Nypa fruticans
As the only true mangrove palm species, any palm-like trees you see growing in the mangroves is a Nipah palm. However, they do not tolerate salinity as well as other species of mangrove trees, so they typically thrive more inland, where the waters have lower salt content.
Unlike other palm trees which possess an upright stem, the only visible part of the Nipah is their fronds (leaves). Their stems grow horizontally underground, and branches in a Y-shaped pattern.
The Nipah palm used to be a highly commercially valuable plant species and are used to make brooms, roof thatchings, and even syrup! However with industrialization and mass production of alternatives such as synthetic fibers, corrugated zinc sheets and white sugar, the industry surrounding the Nipah palm has been largely relegated to the annals of history.
