with pulp inside, linear, rather compressed, swollen above the 

 seeds, and at length separable into 1 -seeded divisions. Un- 

 armed or prickly trees or shrubs, with bipinnate leaves, having 

 from 1 -4 pairs of pinnae, each pinna bearing many pairs of ob- 

 long-linear leaflets, and pedunculate elongated axillary spikes of

 or yellow. The pulp in the pods of all the species is eaten by 

 the natives in the various countries of their growth. The peri- 

 carp almost entirely consists of tannin.
