Hab. Port Discovery, Nisqually, Puget Sound, &c. — This species 

 extends on the western side of the continent from Sitcha south to 

 California (where the Russian collectors long ago gathered it, and 

 recently Dr. T. M. Bigelow), and eastward to the New England 

 States, Labrador, and Newfoundland. N.frigida has a more northern 

 range, and doubtless includes both N. corymbosa and N. sagittata. As 

 to the genus, Fries has rightly enough reduced it to Petasites, of which 

 it forms merely a radiate section.
