Roystonea is a genus of eleven species of monoecious palms, native to the Neotropics, in the Caribbean, the adjacent coasts of Florida in the United States, Mexico, Central America and northern South America.[3][4][5] Commonly known as the royal palms, the genus was named after Roy Stone, a U.S. Army engineer. It contains some of the most recognizable and commonly cultivated palms of tropical and subtropical regions.
