I have a similar one which we call "Spider." the parent tree for my cutting is or was in Veracruz, MX. For me it blooms well but doesn't multi tip branch well. It also is a prolific seed pod producer. I don't remember the specific scent but I think it's rather light.

Since you don't know for sure, it will always be a noid. It looks very much like Ammaron's curly white, though. The petals on ACW arent always super twisty like many photos show. What is the scent of yours? It's very pretty!
