To obtain a more definitive answer, I contacted Dr. Barry Rice with the following question:
There is a note in the CP Database for both 'Dente' and 'Dentate': "HC: the established name for the same cultivar is [Dionaea 'Dentate Traps' {B.Meyers-Rice}]". It also says 'Dentate Traps' was wild-collected, while 'Dente' and 'Dentate' are TC mutations. Does this mean that 'Dentate Traps' takes precedence over 'Dente' and 'Dentate', even though 'Dentate Traps' was published in CPN and registered in 2000, while 'Dente' and 'Dentate' were described and published in 1998 in Savage Garden (but not officially registered as cultivars?)? Are all three the same plant? There are also several other names floating around without official descriptions, such as "DentateTrap X11 form" and "Dentata".
Following is Barry's response (with permission):
"The official and correct name for all these cultivars is 'Dentate Traps'. I wrote the cultivar description to be broad enough to include them all under this nomenclature. The other plants may or may not be clonally identical."
"So the dentate traps term refers to any VFT of any origin that fits the broad description as I wrote it up. Mind you, if someone has a SPECIFIC clone they think is extra-special-double-plus-good, there is nothing stopping them from establishing this selection as a new cultivar. They just have to write up the distinguishing features that set it apart
from the crowd, etc etc."
"The key here is that the cultivar code and registration is a helpful tool, and not an obstruction or source of confusion."
"Incidentally, I would have rather used the name already in use, for my cultivar description; this would have established the cultivar name Dionaea 'Dentate'. However, the cultivar code says you cannot use purely adjectival names for cultivars (with a few exceptions) because it might be that the leaves, petals, stems, etc were "dentate". So I added "traps" to the name."
