[Taxacom] Plant nomenclature query

[Stephen Thorpe]

There is actually a potential problem in the zoological code, whereby it is not clear exactly what is meant by "designation of a holotype" (though, of course, a unique holotype does not need to be designated as such). One scenario which I have seen happen is that a holotype is designated in the publication (from a series of specimens with identical data), but no specimen is labelled as the holotype, and there is no way to know which specimen was intended to be the holotype!

Hi Paul,

If designation of a holotype is part of validly publishing a new species,
and the holotype was never deposited, does that make the species a nomen
nudum?

Cheers,

Dick
