ZONAL DISTRIBUTION: Arid Transition and Canadian. 
This species is very close to H. fendleri (A. Gray) Heller, to which it has been referred. 
The plant called H. macrophyllum Nutt. in Cooper’s Report is probably H. albifrons, which 
has also been confused with H. occidentale (S. Wats.) A. Gray, a species of more southern 
range. 
The type specimen of H. congestum Wiegand really came from Mount Rainier (Mount 
Tacoma) 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 H. virginicum L.
