My friend Dn Schweinitz sent me under this name a plant of which the 

 following is a brief description. The short and defective account of this 

 species in VVilldenow and Pursh, does not enable me to ascertain whether 

 we have all described the same plant. 



Root perennial. Ste/a tall, slender, sparingly branched, glabrous. Leaves 

 lanceolate, sometimes ovate-lanceolate, acuminate, conspicuously serrate, 

 thin, slightly scabrous on both surfaces, paler and sprinkled with hairs un- 

 derneath, on short petioles, the lower opposite, the upper alternate. Flow* 

 ers small, few, terminal. Leaves of the involucrum linear-lanceolate, about 

 as long as the disk, ciliate, with the hairs nearly obliterated towards the 

 summit. Florets of the ray eight to ten, yellow, about an inch longj of the 

 disk not numerous. Pappus nearly setaceous. Chaff of the mvolucrum 

 nearly as long as the florets, pubescent near the summit, with two lateral 

 teeth not opposite. 



Collected near Salem, North-Carolina, and to be found most probably 

 along the base of the Alleghany mountains in Carolina and Georgia.

Var. a. Pallidus. 



From Louisville, Georgia, I have received a specimen which at present 1 

 can mily arrange as a variety of the preceding. Stem very slender. Leaves 

 all opposite, narrow, lanceolate, long, taper " • - ^' 



acumbiate, very thin, nerves prominent, slightly scabrous, light green 



pubescent 



but 



j,„.„. ^ „.. Flowers few, small, terminal. Leaves oi 



the involucrum fewer than in the preceding variety, shorter than the disk 





fringed. Florets of the ray eight? small; of the disk not numerous 

 mens longer than the florets of the disk. Pappus setaceous. Chaff" of the 

 receptacle pubescent, entire or three-toothed at the summit. The chaff, the 

 involucrum, and the opposite narrow leaves seeai to mark this as a disunct 

 species. Sent by Mr. Jackson.

H. caule laevigato; 

 foliis oppositis, ovato- 



lanceolatis, acuminatls.
