Note. 



I confess that I am unable to limit G. rotund/folia and C. Scheuchzeri, 

 as they are descriljed in Dj-. Gi-ay's Synopsis of the Gamopetalse. We 

 have evidently two forms which are both referred to C. rotundifolia. 

 My impression is that the true C. rotundifolia grows chiefly on river 

 banks, while the other which I may call the boreal form is found on 

 exjiosed shores, prairies and mountain tops. The form with linear or 

 narrowly lanceolate entire cauline leaves I refer to C. rotundifolia, 

 while the other with the stem-leaves more or less toothed much broader 

 and the lower leaves never linear, I include, in G. Scheuchzeri.
