the ray (fourteen) lanceolate, nerved, yellow, about an inch long; of the 
disk numerous, tubular, dark purple. Seeds oblong, four-angled, compress- 
ed, a little hairy on the summit, crowned with two long, fringed, deciduous 
awns. Receptacle convex, chaffy, the chaff nearly as long as the corolla, 
concave, keeled, three-cleft at the summit, the middle segment long and 
with the keel fringed. 
Grows generally in dry soils. 
Flowers September — October. 
2. Sparsifolius. E. 
Stem scabrous, the 
branches nearly gla- 
brous; leaves ovate, 
acute, coarsely toothed, 
hispid, very scabrous 
on both surfaces, ab- 
ruptly contracted into 
a petiole; scales of the 
involucrum oval-lance- 
olate, ciliate; disk dark 
red. 
To the H. Atrorubens this plant bears a strong affinity. It is larger, 
however, and its leaves instead of tapering to the base with a slight acumi- 
nation, abruptly terminate on hispid petioles two to three inches long; they 
are broader also, much more rough, particularly on the under surface, and 
•are coarsely and irregularly toothed. 
Stem four to five feet high, with long slender generally smooth branches. 
Leaves opposite, distant, the upper nearly sessile. Flowers in a loose scat- 
tered panicle. Florets of the ray about fourteen, bright yellow; of the disk 
numerous, dark purple. Leaves of the involucrum about as long as the 
disk, finely fringed. Pappus subulate. Chaff of the receptacle lanceolate, 
nearly entire. 
Grows in the western districts of Georgia. 
Flowers August — October.
