Professor and Mrs. Hall in their Yosemite Flora cite Gray as the 

 author of the combination " Haplopappus disc&ideus" but they now 

 inform me that this was an inadvertence, the combination not having 

 been previously made.

While in general the material from the northern Rockies has the 

 leaves somewhat broader than much of our California representation, 

 and in so far justifies Dr. Rydberg's statement that his M. grindeli- 

 folium has the foliage spatulate, yet such plants are by no means rare 

 among our western collections (compare Hooker and Gray from Castle 

 Peak) . This breadth of leaf reaches a maximum in Heller 7182, which 

 has been made the type of a new species, M. imbricata, which, in my 

 opinion, is not distinguishable by characters of even varietal sig- 

 nificance.
