This species is veixclose to H.fendleri (A. Gray) Heller, to which it has been referred. 

 Tiie plant called H. macrophyllum Nutt. in Cooper's Report is probably //. albifrona, which 

 has also been confused with //. occidentale (S. Wats.) A. Gray, a species of nioi-e southern 

 range. 



Tire type specimen of H. congestum Wiegand really came from Mount Rainier (Mount 

 Tacoina) and not from Tacoma as published.

Two quite distinct forms of this species occur, but satisfactory characters to separate them 

 are not evident. The coast form like Piper's .5000 has dark blue flowers on long peduncles, 

 and thick leaves coarsely and doubly crenate-dentate, while the form away from the imme- 

 diate coast has thinner leaves, simply dentate, and pale flowers on shorter peduncles. 



Hydrophyllum tenuipes has heretofore been referred to //. virginicum L.
