I know Im not going to be able to convince you based on past experience but what youve done will probably do more harm than good Almost no one is familiar with the name Acer floridanum and despite the fact that recent publications suggest that Acer floridanum might be preferable the conclusion of that paper wasnt entirely confident as I recall its a bit premature to be moving it Aside from the one publication in a relatively unimportant botanical journal there isnt much supporting the name Its not considered accepted by the vast majority of sources including ITIS which I think is our standard Besides the taxonomy of the species is simply too volatile to be moving it around DNA work could reveal tomorrow that its a variety of sugar maple Its best to wait until a name is more or less universally accepted I would wait until the publication of volume  of the Flora of North America which will include the Sapindaceae
