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 ; 

 floicers alternate or verticellate, sessile, or pedicellate, disposed in 

 racemes and spikes, with one bractea under each pedicel, and with 

 two bracteas adhering laterally to the calyx, which are caduous or 

 wanting.
