Then it should be listed as another cultivar name. I'll edit it and show you the result.
Hen and Chicks (Sempervivum 'Euphemia')
As for the others, here's a working list of Sempervivum species. Only the ones in bold-face green are accepted names. Others are synonyms or unresolved.

Your list of species should include only the accepted names. The synonyms should be added to the appropriate accepted names and the entries for the synonyms should be deleted, but make sure you move all photos, comments, and other info to the entry for the accepted name before deleting them. I think our present policy is to ignore the unresolved names until we hear an update.
Something unique seems to be happening in the Sempervivum database. Arachnoides is not a species name, for example, and what's the reason for all of the different S. arachnoideum entries? What's the significance of f/Abruzzi and f/Sion, for example?
You also have some obvious duplicates in there: S. arachnoideum L. subsp. tomentosum and S. Arachnoideum subsp tomentosum, for instance. Neither is correct. The correct form would be S. arachnoideum subsp. tomentosum (leave out the "L" and include a period after "subsp").
