Arenga obtusifolia - Lankap, Palm Heart(Vegetable), Sumatra Sugar Palm
Note - The name label under this palm was labelled as Arenga westeroutii (Lankap) however the name Arenga obtusifolia had been written on the label and dated 28/10/2010.
I have assumed this is an official change but it could well have been written by someone who disagreed with the ID on the original label.
