1 Lamarck first properly distinguished from Eryngium aquaticum, Linn., the var. 

 p., and characterized it as a distinct species, under the name of E. Virginianum. 

 Later, Michaux, giving to the original E. aquaticum of Linnceus the name of E. 

 yuccccfolium, descrihed under the name of E. aquaticum, a plant which appears to 

 he, not the E. Virginianum of Lamarck (which is described as only a foot or so in 

 height, with long and narrow, ensiform, radical leaves, finely striate and ciliate, 

 with distant spinules, Lamarck moreover citing the figure of Pluk. Aim. t. 396), 

 hut the much larger and broader-leaved plant which Elliott has well characterized 

 under that name. Elliott's E. Plukenetii is truly E. Virginianum, Lam. I am 

 indebted to H. W. Ravenel, Esq., of St. Johns, Berkley, S. Carolina, for full speci- 

 mens and notes, accurately distinguishing these species, and another, which perhaps 

 has also been confounded with E. Virginianum, hut which may properly bear the 

 name of this acute and zealous botanist, who has directed my attention to its char- 

 acters. The latter should stand next E. aquaticum, L.
