 numerous : involucre glabrous nearly or quite to the base ; the inner bracts in the female 

 heads obtuse : akenes glandular : the spatulate and as it were petaloid tips of the male pap-

 solitary head : bristles of the male pappus gradually and moderately enlarged upward. —

 dilated tips ! — Rocky Mountains at lower elevations, extending to New Mexico, Oregon, 

 and Brit. Columbia; first coll. by Drummond. Passes into the typical form as to stature, and
