I didn't see a tag for this while I was at the show, but when I got home and started looking through the photos afterward to pick the best one, I saw the sign in the background and wondered whether or not that sign was maybe supposed to go with this flower.
When I checked images on-line, that seemed plausible, so Paph. Jade Dragon (Paph. malipoense x Paph. fairrieanum) is my best guess. But maybe it's not.
