Gen. Char. Calyx (figs. 1 & 2.) inferior, equal, and nearly flat 
at the base ; of 4, oblong, straight, spreading, deciduous sepals. 
Corolla (see fig. 2.) cruciform, of 4, inversely egg-shaped, rounded, 
entire, or slightly notched, spreading petals, with strap-shaped, up- 
right claws. Filaments (see fig. 4.) 6, awl-shaped, simple, upright. 
Jinthers oblong, slightly spreading. Glands (see fig. 4.) 4 ; 2 at 
the inside of the shorter filaments, 2 at the outside of the longer. 
Germen (see figs. 4 & 5.) cylindrical, tapering into a short style. 
Stigma capitate, rather small. Pod (see figs. 6 & 7.) nearly cylin- 
drical, or somewhat 4-angled, variously beaked, of 2 concave, 
undulated valves, and 2 longitudinal cells, besides 1 for the most 
part in the beak, generally barren. Seeds in a single row, nearly 
globular (see figs. 8 & 9), with 1 occasionally in the heak. Coty- 
ledons conduplicate, their double edges meeting the radicle (o> > ). 
The spreading calyx ; the nearly cylindrical, somewhat beaked 
pod, of 2 valves ; and the conduplicate cotyledons ; will distinguish 
this from other genera in the same class and order. 
Five species British. 
SINA'PIS NI'GRA. Black Mustard. Common Mustard. 
Spec. Char. Pods somewhat 4-angled, smooth, even, slightly 
beaked, close-pressed to the stalk. Lower leaves lyrate ; upper 
strap-spear-shaped, quite entire, stalked, smooth.
