 Type Peck 16034, in a meadow along the John Day River 15 mi. 

 above Dayville, Grant County, June 17, 1927. 



One should hesitate to add another name to this already 

 over-named section of Potentilla, but the present form is so well 

 marked by its pubescence and leaf-characters as to demand 

 specific recognition. It was found plentiful in the type locality.
