    Ce n'est pas une sp. nov., mais - par d?finition m?me - un nom de
remplacement (nom. nov.), car publi? pour un taxon ayant d?j? re?u un
nom (? un rang diff?rent), et que le type est le m?me. (Il s'agirait
d'une sp. nov. si le type ?tait diff?rent.)

>>  Dear Botanical TAXACOM members:
>>
>>  A debate has been raging among some botanists about whether a certain taxon
>>  was validly published, with some having very strong opinions that it was
>>  and others having equally strong opinions that it was not, so I thought I'd
>>  run it past TAXACOM members...
>>
>>  About a decade ago, a botanist published a new variety of plant, and the
>>  variety was validly and effectively published, with Latin diagnosis and
>>  type designated, so there is no problem with that name at that rank.
>>
>>  A few years later, a very prominent botanist decided that the taxon
>>  deserved specific rank.  He decided that the varietal epithet was not
>>  appropriate for the species, and coined a new epithet for the species,
>>  calling it a "nom. et stat. nov."  He made clear and direct reference to
>>  the varietal name and its publication, and the same type was used.  The new
>>  name was published effectively.
>>
>>  The debate has been over whether this was a valid way to publish the new
>>  species name.  Things would have been simple if the varietal epithet had
>>  simply been raised to the new rank, which then would have been a
>>"comb. nov."
>>
>>  Can I have opinions about the validity of the "nom. et stat. nov."?
>>
>>  (My own opinion is that it was validly published...)
>>
>>  Thanks.
