oblong, blunt, spreading, somewhat coloured, deciduous sepals.

petals, tapering into short claws (see fig. 2.) ; sometimes wanting. 
Filaments (see fig. 3.) 6, awl-shaped, simple ; the 2 shortest each 
with a gland at the base wilhinside. Anthers incumbent, somewhat 
heart-shaped. Germen (fig. 4.) cylindrical. Style upright, short, 
cylindrical. Stigma blunt, notched. Pod (fig. 5.) nearly cylin- 
drical, (sometimes short) ; valves (see fig. 6.) concave, neither

The spreading calyx, equal at the base ; and the nearly cylindri-
