Stem simple, terete, leafy, eighteen inches high. Leaves two to four in* 
ches long, two to four lines wide, attenuated at base. Flowers about eight 
to ten, small and pale yellow. Pappus double? Nutt. 
This species I have not noticed. The E. Carolinianum of Linnaeus to 
which I was accustomed to refer the E. Strigosum of this sketch, and to 
which Mr. Nuttall alludes under this species, if established on the figure of 
Dillenius, (Hort. Elth. t. 306. f. 394.) belongs, I think, unquestionably to 
another genus. 
Grows in Georgia.
