nevertheless, from three projecting dots on its sides, 
to have a triangular appearance. Under a powerful lens, 
it will be distinctly seen that these three seeming dots 
represent three vertical projecting ribs, by which the pollen 
is banded, very much as the capsules of some Orchideæ. 
Leaves bipinnate, downy; leaflets with an odd one, 
ovate-rhomboid, acute, very unequal; the lower ones very 
small, and rounder than the others. Peduncles axillary, 
3-flowered, downy, with little bracteole. Calyx campanu- 
late, obtuse at the base, 5-toothed; teeth short, ovate, 
equal. Corolla dark-purple, downy externally, with a 
short tube, not more than twice the length of the calyx; 
limb tubular-campanulate, 14 inch long, arcuate, with 
retuse, nearly equal segments, and a pale spot under 
the upper lip. Stamens 4, didynamous, the fifth being 
sterile, filiform, subclavate, nearly as long as the limb, and 
bearded ; filaments smooth, with a few glandular hairs at 
the base; anthers 2-celled, with very spreading cells, which 
are acuminate at the base. Pollen fuscous, spherical, 
confined by three projecting bands, whence it seems as if 
3-cornered.
