(1147.) H. doronicoides, Lam. Ton-. & Gray Fl. II., 327, in part. 



In the valley of the Kaministiquia, west of Lake Superior, a species 

 of Helianthus, which produces large tubers, was observed in profusion 

 near Point Meuron in July, 1869. Not having seen perfect specimens 

 we are still uncertain what species it is but refer it here for the present.
