最初是從, Greece, Turkey

Eight subpopulations are found on the Greek Island of Crete, with the largest at Vai containing a few thousand individuals, and four subpopulations occur along the southwest coast of the Datça Peninsula, Turkey. The Cretan data palm prefers to grow in the damp sandy beds of valleys and temporary streams, but it can also be found on rocky ground. It tends to grow fairly close to the sea, and does not occur above an altitude of 250 metres.
