SYNGENESIA SUPERFLUA. 
** Racemis erectis. | ** Racemes erect. 
21. Limojnifolia. Persoon. 
S. caule obliquo, 
glabro; foliis lanceola- 
tis, subcarnosis, inte- 
gerrimis, undique lae- 
vibus; racemis panicu- 
latis, erectis; peduncu- 
lis squamosis, giabris; 
ligulis elongatis. 
Stem oblique, gla- 
brous; leaves lanceo- 
late, somewhat car- 
nose, entire, smooth on 
both surfaces; racemes 
panicled, erect; pedun- 
cles scaly, glabrous; 
florets of the ray long. 
Persoon. Syn. 2. p. Nutt. 2. p. 159. 
S. Mexicana. Sp. pi. 3. 2063. Pursh, 2. p. 541. 
Racemes paniculate, not virgate, secund, nearly naked. Peduncles most- 
ly one-flowered, generally pubescent. Floiaers large, rays about ten. Re- 
ceptacle punctate, margins of the alveoli pubescent. Nutt. 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 amplexicaule, linear-lanceolate, acute, very glabrous, succulent, 
nerved, scabrous along the margins; the lower ones a foot in length. Ra- 
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 this 
species, about which I think there exists some uncertainty. The S. Sem- 
per virens of Michaux evidently belongs to this species or to the S. Laeviga- 
ta. In the S. Sempervirens I have followed the authority of Mr. NuttalL 
As the name of Mexicana was inaccurately applied to this species, I have 
concurred with Mr. Nuttall in restoring to it, at the suggestion of Persoon, 
the original name of Plukenet t. 235. f. 2. 
Grows in the neighbourhood of salt water very abundantly. 
Flowers August — October.
