 flowering steins pubescent and above glandular, bearing solitary or 3 to 5 middle-sized heads : 

 involucre somewhat campauulate, 4 or 5 lines high, merely puberulent-glaudular, hardly at

 rough-hispidulous ; cauliue rarely 2 inches long ; of the branches half to less than quarter 

 inch long; uppermost passing into bracts of the (half-inch high) many-ranked obscurely 

 granulose-viscid involucre ; the green tips oblong-linear or shorter, or the inner linear : rays 

 three-fourths inch long, deep violet, large and numerous, rather broad : akeues little com-
