Gen. Char. Calyx (fig. 2.) upright, equal at the base ; of 4 
oval, concave, uniform, deciduous sepals. Corolla (see fig. 3.) of 
4 inversely egg-shaped, entire, spreading petals (see fig. 4.), their 
claws not so long as the calyx. Filaments (see figs. 3 & 5.) 6, 
simple. Anthers of two round lobes. Germen (fig. 6.) egg-shaped, 
compressed. Style none. Stigma fiat, quite sessile. Pouch (figs. 7 
and 8.) oval, transversely compressed, entire, tipped with the 
stigma, of 2 cells and 2 valves; valves (see fig. 8.) deeply concave, 
boat-like, but not keeled; dissepiment ( partition J membranous, 
elliptical, parallel to the valves, but crossing the narrowest diame- 
ter of the pouch. Seeds (see figs. 8 & 9 ) 4 or more in each cell. 
Cotyledons (see fiir. 10.) incumbent (o||), strap-shaped, curved. 
The oval, pointless, many-seeded pouch ; the tumid valves ; and 
the strap-shaped, curved, incumbent cotyledons ; will distinguish 
this from other genera in the same class and order.
