[Taxacom] Authorities for trinomials

Well, invalid names exist, in the same way that vernacular names exist and
geographical names and personal names. That is, the Code does recognize
their existence, in a general, peripheral way.

However, none of the rules in the Code apply to such names. The rules apply
only to validly published names. Only validly published names are part of
the "system of botanical nomenclature", thus are "scientific names" (in the
sense of the Preamble and Principles) or "names" (in the sense of Art 6.3).
This is quite fundamental to understanding the Code.

Best, Paul

there can be no such thing as an "invalid name" as this is a
contradictio-in-terminis. Certainly a name not validly published (an
"invalid name") cannot be conserved: it does not exist in the first place.
