This is a very common plant in the state of New-York, in 
Long Island, and many parts of New Jersey and Pennsylvania, 
where we have seen it growing in great plenty on sandy banks and 
in woods. The calyx is profoundly bilabiate ; corolla papilionaceous, 
the vexillum with reflexed sides, and the keel acuminated ; stamens 
monadelphous, with the tube or sheath entire ; five of the anthers 
are smaller, rounder and earlier, and the other five oblong and later; 
style filiform ; stigma terminal, roundish and bearded ; legume cori- 
aceous, oblong, compressed, obliquely torulose ; cotyledons thick, but 
converted into leaves at the time of germination ; leaflets complicated 
before expansion, and while asleep or through the night ; stipules 
adnate to the petioles ; peduncles opposite the leaves or terminal ; 
flowers alternate or verticellate, sessile, or pedicellate, disposed in 
racemes and apikes, with one bractea under each pedicel, and with 
two bracteas adhering laterally to the calyx, which are caduous or 
wanting.
