I had never heard of this either. I know it will be impossible to get an exact name for it, but it's not less beautiful. I wasn't very in for Paphios, but since I managed to rebloom another NoId I have, I do like them. Beside these NoId's I also have a Paphiopedilum dianthum and a spicerianum that haven't bloomed yet. I hope they'll bloom for the first time this year when their season comes.
It looks like a complex Paph. to me. Likely has some insigne and/or spicerianum. Both of those species hold their dorsal in a similar manner. I would also guess it has some Spotglen, and Winston Churchill.
