A. Tardiflorus? Walt, p. 210. 



Stem al)out three feet high? pubescent, scabrous, diffusely branched near 

 the summit- Leaves generally entire, sometimes slightly toothed; the- 

 petiole of the lower ones winged, dilated at base, amplexicaule — those of 

 tlie 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 hairv. 



Grows in dry soils, very common. 

 Flowers September — November.

Stem two to three feet high, erect, glabrous, bearing many branches. 

 Leaves of the root oblong, unequally serrate, cordate and sagittate at base, 

 tjlabrous, two inches long and upwards, on n;tked petioles: lower stem 



leaves oblong, ovate, acuminate, coarsely serrate, on winged petioles, 

 upper oblong-lanceolatcj^acuminate, sessile, serrate hi the middle, the high* 

 est entire. Flowers 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. 



Growls in the u{)per districts of North and South-Carolina. 



Flowers September — October*
