Plant about 7 feet high, glabrous. Leaves equally pinnate, the com- 
mon petiole ending in a bristle ; leaflets sprinkled with a few hairs near 
the base. Racemes 4—8 flowered. Calyx 5 toothed. Petals equal, 
yellow. Lomentum conspicuously stipitate, rigidly mucronate, with both 
sutures thickened, the two tunics of the pod separate in an unusual man- 
ner when they are mature, so that the seeds appear to be inclosed in an 
interior integument. From this circumstance Jacquin’s trivial name was 
derived, which I have retained, not only as prior in time, but perhaps 
as most appropriate. To the preceding species however, this plant is not 
allied, and after being so often removed, it has still to find an abiding 
"place. 
Grows in damp soils. Not very common, sometimes seen near Charles- 
ton- 
Flowers August— September.

pubescent.
