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 
proved by the prototype specimen, found by Mr. Bradberry 
in another part of Louisiana, and now in Mr. Lamberts, 
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; leaflets 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, lanceolately elliptic, bluntish, 
with a small point, tapered towards the petioles. Pedunciés 
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 3 of an inch long; ôractes linear, subulate, 
ubescent, not equal to the calyx. Calyx about half the 
length of the corolla with a. brown shaggy nap, purplish- 
green, with small pointed even teeth. Corolla pale violet- 
purple; veri/lum rather longer than the wings, ovate, ob- 
long, notched at top; wings. falcate; keel shorter than the 
wings, inflectent, ventricose,-obtuse, notched, of a deep 
bright colour. Anthers orange-yellow. Germen green, 
smooth, round, several.seeded, shorter than the white in- 
flectent style: stigma slightly thickened, smooth, obtuse, 
Pod, when ripe, about thesizeof a nutmeg, not unlike a 
stinted walnut; shell bilocular, fungously cartilaginous, con- 
tracted into furrows, divided outwards by a prominent 
suture; inwards by a double entire dissepiment of the sub- 
stance of parchment: secds several in each cell.
