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. ( Agoseris 
hirsuta Greene’), the type of which is said to have been collected by Douglas and by Scou- 
ler on ‘Menzies Island and sandy banks of the Columbia,” and which is referred by A. 
Gray¢ to Trorimon humile. 
We have seen no specimens of Troximon humile A. Gray (Macrorhynchus humilis Benth.) 
from Washington, and doubt its occurrence.
