Indies and other parts of the American Tropics. The tree is rather 

 slender in habit, with a straight trunk and compound leaves composed of 

 three or more pairs of elliptic to obovate leaflets 3 or 4 inches in length. 

 The fruits are produced in small clusters; in general appearance they 

 suggest large loquats, the surface being straw colored and slightly downy. 

 The skin is thick and leathery and does not adhere to the white trans- 

 lucent flesh, which separates into five segments. Each segment normally 

 contains an oval seed, but some of the segments in each fruit are usually 

 seedless. The flavor is highly aromatic, at times slightly pungent. The 

 fruit is commonly eaten while fresh, but it is said also to be utilized in 

 various other ways." (Wilson Popenoe.)
