Vegetation Community(-ties) disturbed/anthropogenic, open forest, shrubland
Common Name Coconut, Narel
Habitat Notes Now pantropical, especially along tropical shorelines, According to Purseglove (1968-1972), the center of origin of cocoid palms most closely related to coconut is in northwestern South America. At the time of the discovery of the New World, coconuts (as we know them today) were confined to limited areas on the Pacific coast of Central America, and absent from the Atlantic shores of the Americas and Africa. Coconuts drifted as far north as Norway are still capable of germination.
