persistent leaves attached to the base of the calyx and forming in some 
measure an exterior calyx, the proper calyx is split on the under side^ to 
the base, the border 5 cleft, the 2 lateral lobes round, the intermediate 
longer and acute. Corolla of an obscure yellow, with brighter streaks and 
spotted with purple and brown, border 5 cleft, the 2 upper segments re- 
flected, the 3 lower expanding. Stamens shorter than the corolla which 
contains also the rudiment of a filth filament. Style longer than the sta- 
mens, dilated towards the summit. Stigma two lobed, compressed, pos- 
sessing some irritability. Capsule rather large, with the surface furrowed 
like bark, tapering to the summit and each valve terminating in an incurv- 
ed beak 2 — 3 inches long. Seeds ovate, covered with a pulpy coat. 
Grows in dry soils, about buildings, Beaufort, Columbia, generally dif- 
fused but I suspect not indigenous. 
Flowers June — August.
