Juli,
I bought Tet Ed Murray in the late 90's and it was very commonly sold back then - I don't think the tet version cost much more than the dip back then - not sure when the discussion about it was held, probably earlier than that since this cultivar has been around a long time! I still grow it.
Regarding the Carpenter cultivar, since the printed checklist is the official record of registration and the hybridizer is still alive, the only way for the incorrect data to be changed is for the hybridizer to request a change in the data!
It is easy to assume that mistakes are always transcribed into the database and that is not always the case. Any of you who register daylilies know that once you receive registration confirmation, you receive a copy of the data submitted that you should check all submitted data very carefully. Any errors you find on the registration sheet should be sent to the registrar immediately so that corrections can be made then. I wish that everyone would check the proof sheets carefully, but know that regrettably this doesn't always happen. I have personally seen such instances recently when proofing the 2012 checklist before it was published.
