

 to occur within our limits. Doubtless the list is far from complete 

 for this section, especially as regards the flora about the bays. 



For the records of a number of the species as well as for assist- 

 ance on some points of nomenclature, I am indebted to Principal 

 J. C. Nelson, of the Salem High School, who collected about New- 

 port and Toledo in the summer of 1916. 



Taxaceae. 

 Taxus brevifolia Nutt. — Found sparingly about the bays. 



Pinaceae. 



Thuja plicata Donn.- — Only a few small trees were noted. 



Pinus contorta Dougl. — Abundant everywhere, the distribution 

 almost exactly coinciding with the area here under consideration. 



Pseudotsuga mucronata (Raf.) Sudw.^ — Moderately plentiful, but 

 always small. 



Picea sitchensis Carr. — The most abundant tree excepting Pinus 

 contorta, with which it is usually mingled. In protected situations 

 the great forest of Spruce and Douglas Fir comes down to the 

 edge of salt water, as is the case about the bays ; elsewhere the 

 trees are much smaller. 



Tsuga heterophylla (Raf.) Sarg. — Moderately plentiful in the 

 zone of low forest. 



Sparganiaceae. 



Sparganium angustifolium Michx. — Plentiful in Sand lake, two 

 miles south of Seal Rocks. 



Najadaceae. 



Potamogeton natans F. — Plentiful in Sand lake. 



P. pusillus F. — In pools near Newport. 



Zostera marina F. — Abundant at the mouth of Yaquina bay and 

 in drift along the beach. Good flowering and fruiting specimens 

 were secured, which apparently is unusual.
