With regard to paperbark and paper bark. My understanding is that it is a paperbark tree; it's common name in Australia. However when referred to as a tea tree with the addition of paperbark in the name, then the norm is, "paper bark tea tree".
I would think both terms are correct, but of course the proper scientific name(s) are something else again.
