My understanding is that "triticale" is X Triticosecale rimpaui Wittm.
[Triticum aestivum x Secale cereale], the genus having been described by
Wittm. as well.

I believe that each proven plant hybrid deserves a binomial that follows
precisely the botanical rules of nomenclature.  Many have yet to be named.
Orchidologists seem to have tahen the lead on naming intergeneric hybrids,
but few have taken it to the species level, choosing cultivar names instead.

We need a pigeonhole for these in our collections! Every specimen should
have its place, looked at from a utilitarian standpoint.
