This is what I thought at first, but this proposed species is from Java, a long way from the Phillipines. So if it is a hybrid then it is either a man made one or a horticultural escapee.This one I don't get Valenzino. How is this any different than argus or even urbanianum? The staminode, which is the defining characteristic for most paph taxonomy (unless I am mistaken) appears to be identical with argus. I see urbanianum characteristics in the pouch shape and interior spotting. As well as similarities in the dorsal and the type of spotting that is shown on the petals.
With acmodontum, argus and urbanianum possibly overlapping geographically I tend to believe it is a combination of the above.
What are your thoughts on it? I know you have more extensive knowledge of them than I.
