Note
|
The legumes and bark of this tree are relatively rich in tannin, the pods report- edly having as much as 30 per cent tannin content. Besides being utilized locally in the preparation of dyes and inks, the pods are an item of considerable export interest from the tropical countries, especially the north coast of South America. The matured pods usually appear in the trade under the name "divi-divi," a com- mercial source of tannin for many years.
