I am no taxonomist, but on what authority can people "play" around with
nomenclature?

Peter

Anyone can play around with taxonomy provided they can get published. In
extremis you can self-publish, and post photocopies to a few herbaria.

Nomenclature is subject to the rules of the ICBN (for "wild" plants),
ICNCP (for cultivated plants), ICZN (for animals), etc.
