each extending beyond the tip in a minute, 

 bristly point. Flowers numerous and very 

 showy, on long terminal racemes, the 

 corollas purplish blue, sometimes white; 

 shaped like pea-blossoms, with standard 

 turned backward at the sides, the wings 

 united and enclosing the small, curved 

 keel ; stamen tube not cleft, its anthers 

 of two forms ; style incurved ; calyx two- 

 lipped and deeply toothed. Pods broad, 

 flat, very hairy, about an inch and a half 

 long, two-valved, splitting in spiral coils 

 at maturity and flinging to some distance 

 the four or five seeds contained ; these 

 have long vitality, often remaining dor-

 seeds are also said to be very unwhole- 

 some for grazing animals, though not so 

 dangerously harmful as those of its west- 

 ern relatives.
