The tag says "Paph chamberlainianum v liemianum". Somehow I wonder if this isn't a primary cross between the two and not a "variation". And if it is a cross, that would make it Paph Salvador Dali. This flowers faithfully for me and as you can see there will be more flowers later....
I bought a dali yesterday and it does look a lot like this one, although the labellum (that's the lip, right?) has a slightly more spotted character than the one in this photo. The grower told me that he's able to keep these flowering all year as they're sequential bloomers.
