I'll start by addressing the simplest matter. You say that the CoL does not recognize E. omeiense. It does recognize it as an accepted hybrid taxon and we have had an entry for Epimedium x omeiense since the first day of our database (9/16/2011).

Epimedium x omeiense
It also recognizes E. sasakii as a hybrid taxon. Our own entry did not have the required "x," so I have edited it to add the "x."

Now, on to the more complicated matters. We use the Catalogue of Life because it is the most comprehensive and most current (updated just yesterday, actually, and listing November 2017 as the latest taxonomic scrutiny of the epimedium entries) taxonomic source available to us.
It still does not list E. versicolor as an accepted hybrid taxon. It could do this in the future, especially now that Kew has become one of its main sources. I'm going to edit our cultivar entries for Sulphureum and Neosulphureum to remove the species name, but I will list it in the also-sold-as field. That way, it wil be easy to find the E. x versicolor cultivars when and if the CoL lists it as an accepted hybrid taxon.
I need your help with something else. We have two other cultivars listing E. versicolor as a synonym: Discolor and Cupreum.
Fairy Wings (Epimedium 'Cupreum') Should I edit these in the same way?
I'll also move HemNorth's two photos to the 'Sulphureum' entry. Is Calif_Sue's 'Neosulphureum' photo in the right place?
