blades or segments laciniate-toothed or cleft, tapering into a long 

 more or less spinosely toothed petiole; inflorescence beginning 

 near the base, diffusely branching; the heads on very short ped- 

 uncles, nearly globose, about 6 mm. long; bracts very narrow, 

 rigid, 12-18 mm. long, with a few spinose bristles at the base, not 

 at all scarious-margined ; bractlets about the size of the bracts, 

 short, scarious-margined below, broadening upward to a short 

 lobe on each side, the margined base inclosing the fruit and fall-
