Racemes paniculate, not virgate, secund, nearly naked* 

 ly one-flowered, generally pubescent. Flowers InrgCj rays about ten. ne* 

 ceptacle punctate, margins of the alveoli pubescent. Nutl. This, I think, 

 belongs decidedly to the last division of this genus, (racemis erectis,) 



Schweinitz* .. 



Stem three to five feet high, glabrous, generally purple. Leaves sessile, 

 somewhat araplexicaule, linear-lanceolate, acute, very glabrous, succulent, 

 nerved, scabrous along the margins; the lower ones a foot in length, iw- 

 cemes paniculate, generally erect, sometimes, though rarely, recurved. 

 Flowers large. Scales of the involucrum linear, acute. Florets of the ray 

 seven to ten. Seed pubescent- - , 



I am uncertain whether the plant I have described really belongs to thi» 

 species, about which I think there exists some uncertainty. The S. Sem- 

 pervirens of Michaux evidently belongs to this species or to the S. Laeviga- 

 ta. In the S. Sempervirens I have followed the authority of Mr. Nuttali. 



As the name of Mexicana was inaccurately applied to this species, I have 

 concurred with Mr. Nuttali in restoring to it, at the suggestion of Persoottr 

 the original name of Plukenet t. 235. f. 2. i 



Grows in the neighbourhood of salt water very abundantly. 



Flowers August — October.
