Gen. Char. Calyx (fig. 1, a.) inferior, of 4, egg-shaped, con- 
cave, spreading sepals, equal at the base, deciduous. Corolla (see 
fig. 2, b.) cruciform, of 4, inversely egg-shaped, entire, spreading 
petals, twice the length of the calyx, with short claws. Filaments 
(see fig. 2, c. and fig. 3.) 6, 2 shorter than the other 4, awl-shaped, 
toothless, incurved, as long as the calyx. Anthers roundish. German 
(see fig. 2, d. and fig. 3.) roundish. Style very short, permanent. 
Stigma blunt. Silicula. (pouch) (fig. 5.) sessile, globose, egg- 
shaped, or oblong, turgid, rugged, veiny, tipped with the style, of 
2 cells, and 2 concave, ventricose, scarcely keeled, valves ; partition 
orbicular or oblong, membranous, generally as wide as the valves 
(see figs. 6 & 7). Seeds (see figs. 0, 7, & 9.) many, not bordered. 
Cotyledons (fig. 8.) flat, accumbent (o=). 
The spreading calyx ; simple filaments ; nearly entire pouch, 
with ventricose valves ; and numerous, not bordered seeds ; will 
distinguish this from other genera, with accumbent cotyledons, in 
the same class and order. 
Five species British.
