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 

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

 ler on "Menzies 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. Gray {Macrorhynchus humilis Benth.) 

 from Washington, and doubt its occurrence.
