Yes, confusion reigns, and it also dupes new growers who have no idea about the old McColley hybrids into maybe buying more than one plant because it has a different name.
That is why I don't think they should be merged in the data base. Prismacolor should be a separate listing.
I'm not sure when Cora McColley, who held the last parents on the original plants that her husband and Howard Miller made, died. I think she would have extended the patents if she was still alive.
I also don't think, by looking at the photos, that some of these PW plants even really LOOK like the old cultivars.
McColley and Miller hybridized a couple thousand or more plants during their work together at Gainesville and Apopka. Many of those hybrids were never carried forward through official registration process, much less patented.
Currently, to be a 'true' recognized name, either the species (in the case of a newly described-to- science plant) or the hybrid name must be registered through the International Aroid Society, which is the record holder for all that sort of stuff.
