Borrichia arborescens grows in the Florida Keys, Bermuda, and the West Indies, including Jamaica and Guadeloupe. Plants of B. arborescens are usually glabrous; both glabrous and hairy plants occur in the northern West Indies. Common names that include “tree” are misleading because the plants are shrubs.
