Ethnobotany:The black material surrounding these seeds was once used to caulk the seams of boats leading to the name pitch apple. The leathery leaves can be scratched with the scratches remaining on the leaves until they fall -- thus autograph tree.
General Comments:

This Florida native has been introduced into Hawaii where it is extremely invasive. In fact, it has earned the distinction of being listed in the Global Compendium of Weeds.

In Florida, it is known to naturalize into areas near where it has been planted.   Avoiding the use of this in landscape settings where it could escape is recommended.
