Gen. Char. Calyx (see figs. 1 & 2.) inferior, equal at the base, 
of 4 egg-shaped, concave, moderately spreading, deciduous sepals. 
Corolla (see fig. 2.) of 4 inversely egg-shaped, equal, entire petals, 
(fig. 3.) their claws short and broad. Filaments (fig. 4.) 6, 2 of 
which are shorter than the other 4 (tetradynamous), simple, slender. 
Anthers heart-shaped. Germen roundish, compressed. Style short. 
Stigma blunt. Pouch or Silicte (fig. 5.) laterally compressed, tri- 
angular, wedge-shaped at the base; with sharply keeled, wingless 
valves; cells many-seeded. Partition ( dissepiment ) (see fig. 6.) 
elliptic-spear-shaped, crossing the greater diameter of the pouch. 
Seeds (see fig. 6.) several, fixed to both sides of the placenta by an 
umbilical thread, pendulous. Cotyledons flat, incumbent, (o||). 
The triangular pouch, wedge-shaped at the base; the sharply 
keeled, wingless valves ; and the manv-seeded cells; will distin- 
guish this from other genera, wish incumbent cotyledons, in tlie 
same class and order. — It differs from Thlaspi in the valves not 
being winged at the back ; and in the cotyledons being incumbent., 
not accumbent. 
Only one species known.
