small entire, a little scabrous on the upper surface. Flowers small, in sim- 

 ple or compound racemes, very numerous. Scales of the involucrum linear- 

 lanceolate, acute, nearly glabrous. Florets of the ray, (about twenty) nar- 

 row, pale purple, of the disk, yellow. Seeds a little hairy. 



The plant I have described agrees very exactly with the A. Vimineus, 

 Willd: considered by Pursh, and I believe Mr. Nuttall, as a variety of A, 

 Tradescanti. I must however remark that I have a specimen sent from 

 Penn. by Dr. Muhlenberg, as the A. Tradescanti of Lin. which differs very 

 widely from this, but differs, I think alsp, from the description of Ait. and 

 Willdenow. 



Grows in the mountains of Carolina, Mich. Probably in all of the up- 

 per districts, as it is found in the same range of country in N. Carolina. 



Flowers September — October.
