Prosartes lanuginosa major Hook, has been associated with P. oreganum Wats., but mis- 

 takenly, since the latter species does not range east of Idaho. A Richardson specimen in 

 the Gray Herbarium perhaps of the type collection is unquestionably P. trachycarpum 

 Wats. We have, therefore, no hesitancy in giving the .synonymy as above.
