Oncosperma tigillarium Nibung PALMAE. You can find Nibung Palm at the zoo too. The tree can grow up to 25 metres and is found in brackish water swamps. The timber is durable even when in constant contact with water and therefore suitable as building material for kelong or fish traps. The spines are used by tribal people to make blowpipe darts. Monkeys brave the thorny trunks to get to the flowers and feast on them.
