[Taxacom] Name the hybrids in vascular plants

[Paul van Rijckevorsel]

There are (at least) four options:
1) describe as a species (like Triticum aestivum,
    Art H.3 Ex. 3)
2) describe as a nothospecies (like Mentha ×smithiana,
    Art H.3 Ex. 1)
3) describe by a hybrid formula (like Agrostis stolonifera L.
    × Polypogon monspeliensis (L.) Desf., Art H.2 Ex. 1).
    See also Rec. H.10B.1, at least its spirit.
4) describe as a cultivar

The choice between these is a matter of degree, depending
on how important the newly described taxon is perceived
to be. Obviously, a status as a species (non-hybrid) is only
called for in case of a long-established taxon.

The general tendency is to increasingly treat hybrids as
cultivars, with many former species that were well known
horticulturally having been renamed to become cultivars.
