The Jamaican Star Apple

The star apple tree Chrysophyllum cainito is a native of the Caribbean and Central America. It is a member of the Sapotaceae family which includes over 150 species of tree found in tropical and sub-tropical regions.
In Jamaica, it is fairly common and well known for the luscious fruit and its use as a shade tree. A mature tree attains a height of over 15 metres with a trunk of nearly a metre in diameter.
