I see the difference. The landscape photo is particularly valuable from this standpoint. I hope you'll add the other photos to the database.
Responding to your earlier post, I'll use your number system.
1& 2 -- Correct spelling is crucial when you use the CoL. Unfortunately, it doesn't offer prompts when the spelling is incorrect.
3 -- I would urge you to stop using The Plant List. It hasn't been updated since 2012, and even that update was largely a copy-and-paste of earlier information, some of which was incorrect from the start. Some of the errors were corrected in 2012, including The Plant List's earlier insistence that Buddleia and Buddleja were two different genera.
The lack of updating has made some of the information obsolete, however. The Plant List still treats Spiraea x bumalda (S. albiflora x S. japonica) as an accepted name, for example, even though S. albiflora was reclassified as a synonym for S. japonica years ago. This means that the "hybrid" is now a cross of S. japonica x S. japonica. Absurd.
You are correct in your observation that the CoL does not recognize man-made hybrids. I can't explain the inclusion of E. cantabrigiense or the lack of information to suggest that E. setosa should be a hybrid taxon, but I have converted our E. x perralchicum and E. x warleyensis entries to cultivar entries because they do not belong in our database as hybrid taxa. We don't have an entry for E. x rubrum. We do have an entry for an E. alpinum cultivar named 'Rubrum.'
4 & 5 -- I've edited the 'Cupreum' entry to delete the species, and I've deleted the entire entry for 'Discolor' as an invalid name.
6 -- Thank you for the photos showing the difference between the two.
