When I wrote "The species that has been marketed (dare I say "hyped") is Melaleuca scoparia, commonly called "Manuka" in English, from its common name in NZ, but it also occurs in Oz." I was being distracted and offer apologies to anyone misled. Manuka is Leptospermum scoparia and while various melaleucas may be commonly known as tea tree, the most commonly applied common name is 'paperbark'.
