the few rays light-yellow. S. Amer. B.M. 1536. A 

 striking plant for winter decoration, the star-like fls. 

 (or heads) being produced in great abundance ; now 

 becoming disseminated in this country.

 low, conspicuous. Western U. S. in the mountains and 

 to Alaska. Var. exaltatus, Gray, has been offered: 1-3
