A. Potentilleae. Of 



the species there described it is probably nearest to Niittallii Lehm. * 

 from which its simple stems, subtomentose leaves and the strik- 

 ingly congested inflorescence distinguish it. It is noticeably large- 

 leaved and the stems are stoutish, the leaves becoming smaller and

tlic stems virgate upward.

* Jn my opinion, it is very closely related to/*. Blaschkcaua. I included it in 

 that species in my Monoj^rnpli, Ijut am now inclined to believe it to be distinct. It 

 differs from that species in less deeply cut leaves and much less dense tomcntum. — P.
