THE PLANTS OF THE PRIBILOF ISLANDS. 571 



115. Oxyria reniformis, Hook. 



Common in damp ravines or on damp s^ots on hillsides on both islands. 



116. Rumex acetosella, L. 



On sandy soil on St. Paul Island. 



117. Salix arctica, Pall. 



The common willow on both islands. 



118. Salix arctica, Pall., var. obcordata, Anders. 

 Rarer than the last. 



119. Salix phylicoides, And. 



Collected on Bogoslov Hill by Dr. Merriam. 



120. Salix reticulata, L. 



Common on hillsides and uplands on both islands. 



121. Salix diplodictya, Trautv. 



Not rare on St. Paul Island. Determined by Mr. P. A. Eydberg. 



122. Salix ovalifolia, Trautv. 

 Rare on St. Paul Island. 



123. Salix rotundata, Eydberg MS. 



A little willow, very abundant on a hillside near the village on St. Paul, has been 

 collected there every year since 1891. Mr. M. S. Bebb determined specimens collected 

 in 1891 and 1892, and wrote that he believed them to be" intermediate between 8. 

 rotundifolia and 8. ovalifolia. Mr. Theo. Holm, who examined specimens collected in 

 1897, considered them to be Salix return, L., forma, rotundifolia, Trautv., while Mr. 

 P. A. Eydberg believes them to be new. Lundstrom, to whom specimens were sent, 

 has at this writing not yet reported on them. This is, I believe, the same plant of 

 which Mr. Bebb wrote Dr. Merriam '' intermediate between S. arctica and 8. ovali- 

 folia — may possibly be a hybrid." I can not think it a hybrid. Distributed from 

 the herbarium of the Geological Survey of Canada as No. 16645.

 in one locality only (Tolstoi) on St. Paul Island.

Yery abundant on parts of St. Paul Island, but flowering early and soon hidden 

 by grass. 



128. Juncus balticus, Deth., var. haenkii (Mey.), Fr. Buch.
