 Stems forming a clump from a root apparently peren-

 lobed with spreading lobes, spinous-ciliate with longest 

 and stoutest spines at the ends of the largest divisions,

 current from the base of one leaf almost to the next; 

 heads either solitary at the ends of the branches or two 

 or three cymosely clustered ; involucres 2 to 2]/ 2 cm. long,
