You will never know the answer to your question, sorry.
Unless a species plant is from a verified collection site it is impossible (read that as: IMPOSSIBLE) to ever know the truth.
Too many orchid growers and exporters are just too reckless these days of tissue culture labs and creative ideas.

Getting back to the origins of this thread..... Lance; when I suggested the MSBGOIC, I was keeping in mind that this forum is populated by and predominately run for amateur hobbyists.....simple enthusiasts, not scientists. I was keeping the context of the question in mind when I posted my reply.
Technically, I believe your comment above to be true; but, in the real world, the one we amateur enthusiasts live in, that would mean all plants that cannot be verifiably traced all the way back to the original collection from the wild, cannot be considered to be a species. So, all of our species Paphs in our collections shouldn't be labeled as such. I think that's just not practical or a useful possition to take, in the context of this forum. Yes, it's technically true; but, it's completely unworkable for the masses of all us non-purists.....not to mention the nurseries like Orchids Limited and Orchid Inn and Piping Rock, etc., who supply us with our "species" plants.
In the interest of hopefully preventing yet another hybrid plant being "identified" and given the status of species, based on little more than a "best guess", by an amateur hobbyist and his Internet friends, I just wanted to give Roy a better alternative to coming up with a correct, probable identification.
I recognise that coming up with an identity for his plant is a probability thing....not 100% accurate; but, having his plant identified as "primulinum", or, a "primulinum hybrid" by someone far knowledgeable than any of us, has got to be better and more desireable than him deciding by himself.
