Gen. jChar. Calyx (fig. 1.) inferior, tubular, cut about half 
way down, into 5, strap-shaped, taper-pointed segments, shorter 
than the corolla ; the lowermost rather the longest. Corolla (see 
fig. 2.) of 5 petals ; standard (see figs. 2 & 3.) largest, inversely 
egg-shaped, slightly reflexed ; wings (fig. 5.) half as long, blunt; 
keel (fig. 4.) nearly equal to the wings, rounded, with a sharp point, 
of 2 combined petals, with separate claws. Filaments (see fig. 6.) 
10 ; 9 united into a compressed tube, open at the upper edge ; the 
tenth hair-like, distinct, closing the fissure. Anthers small, round- 
ish. Germen (fig. 7.) oblong, compressed. Style (see fig. 7.) cy- 
lindrical, half as long, ascending at a right angle. Stigma termi- 
nal, capitate, downy all over. Legume (fig. 8.) oblong, compressed, 
bluntish, tumid only from the projection of the seeds, which are 
from 2 to 4, roundish, a little flattened (fig. 9). 
The smooth style ; the capitate stigma, hairy all over ; and the 
2- or 4-seeded legume ; will distinguish this from other genera, 
with diadelphous stamens, in the same class and order.
