Type : There seems to be no particular specimen designated as the type of this species 



by Dr. Gray. The sheet in the Gray herbarium, regarded as that upon which 



the original description was founded, contains portions of plants from three dif- 

 ferent localities, two from New York and one from Michigan, varying however 



but very little from each other. These were taken as the basis of the above 



description. 

 General distribution : New England to Minnesota.
