As Dr. H. M. Hall has pointed out (Zoe, vol. 5, p. 266) both 

 pubescent and glabrous achenes occur in this species, though the 

 typical form as described by Nuttall has the achenes uniformly 

 pubescent, so far as known. My own number from Pyramid Peak 

 shows both pubescent and glabrous achenes in the same collection.
