bark is red and flakes off. It is used as a remedy in dysentery. In Guam the wood 
is used for making spokes of wheels and for floors of small houses. It is fine-grained, 
heavy, hard, durable in water, and of a red or brown color. Logs 4.5 meters long 
and 30 em. in diameter may be obtained. The tree yields a resin and from the seeds 
a whitish semi-solid oil is expressed which becomes fluid at a high temperature. 
This is used in India for burning, and in some places as a hair oil.
