Thriving Epipremnum aureum

I'm not entirely sure if this plant is an Epipremnum aureum.  I do know that it is thriving!  It's grown all the way up the trunk of what was an old date palm tree.  It's now so heavy that the trunk of the old palm is being held up with a rope.  The leaves at the top are huge and many stems dangle down towards the ground.  This plant produces a really tropical feel and requires regular pruning.  The stems are so dense that you can barely see the old trunk!  By the way, the canopy was trimmed a few weeks ago.  That's why it looks so sparse.
