 few opposite branches and with the whole plant very pubescent, almost 

 tomentose. First leaves simple, lanceolate, the mature leaf unfolding two 

 pair of small, lateral leaflets. Flowers terminal, on the long, almost naked 

 branches. Leaves of the exterior involucrwn eight, ovate-lanceolate, slightly 

 acuminate, as long as the interior, nearly glabrous. Florets of the ray eight, 

 yellow, dilated at the summit, and from specimens appearing to be undu- 

 late. Seed nearly round, slightly winged, emarginate and crowned with a 

 short pappus more resembling a leaf than an awn. Chaff of the receptacle 

 linear, acute, longer than the florets of the disk. 



Grows in the western districts of Georgia.
