A spreading tree with simple, oval, entire leaves, rounded or emarginate at the 
top, bearing a peculiar fruit, which consists of the enlarged, fleshy peduncle bearing 
a kidney-shaped nut. The peduncle is pear-shaped, of a yellow or reddish color, 
astringent when green, but when thoroughly ripe pleasantly acid and edible. The 
nut is oily and its shell very acrid. When roasted it is edible, the kernel acquiring 
a pleasant milky flavor. In roasting, the eyes and face should not be exposed to 
the caustic fumes which rise from the shell. A yellowish oil of a sweet flavor may 
be expressed from the kernel. The trunk and branches on being abraded yield a 
transparent gum obnoxious to insects. An acrid oily liquid derived from the shell 
is used to protect books and furniture from the attacks of insects, and in the 
Andaman Islands to preserve fishing lines. This tree, which is of great economic 
importance in tropical America, is not much esteemed by the natives of Guam. 
They sometimes eat the fruit and roast the nuts, but neither can be called a food 
staple of the island. Although introduced more than a century ago, it has not spread 
upon the island and is found only near the houses of natives, where it has been 
planted, or on the sites of abandoned ranches.
