This species has been considered to be the same as C. preslii Steiid., ba.sed on the C. lepo- 

 rina L. of Presl in Reliquiae Ilaenkeanae. • 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 bo the same. It is much more likely that C preslii is a form of C. /estiva. C. petasata 

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

 phaeocephala.
