3YNGENESIA FRU5TRANEA. 417 



Root perennial. Stem about two feet high, slender, simple, soraetimeg 

 divided at the base, glabrous. Leaves all opposite, abruptly rounded at 

 base, triphnerved, paler underneath. Flowers fewy small, terminal. Pe- 

 duncles or small branches generally opposite. Leaves of the involucrum 

 about as long as the disk, somewhat hispid on the inner surface. Florets of 

 the ray ten to twelve, narrow, scarcely an inch long; of the disk not numer- 

 ous, yellowish. Pappus subulate. Chaff of the receptacle undivided, pu- 

 bescent, and fringed along the summit. 



Sent to me under this name by Dr. Schweinitz from Salem, North-Caro- 

 lina. Found abundantly in the western districts of Georgia. The latter 

 rather more hispid and rough than my specimens from North-Carolina: in 

 all other respects exactly similar. 



Flowers August — October.
