That's a very nice one of the form that was sold as bodegomii some years ago ( 10-15?). In the trade there were praestans ( with green leaves), praestans red leaves ( with the leaves nearly completely red burgundy), and the bodegomii with some red at the base and a big pouch ( like yours).
I will take a pic of wilhelminiae, it exists, and is about the size of paph helenae when it blooms. As for glanduliferum, they arsupposed to come from Obi Islands only, may be a geographic variant or a completely new species. No one ever went again to that place so far, but it is quite far from the PNG islands where the "praestans" are found, so we cannot rule out that it is really a distinct species. The painting shows a white ovary if I remember correctly, found tody only in gigantifolum and sanderianum for the multiflols ( and supposedly as well in elliottianum...). The other problem ons encounters with taxonomists is that some of them are so far from reality. Phil Cribb was sure for several years that paph armeniacum was a variety of delenatii... And I heard that actually some hangianum appeared in the early 90's, that were deemed by a very famous taxonomists to be an abnormal form of emersonii. For me, as long as no one is willing to go to Obi, I will be sure that glanduliferum is a lost species. Blume, when he provided localities for many of his plants, was perfectly accurate. So I am sure that there is something on Obi island, remains to see if it is a praestans or something else...
