This species has been considered to be the same as C. preslii Steud., based on the C. lepo- 

 rina L. of Presl in Reliquiae Haenkeanae. The type of C. preslii came from the shores of 

 Nootka Sound, and there is scarcely a possibility that the high alpine C. leporina americana 

 can be the same. It is much more likely that C. preslii is a form of C.festiva. C. petasata 

 Dewey, the type of whivh is in the Gray Herbarium, is a very different species from C . 

 phaeocephala.
