Gen. Char. Calxjx (fig. 1.) inferior, of 4, closely converging, 
oblong, blunt, deciduous sepals, overlaying each other at the upper 
part, separating first at the bottom ; two opposite ones protuberant 
at the base. Corolla (fig. 2.) of 4, inversely egg-shaped, blunt, or 
slightly notched, obliquely spreading petals ; with strap-shaped, 
channelled, upright claws, as long as the calyx (see fig. 3). Fila- 
ments (fig. 4.) 6, thread-shaped, upright, simple, the two shorter 
with a gland at their base internally. Anthers strap-shaped, re- 
curved. Germen (see fig. 4.) 4-sided, strap-shaped, as long as the 
calyx. Style (see fig. 4.) scarcely any. Stigma nearly sessile, of 
2 upright, closely converging, blunt, downy lobes. Pod (silique) 
(fig. 5.) 4-sided, or 2-edged, striated, protuberant from the seeds; 
valves (see fig. 6.) strap-shaped, undulated, pointed, the length of 
the membranous partition. Seeds (see figs. 6 & 7.) in a single row, 
pendulous, oblong, obscurely triangular, not bordered. Cotyledons 
(see fig. 8.) flat, incumbent (o||). 
The upright calyx ; the nearly sessile stigma, with 2 converging 
lobes ; the 4-sided or 2-edged pod ; and the flat, incumbent coty- 
ledons ; will distinguish this from other genera in the same class 
and order.
