354 Rydberg: Notes on Rosaceae 



this genus in but one species, even if he admits several varieties, 

 is unsatisfactory. He even makes the very distinct P. anseri- 

 noides a variety of Potentilla Anserina. My treatment is not satis- 

 factory to Professor Fernald and to several other North American 

 botanists, being too radical; but Professor Fernald, who has tried 

 a kind of compromise, will not be followed by all. There is no 

 doubt but that he knows the New England species better than 

 anyone else, but the name Potentilla pacifica Howell does not 

 belong to the eastern plant, and Argentina subarctica is not a 

 synonym of it. If he had treated them as varieties I would have 

 been satisfied, for what he and many others call varieties, I call 

 species. 



Argentina Anserina (L.) Rydb. and A. argentea are represented 

 by numerous specimens in our herbaria. The others are less 

 well represented. In the herbaria of the New York Botanical 

 Garden and Columbia University are found the following. The 

 lists I had from the U. S. Nat. Herbarium and the Gray Herbar- 

 ium I have mislaid and can not find.
