 bearded at the apex with a crest of short hairs, subcucullate : anthers 

 acutely appendaged at the apex, with longer cihate-fimbriate or 

 occasionally lacerated appendages at the base ; style somewhat dilated 

 below its division into branches and then hispidulous, with the 

 branches very long rather flat inside and puberulous-hispidulous 

 round the outside ; achenes obcuncate, narrowed at the base, truncate 

 at the apex, with several ribs, densely hispid all round (or very nearly 

 glabrous) ; pappus in several rows ; the sette rigid, hisijidulous, per-
