Pimenta dioica
Allspice
Introduced and now reproducing on its own in the wild.
Allspice, also called pimenta, Jamaica pimenta, or myrtle pepper is the dried unripe fruit (berries, used as a spice) of Pimenta dioica, a midcanopy tree native to the Greater Antilles, southern Mexico, and Central America, now cultivated in many warm parts of the world. The name "allspice" was coined as early as 1621 by the English, who thought it combined the flavour of cinnamon, nutmeg, and cloves.
