The important bit for this discussion is that we do need extra elements to correctly discover, list and render names. These include (though incomplete): a named hybrid indicator; [...]
*** A single hybrid indicator will not do it; commonly there are three levels at which hybridity may be registered: 1) genus 2) species 3) infraspecific taxon
As in Mentha ×piperita subsp. ×pyramidalis (Rec. H.11 Ex. 3), in contrast with Mentha ×piperita f. hirsuta (Rec. H.12 Ex. 1),
[in addition there is also the subdivision of a genus which may be a hybrid, but this will hardly ever be included in the name of a lower ranking taxon]
