 ing, densely radiculose. Leaves scarcely wider than the stem, 

 somewhat distant, subdistichous, erecto-patent, broadly and ob- 

 tusely complicate-concave, under pressure broadly cuneate-triradi- 

 ate, distinctly serrate-denticulate, i-bifid; sinus broad and obtusieh 

 or sometimes acutish, lobes triangular-ovate, acute; areolation mi- 

 nute, for the most part quadrate, with the interstices narrow and 

 hyaline. Involucral leaves 3, J-connate, 2-3(?) lobed, spinulose-

J. LESCURIANA. (li. S.) 



On the ground in open woods. Orange county, C. F. Austin. 



" This is a larger species than the last with longer and more en- 

 tangled sterile stems and subulate, sub-squarrose amphigastria. 

 Fertile stems more clavate, erect, and crowded. Leaves more im- 

 bricated and the lobes more ovate, the lower not serrate. Livolu- 

 cral leaves numerous and crowded into roseate or capitate heads 

 which are at first terminal, but at length dorsal, the inner ones 

 highly connate, scarious and eroded-denticulate on the margin above. 

 Perianth broadly oval, nearly white, strongly and acutely plicate, 

 and even in the young state deeply laciniate-lobed; the motfth denticu- 

 late. The leaves towards the apex of the fertile stems are less 

 deeply bifid than the lower ones and often 2-5 papillate-dentate at 

 the subtruncate apex of die lobes." Austin MSS.
