volume comprises the present species, which was found in 
Upper Louisiana by Mr. Nuttall, by whom it has been 
lately introduced into this country. Mr. Pursh, who knew 
it only by the name we have cited from Fraser’s Catalogue, 
had surmised it to be the same with the carnosus of the 
Supplement to his American Flora, But that is a very 
distinct plant with numerous spreading branches, terminal 
sessile spikes, and a lignescent or suffrutescent stem; ‘as 
roved by the prototype specimen, found by Mr. Bradberry 
i another part of Louisiana, and now in Mr. Lambert’s 
Herbarium. Gum Tragacanth is a secretion of more than 
one species in the Levant. 
Our plant is perennial, tolerably hardy, herbaceous, and 
covered by a hoary.nap. Stems several, first procumbent, 
then ascending, simple, with a waved appearance. Leaves 
alternate, patent, distant; Jeaflets mostly opposite, 17-25, 
or thereabouts, expanded, placed at open intervals, shortly 
petioled, smooth on the upper surface; with a closely press- 
ed nap on the under; about half an inch long, and about 
three times narrower across, lanceéolately elliptic, bluntish, 
with a small point, tapered towards the petioles. Peduncles 
axillary, twice as, long.as) the spikes or longer, equalling or 
overtopping the leaves. Racemes (spikes) 8-14-flowered, 
glomerate, or sometimes extended and loose; flowers almost 
sessile, about 2 of an inch long; dractes linear, subulate, 
pubescent, not equal to the calyx.  Calyw about half the 
Jength of the corolla with a brown shaggy nap, purplish- 
green, with small pointed even:teeth. Corolla pale violet- 
purple; vevillum rather longer than ‘the “wings, ovate, ob- 
long, notched at top} ‘wings’ falcate; ‘keel shorter than the 
wings, inflectent, xentricose, obtuse, notched, of a deep 
bright colour. .., duthers orange-yellow: Germen_ green, 
smooth, round, several-seeded, shorter’ than’ the. white in- | 
flectent style: stigma slightly thickened, smooth, obtuse, 
Pod, when ripe, about..the size of a nutmeg, not unlike a 
stinted walnut; shell bilocular;*fungously cartilaginous, con- 
tracted into furrows, «divided -out\ards by’ a prominent 
suture; inwards by a double. entire dissepiment of the sub- 
stance of parchment: seeds severalan:each: cell.
