I explained our policy on synonyms higher up in this thread when Calif_Sue asked the question.
zuzu said:No, Sue. There's no need to add any more synonyms. We add synonyms only when we have an entry for the obsolete name that has to be deleted, or when someone proposes a new plant that turns out to be only a synonym for an existing entry. In other words, we add only the names that people might be seeking.
Unless our Kwanzo entry is renamed as a species, there is no reason to add H. fulva var. kwanso to the H. fulva var. fulva entry. We never had a Hemerocalis fulva var. kwanso entry to delete, so we don't have to add it as an explanation for someone looking for the deleted entry.
If the cultivar names of some daylilies turn out to be names that have been given mistakenly to species dayliies, the cultivar entries should be merged with the appropriate species entries, and the "cultivar" names should be added to those species entries as also-sold-as names.
It's great that you found the photo and the correct name. I'll leave the move to Calif_Sue or bamira.
