Gen. Char. Calyx (figs. 1 & 2.) inferior, nearly equal at the 
ba°e, upright ; of 4 oblong, concave, somewhat coloured, decidu- 
ous sepals. Corolla (fig. 3.) cruciform, of 4 inversely egg-shaped, 
blunt, undivided, flat petals ; their claws (see fig. 4.) nearly as long 
as the calyx. Filaments (see fig. 5.) 6, awl-shaped, simple, dis- 
tinct, upright, with a gland at each side between the two shorter 
ones and the pistil. Germen (see fig. 5.) oblong, quadrangular. 
Style (see figs. 5 & 6.) short, cylindrical. Stigma blunt, simple. 
Pod (figs. 6 & 7.) 4-angled, and somewhat 2-edged ; valves con- 
cave, heeded, even and straight ; partition (see fig. 8.) membra- 
nous, thick-edged. Seeds (see fig. 8.) ranged alternately, in a 
single row, egg-shaped, flattish, not bordered ; cotyledons flat, 
accumbent (o=), see fig. 10. 
The upright calyx ; the 4-angled, slightly compressed pod ; the 
seeds in a single row ; and the two shorter filaments with glands 
at the inside, between them and the pistil ; will distinguish this 
from other g nera, with flat accumbent cotyledons, in the same 
class and order. 
Two species British.

Winter-cress. Yellow Rocket. Herb St. Barbara. Winter Hedge- 
mustard.
