PLATE IV. 



Trunk of Hydnocarpus castanea Hook. f. and Thoms. 



The bark of this tree is used by the natives in the form of a tea for internal disorders and skin 

 diseases. The string tied around the trunk enables it to be identified by the children and 

 young men who collect the bark. Although the seeds of this species are collected and sold in 

 the bazaars of Burma, nothing is as yet known regarding the composition of their fatty oil. 

 The tree shown was growing in the Martaban Hills, Kalama Range, Burma. (Photo-
