540 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Calais macrochaeta Gray is founded upon immature specimens collected by Spalding on 
the Clearwater, Idaho. They are undoubtedly young plants of C. linearifolia, as the pap- 
pus of that species shows just the transitions from young flowers to adult akenes needed 
to connect the differences supposed to be specific.

ZONAL DISTRIBUTION: Arid Transition. 
The distinctions relied upon by Professor Greene to separate two supposed species seem 
too unstable. In the type specimen of trorimoides the paleae are not “very unequal.”
