You can also find a place in a collection when you learn to use cultivar
epithets. It is this administrative reasoning that leads to the creation
of superfluous binomials. Replace yourself in the position of users of
cultivated plants who are often victim of the instability of scientific
plant names. My suggestion is that WHEN it can be avoided, don't create
more "latin" and ICBN-dependency than strictly necessary. In the case of
hybrids created in cultivation, for the purpose of being used in
commercial trade etc., DON'T create more "Latin" than necessary, so skip
the exercise of establishing nothospecific epithets but let taxonomists
of cultivated plants do the job in focussing on cultivar- and
cultivar-group nomenclature (ICNCP).

There will be a proposal by the Hybrid Committee in St. Lousi in which
typification of cultigenic hybrid genera is dealt with, using specimens
representing cultivars.
