 macapuno, a sport fruit of the coconut which instead of containing water is

 normal coconuts. Thus far no way is known of distinguishing normal fruit 

 from macapuno fruit, except by shaking the fruit. It has been observed, 

 however, that the trees which bear macapuno nuts will continue to do so from 

 year to year.
