glandular-scabrous: achenes compressed, cuneate-oblong, 
striate, strigose-pubescent. 
Very common in dry ground at altitudes of 7,000 to 9,000 
feet in the mountains and small parks of middle Colorado 
east of the main range. A most beautiful species, and none 
of the descriptions by Nuttall, or Gray, touch this; though 
it constitutes a very considerable part of the Colorado “Aster 
canescens” of the catalogues and herbaria.
