It is also reportedly naturalized in Mauritius, the Chagos Arhipelago, Puerto Rico and the Leeward Islands.[1]

Preparing to collect sap at Jessore, Bangladesh

Growing in plains and scrubland to 1300 m, the fruit from this palm species is used to make wine and jelly. The sap is tapped and drunk fresh or fermented into toddy. The fresh sap is boiled to make palm jaggery in West Bengal state of India and Bangladesh.

The plant is known as "Wal Indi", "val Indi",(වල්ඉංදි ) by Sinhalese people in Sri Lanka. The word `Phoenix`in the Latin name came from Greek and means "purple". while `Sylvestris` means "wild". The leaves may be used for making mats, bags etc. The tree is tapped to make a toddy or palm wine.
