Oncosperma filamentosum.

Botanical name: 

Oncosperma filamentosum Blume. Palmae. Nibung Palm.

Malay. This is the nibung of the Malays. The heart, or cabbage, is delicately white with a very sweet, nutty flavor. Adams says the cabbage is certainly a most delicious vegetable and, when boiled, resembles asparagus or kale; in its raw state, it furnishes fictitious cucumbers and an excellent salad.
