A. Undulatus. Sp. pi. 3. p. 2035. Pursh, 2. p. 551. Nutt. 2. p. 156. 
A. Tardiflorus? Walt. p. 210. 
Stem about three feet high, pubescent, scabrous, diffusely branched near 
the summit. heaves generally entire, sometimes slightly toothed; the 
petiole of the lower ones winged, dilated at base, amplexicaule — those of 
the branches very small, all very pubescent underneath, slightly scabrous 
on the upper surface. Flowers of a middling size, in a long terminal pani- 
cle. Leaves of the involucrum numerous, lanceolate, pubescent, fringed. 
Florets of the ray from twelve to fifteen, pale purple; of the disk twenty- 
four, yellow, changing as they decay to purple. Seeds slightly angled, a 
little hairy. 
Grows in dry soils, very common. 
Flowers September — November.

A. foliis oblongo- 
lanceolatis, sessilibus, 
medio serratis, sub 
glabris, radicalibus ob- 
Iongis,cordato-sagitta- 
tis, serratis, petiolatis; 
caule ramoso, glabro; 
involucris laxis, imbri- 
catis. 
Leaves oblong-lan- 
ceolate, sessile, serrate 
in the middle, rather 
glabrous, those of the 
root oblong, cordate, 
sagittate, serrate, pe- 
tiolate; stem branch- 
ing, glabrous; involu- 
crum loose, imbricate. 
Sp. pi. 3. p. 2035. Pursh, 2. p. 551. Nutt. 2. p. 156. 
Stem two to three feet high, erect, glabrous, bearing many branches. 
Leaves of the root oblong, unequally serrate, cordate and sagittate at base, 
glabrous, two inches long and upwards, on naked petioles; lower stem 
leaves oblong, ovate, acuminate, coarsely serrate, on winged petioles, the 
upper oblong-lanceolate, acuminate, sessile, serrate in the middle, the high- 
est entire. Floivers of a middling size, peduncles leafy. Scales of the in- 
volucrum lanceolate, loosely imbricate. Willd. 
The plants which I have examined as belonging to this species have their 
leaves slightly scabrous and pubescent along the veins, and nearly entire, 
thinner however and more glabrous than those of A. Diversifolius to which 
they are nearly allied. 
Grows in the upper districts of North and South-Carolina. 
Flowers September— October.
