 pterodonta. Leaves 2-2J by |-1 in., tips rounded. Corymbs scaberulous ; heads J in. 

 diam. Achenes (young) glabrous. — The wing may be an inconstant character. The 

 specimens are poor, and it may prove a form of P. tomentosa.

A tall shrub. Leaves 1-2 in., variable in breadth, rigid, nerves raised on both
