Rance: Western Texas to southern Arizona and southward. 
New Mexico: Grant County; mesa west of Organ Mountains. Mesas and dry 
hills, in the Lower Sonoran Zone. 
A very handsome plant, growing in dense flat-topped clumps 20 cm. high or less. 
The heads are very showy with their large white rays. It would be well adapted to 
use as a border plant in cultivation.

are even more showy than those of that species.
