 base. — St.-3^[r feet high^ erect, branched. L. slightly broader 

 just above the base then gradually narrowing to an acute point. 

 Heads twice as large as in the two preceding. Inv. usually -5-

 Marginal fr. with scalelike tubercles throughout but particu- 

 larly on the ribs. — \T. major is probably only a yellow-flowered
