CsBsalpinia brevifolia, Bentham. (Balsamocarpon brevifolium, Clos.) 

 Chili. The pods of this shrub are extraordinarily rich in 

 tannic acid, containing up to 80 per cent., and hence valuable 

 for tanneries (Philippi). The process of tanning is accom- 

 plished in one-third of the time required for leather from oak 

 bark ; especially valuable as giving a bloom to the leather. 



Csesalpinia coriaria, Willdenow. 



Wet sea-shores of Central America. Might be naturalised in

 tree produces annually about 100 Ibs. of pods, the husk of 

 which, commercially known as Divi-Divi, is regarded as the 

 most powerful and quickly-acting tanning material in India. 

 The mercantile price of the pods is from 8 to 13 per ton.
