It is very doubtful if this western plant is really separable from 

 the common Rosewort of Europe and northeastern North America ; 

 certainly the character indicated by the specific epithet "integri- 

 folium" will not serve to distinguish our Cordilleran form, since the 

 leaves on the same plant vary from entire or repand-dentate to sharply 

 toothed; nor is the assumed difference in color of the flowers to be 

 relied upon.
