63. TowNSENDiA STRiGOSA Nutt. Common on the road 

 to Moab and along McElmo Creek. 



64. TowNSKNDiA FENDI.ERI Gray. Usually found growing 

 on mesas through the whole region. 



65. Aster frondosus T. & G. Court House Wash. 



65a. Aster tortifolius Gray ? There are no glandular 

 hairs or viscidity about this plant as in A. tofiifolms and A. 

 Wrightii, but it dififers more essentially from A. venustus which it 

 resembles in shape of leaves and manner of growth, though not so 

 stout. It differs from A. venustus in the depressed hairs of the 

 akenes which are pappus-like at the top, the ray flowers are 

 violet with a hairy tube, akenes about half as long as in y^. ven- 

 ustus, truncate instead of obovate, style branches about one- 

 quarter as long. This with A. Wrightii, tortifolius, and venustus 

 form a well-marked group, and future material and investigation 

 may resolve them into one species.
