Nypa fruticans, commonly known as the nipa palm or mangrove palm, is a species of palm tree that belongs to the family Arecaceae. It is unique among palm trees as it is adapted to grow in mangrove ecosystems. Nypa fruticans is primarily found in the coastal regions of Southeast Asia and the Pacific Islands.

The nipa palm has a distinctive appearance, with a stout trunk that can reach up to 30 meters in height. Its leaves are large and fan-shaped, arranged in a dense crown. The palm produces large clusters of small, yellowish flowers and edible fruit that resemble coconuts.

Nypa fruticans is well adapted to the saline and waterlogged conditions of mangrove swamps. Its specialized root system allows it to anchor firmly in soft and unstable soil. The palm also has unique adaptations for water and gas exchange, such as pneumatophores (root-like structures) that protrude from the soil to access oxygen.

Nypa fruticans provides various ecological services in mangrove ecosystems. It helps stabilize coastlines, protects against erosion, and provides habitat for a diverse range of organisms, including birds, crabs, and fishes. Additionally, the palm has traditional uses in local communities, with its leaves used for thatching, weaving, and other crafts, while its sap can be tapped to produce a sweet syrup or fermented for alcoholic beverages.
