Below is the same plant that is available in nursery but in a very different form --- ground-creeping version with arrowhead shaped leaves. Once it starts climbing up tree trunk, it transforms into a very different form ---- the leaves become larger and split to leaflets. As it adapts very well to the natural environment here, it is now a common climber in the wild.

Another two common gigantic climbers here that exhibit such changes in their leaves are Epipremnum aureum and Epipremnum pinnatum. A good review of such transformation can be found in the Exotic Rainforest website.
