EDIT

With the "new" rules from #3868 it is now easier to distinguish hybrids names and hybrid formulas.

E.g. Abies alba x beta is now parsable as hybrid formula for parents Abies alba and Abies beta.
Also Abies x alba is now parsable as clearly a hybrid name. Maybe some more issues are defined now.

In FM #6410 we have names like Nepenthes mirabilis x N. alata that should be parsable.

Searching for "Orchis" in Flora of Cyprus gives e.g.

• Orchis coriophora subsp. fragrans × sancta
• Orchis coriophora × sancta
• Orchis morio subsp. syriaca × papilionacea subsp. schirvanica
• Orchis × Serapias

We guess Orchis morio subsp. syriaca \u00D7 var. schirvanica is also a valid hybrid formula of a subspecies and a variety.

Open issues:

• hybrid formulas for >2 names (see also #3868)
• female/male formulas
• major/minor formulas (see also #3868)

The open issues will be handled in a new ticket to be opened when relevant
