Orchid taxonomy and naming authority?

[tropterrarium]

Thanks Lambelkip, quite instructive.

A new "Kew Rule" name, without Latin description or designation of new type, must be some sort of invalid name [nudum, illeg.]; that is also how previous authors have tagged it (who could be wrong, of course). Or is the situation similar as in nomen novum, where the nomen novum takes the description and type material of the old homonym, therefore becoming a homotypic = nomenclatural synonym? Any suggestion where these matters are dealt with in ICBN/ICN? (specific articles)

Interesting that only a valid name transfer leads to genus transfer credit. Any suggestion where these matters are dealt with in ICBN/ICN? (specific articles)

The older A name is also preoccupied by a senior homonym, so the correct name is neither A's nor B's, but a later synonym is considered the correct name today, so Kew does not show the genus transfer credit of the A's name. This was more re how to cite taxa properly in the historical context.
