121. Salix diplodictya, Trautv. 



ZJTot rare on St. Paul Island. Determined by Mr. P. A. Rydberg. 



122. Salix ovalifolia,-TrautY. 

 Bare on St. Paul Island. 



123. Salix rotundata, Rydberg 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 S. ovalifolia. Mr. Theo. Holm, who examined specimens collected in 

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

 P. A. Bydberg 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.
