Fear not, it isn't as bad as it sounded. Stephen just misread his reference. While they do consider any sexual
cross a hybrid, they have a set of rules to govern how that is designated. What you and I would call cultivars,
they've invented new jargon for. But interspecies hybrids are still designated by the ol' "X" between the species
names, and inter generic by an "X" before the grex name.
It has, it seems, if this set of rules is to be accepted, taken ALL meaning out of the commonly used term hybrid.
They are trying to make rules for "Nothotaxa" (the silly new genus names people give to intergeneric hybrids) and I
suppose that's a good thing?
