I believe that the hybridizers of this daylily were Philip Adams ( I think that was his name) and his wife. They used to live in MS and had a garden there. I know that he is now deceased but don't know about his wife. I believe someone told me years ago that she had moved back to CA. As you likely know, it is the hybridizer who has to list the ploidy of his or her cultivars when they are registered. Sometimes mistakes are made by the hybridizer at the time of registration, or sometimes it is found out later that the registration data was incorrect. Sometimes conversions revert and offspring turn out to be diploid rather than tetraploid.. If the hybridizer is still alive ( and I don't know about the wife since this was a dual registration ) they MUST authorize any changes made to the database regarding their registrations. If it is determined that both are deceased then an attempt must be made to contact any heirs before changes are made to the data. This is NOT according to AHS rules. There are rules set in place by the ICNCP which AHS must follow in order to remain the registering body for the genus hemerocallis. We are hoping to soon form a committee to research such errors but it is not as simple as contacting the Registrar and stating that this data is wrong and expecting a change to be made because you think the data is incorrect. ANY corrections must first be thoroughly researched - looked up first in the paper checklists, check against other data and then contact the hybridizer or heirs before changes can be made. It is easy to say that " misinformation is being propogated in the database" but that is only a small part of the story!
