My friend Dr. 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 Willdenow and Pursh, does not enable me to ascertain whether 
we have all described the same plant. 
Root perennial. Stem 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 long; of the 
disk not numerous. Pappus nearly setaceous. Chaff of the involucrum 
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 I 
can only arrange as a variety of the preceding. Stem, very slender. Leaves 
all opposite, narrow, lanceolate, long, tapering to the summit but scarcely 
acuminate, very thin, nerves prominent, slightly scabrous, light green, but 
paler and pubescent underneath. Flowers few, small, terminal. Leaves of 
the involucrum fewer than in the preceding variety, shorter than the disk, 
fringed. Florets of the ray eight? small: of the disk not numerous. Sta- 
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 seem to mark this as a distinct 
species. Sent by Mr. Jackson.
