I have only ever seen the Swan Island introduced "Enchantress", which are the photos shown in this database. My guess is that the other entries in the master list are long gone (stock breaks down, crappy tuber maker, something similar that was newer and better was grown instead). My guess is that if they are still around, well they are so minimally circulated that no one ever sees them.
You are spot on, though, the listing details for Enchantress are incorrect for the variety that is currently being grown and shown here.
