what name to give to this tree?

in the plant kingdom, hybrids created by crossing one species of palm with another is not uncommon. but a cross between a coconut palm and a ficus tree, that is unheard of.

what name should be given to this tree? it has the trunk of a coconut tree but the foliage is that of a ficus tree. i am not sure of the variety of the ficus.

this tree caught my eyes as i was stuck behind a line of vehicles waiting for the light to change just before the train crossing at kranji.
