 ■ Stem 2 to 3 feet high, smooth, glabrous ; leaves generally opposite, two 

 to four inches long, glabrous, coarsely toothed, on petioles two inches long. 

 Involucrum ten to twelve-leaved, twelve to sixteen-flowered ; leaves linear- 

 lanceolate, finely pubescent, nearly equal in length. Corolla white. Style 

 longer than the corolla. Seeds angled, glabrous. Pappus shgMy scabrous. 



I feel doubtful whether the plant I have described is the E. Ageratoides ot 

 Muhl.; it certainly is the E. Urticaefolium of Mi^h. and its leaves bear o 

 striking resemblance to those of the Urtica, ' "- ^ " '" -""'

This plant is certainly the E. Aromaticum of Michaux, and E. L^oraai 

 of Walter. Whether it is the E. Aromaticum of Linnaeus and Gronovius ; 

 I thinl;, questionable ; it does not resemble tlie figure referred to in Pluken 



t. 88. f. 3. 



Grows in rich dry soils.
