It's possible you're thinking of a tree that has a different name, or a local, regional, or informal name for a tree. Could you provide more information?
Perhaps you could tell me:
* Where you heard the name "Wawa Tree": Was it a specific location, a book, or a conversation?
* What the tree looks like: Any notable features, like leaf shape, bark texture, or flower color?
* What the tree is used for: Does it have any medicinal or cultural significance?
With more information, I can help you identify the correct scientific name for the tree you're thinking of.
