That's a very nice flower. Can we get a photo of the whole plant?
I would not have guessed that was a Myrmecophila hybrid. The Guaritonia Why Not parent is easy to see though. Not technically a Cattleya, or course, but it certainly qualifies as a "Catt" in a general sense, if it boosts your ego to say you bloomed a Catt. I think most people would find this harder to bloom than a typical Cattleya hybrid.
