Root perennial. 



times a little roughened, often smoolh. 



Stem four to five feet high, sparingly branched, some- 

 Leaves ovate-lanceolate, slightly 



acuminate, triplinerved, scabrous on both surfaces, tapering at base to a 

 petiole and varving much in the length of the petiole and the coarseness ol 



reus 



the serratures. Floicers large, terminal. Leaves of the involucrum nume- 



linear-lanceolate, fringed, imbricate, at least in four or five series, 

 squarrose. Florets of the ray about twelve, purple, two inches long, nar- 

 row, two-cleft at the summit, reflected; of the disk numerous, small. Seea 

 four-angled, inversely pyramidal, the summit concave and crenulated. He- 

 ceptacfe convex, chafty, the chaff narrow, acuminate, nerved, glabrous, 

 longer than the seeds and florets, and with their acute, rigid points forming 

 a hispid capitulum. _ 



This species appears at present to exhibit many varieties. It differs so 

 much in its generic characters, in involucrum, seed, and chafi" of the recep- 

 tacle, from most if not all of the other species of the genus, that it will pro- 

 bably be separated and its distinct varieties established as species. 



Grows in the upper and mountainous districts of Carolina and Georgia 

 in the western districts of Georgia common. ■■ 



Flowers August — October.
