Baot perennial. Stem three to four feet high, slightly furrowed, pubes- 

 cent, bearing very many virgate branches. Leaves alternate, sessile, three- 

 nerved, scabrous and covered with a fine somewhat tomentose pubescencej 

 the lower nearly trifoliate, having two small lateral leaves at the base; the 

 middle leaflet lanceolate, sometimes deeply notched, sometimes entire; the 

 upper leaves lanceolate, entire. Leaves of the involucrum linear-lanceo- 

 late, or subulate, tomentose and deflected. Florets of the ray about eight, 

 yellow, two-cleft at the summit, three times as long as the involucrum. Flo^ 

 rets of the disk very numerous, of a brownish yellow. Seed four-angled; 

 pappus obsolete, the summit of the seed slightly toothed. Receptacle ob- 

 long, oval, chaff truncated, longer than the seed, tomentose at the summit. 



I am uncertain whether this is the R. Subtomentosa of Mich, and Pursh. 

 It is a very distinct species from the R. Triloba, to which in fact it has no 

 resemblance but in its tripartite leaves. 



Grows in the western districts of Georsria.
