A shrub, climbing, a few feet in height : branches long, un- 

 armed, towards their extremities anguloso-sulcated and minutely 

 puberulous or subglabrous. Leaves biternate : leaflets unequal,

The branches of this species, from their roughness and flexi-

 toxicating fish. It is said, that those of some species of SERJANIA
