Root perennial. Stem two to three feet high, glabrous, with the branches 

 expanding, leaves sessile, those of the stem about an inch and half long, 

 acute at each end, those of the branches very small, appressedj 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. Foliolosus of Ait. 



Grows in dry soils. 



Flowers September — October.

This species I have not noticed and perhaps as suggested by Mr. ^^J'^!^' 

 it is only a variety of the A. Foliolosus. The A. Flexuosus of Nuttall, A. 

 Geniculatus, Hamilton, was considered by Dr. Muhlenberg, as «^ell a? 

 Pursh, to be the A. Sparsiflorus of Michaux. ' 



Grows in the low country of Cajolina. Mich.
