Root perennial. Stem two to three feet high, glabrous, with the branched 
expanding. Leaves sessile, those of the stem about an inch and half long, 
acute at each end, those of the branches very small, appressed; all glabrous 
but scabrous along the margins. Panicle compound, the branches generally 
few flowered. Involucrum imbricate, scales acute, appressed, hairy or 
fringed at the summit. Florets of the ray twenty to twenty-four, linear- 
lanceolate, pale purple; of the disk about thirty, yellow. Style scarcely as 
long as the stamens. Seed glabrous. Pappus somewhat scabrous. 
The plant I have described is certainly the A. Coridifolius of Michaux, 
It appears to differ in some respects from the A. F oiiolosus of Ait. 
Grows in dry soils. 
Flowers September-— October.

Nearly glabrous; 
leaves linear, entire, 
reflexed; stem slender, 
much branched; the 
branches expanding, 
setaceous, one-flower- 
ed; scales of the invo-

This species I have not noticed and perhaps as suggested by Mr. Nuttall, 
it is only a variety of the A. Foliolosus. The A. Flexuosus of Nuttall, A. 
Geniculatus, Hamilton, was considered by Dr. Muhlenberg, as well as 
Pur$h, to be the A. Sparsiflorus of Michaux. 
Grows in the low country of Carolina. Mich.
