 This is a very doubtful species. 



Hieracium Scouleri Hook. H. griseum Rydberg. Rydberg in making his 

 untenable species goes directly in the face of the statement of Gray in the 

 Synoptical Flora page 427 that S'couler distributed specimens of H. cyno- 

 glossoides as H. Scouleri, and in the face of Hooker's original description.
