I spotted quite a few trees with leaves like these plastered to their trunks. After some searching, I believe this is probably a plant in the Monstera genus. This adhesive climbing behavior is known as shingling. Interestingly, the leaves of the grown plant take on a very different form (follow the wikipedia link above).
