Discussion

Terminalia muelleri is occasionally cultivated as an ornamental tree in southern and central Florida; it has naturalized coastally from Palm Beach County in the east to Manatee County in the west, and extending south­ward on the peninsula.

Terminalia muelleri is a triploid; polyploidy is com­mon in the genus (D. Ohri 1996; C. A. Stace 2007).
