Plant Taxonomic Database Standards No. 3
*** I have not looked at this in detail, but a truly outrageous error immediately jumps out!, where it says "The full name of an intergeneric hybrid has in addition an "x" (lower case alphabetic x symbol) preceding the generic name as a generic hybrid marker. "
"The full name of a named interspecific hybrid or chimaera has in addition an "x" (lower case alphabetic x) or "+" plus sign) preceding the species epithet"
There is no conceivable ambiguity in "Art. H.1.1. Hybridity is indicated by the use of the multiplication sign × or by the addition of the prefix notho-¹ to the term denoting the rank of the taxon."
There never has been a "(lower case alphabetic x)" allowed, except where there is force majeure. "Rec. H.3A.2. If the multiplication sign is not available it should be approximated by a lower case letter x (not italicized)."
(BTW, there is no such thing as a "species epithet" in botany; it is a "specific epithet").
