Stenis 1-3 feet high, very leafy. Leaves an inch or less in length, half a line 



wide, those of the branches almost setaceous. Heads barely two lines in diameter; 



the rays linear-oblong. Achenia turbinate, 10-ribbed, very strongly silky-villous. 



Pappus of more numerous, longer, narrower and acute palese than in the allied G. 



sphicrocephala (P/. Fendl), sometimes all distinct, often irregularly concreted more 



or less, similar in the ray and disk. G. sphserocephala has the receptacle equally 

 conical.*
