OREGON COAST FLORA 347 



often two meters or more in height. In the more open places 

 small plants are abundant. Among the commonest are Aira caryo- 

 phyllea, agrostis alba, Campanula scouleri, Deschampsia elongata, 

 Disporum smithii, Fragaria chilccnsis, Holciis lanatus, Hypericum 

 anagalloidcs, Hypochxcris radicata, Jitncus cffusiis var. hcspcrius, 

 Maianthemimi dilatatum, and-Viola sannenfosa. 



In several places there are groups of small hillocks sparingly 

 wooded. Their contour indicates that they are old sand dunes that 

 have become fixed by the development of. a mantle of vegetation 

 over their surface. Here Pinits contorta is rather low and widely 

 branched but not distorted. Arctostaphylos tomcntosa and A. 

 uva-ursi are particularly plentiful, and there is an abundance of 

 herbaceous vegetation. 



Within the area under consideration there are several fresh 

 water ponds and swamps. Sand lake, about two miles below 

 Seal Rocks, with the marshy tract adjoining it, illustrates well 

 this formation. In the shallow water at the northern end of the 

 lake there is a colony of Nymphcca polysepala and one of Potamo- 

 geton natans. Along the margin of the water there is an abundance 

 of LilcEopsis occidcntalis and Sparganium augustifoliiim. A dense 

 border of Carex obnupta extends much of the way around the 

 ■ake. The swamp tract runs northward for some distance, term- 

 inating in a sphagnum bog of moderate size. Here were found 

 several species not elsewhere noted: Carex leptalea, C. sitchensis, 

 Comarmn palustre, Drosera rotundifolia, Eriophonim chamisonis, 

 and Trientalis arctica. 



To the eastward the low forest area under consideration rises 

 gradually into the great Coast mountain forest. The former is 

 wholly wanting about the bays, where some protection is afforded 

 from the westerly winds. Except where fires have swept over them 

 or extensive lumbering operations have been carried on, the western 

 slopes of the Coast mountains are covered with a magnificent 

 growth of Picea sitchensis, Pseudotsuga mucronata, and Tsuga 

 heterophylla, with other trees in much smaller numbers. With 

 this forest we are not particularly concerned and no detail account 

 of it will be given. 



In studying the coast flora from the taxonomic standpoint one is 

 impressed with the inconsistencies of the systematists in their 

 treatment of those forms, that have assumed special characteristics 

 as the result of maritime influences. Thus if the beach forms of 

 Achillea millefolium, Agrostis alba and Sagina occidentalis should 

 receive varietal or even specific recognition, there is no legitimate
