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]
