Mr. Sheldon regards the northern plant as distinct from the Californian, which may 

 prove to be the case. It is possible, also, that this is Leontodon hirsutum Hook.a {Agoseris 

 hirsutaGreeneb), the type of which is said to have been collected by Douglas and byScou- 

 Icr on "Meuzies Island and sandy banks of the Columbia," and which is referred by A. 

 Grayc to Troximon humile. 



We have seen no specimens of Troximon humile A. Ciray (J/«(7w7((/7it7(«.s7(u/AH7(i- Benth.) 

 from Washington, and doubt its occurrence.
