Filaments (see fig. 1 .) 6, awl-shaped, 4 of them longer than the 
calyx, in one or two exotic species they are connate. Anthers 
somewhat heart-shaped, bluntish. Germen (see fig. 3.) egg-shaped. 
Style (see fig. 3.) vertical, dilated, elliptical, leafy, longer than the 
germen, permanent. Stigma blunt. Pouch ( siliclej (fig. 4.) swol- 
len, with a dilated, flat, winged Style, twice as long as the valves ; 
Valves (see fig. 5.) 2, concave, opening longitudinally. Partition 
(dissepiment ) broad, membranous, continued into the style. Seeds 
(see figs. 5 & 7.) few in each cell, globose, pendulous. Cotyledons 
folded together (o > > ). 
The swollen pouch, with a dilated, flat, winged style, twice as 
long as the valves; and the conduplicate cotyledons; will distin- 
guish this from other genera in the same class and order.
