heads. Involucrum many leaved, containing many flowers; leaves subu- 
late, pubescent, acute. Corolla longer than the involucrum, pale purple, 
externally villous. Seeds angular, villous along the angles. Pappus com- 
posed of five ovate, mucronate, lacerate scales, in which the midrib though 
transparent, is distinctly visible. Receptacle paleaceous, paleae linear. 
Var. a. Cyananthera. Stem simple, angular, furrowed, very pubescent
