Yes, Gigi it's a brassavola/cattleya cross, I think. Let me check the tag . . . Yes, it says Bc. Punakea [Maikai X Lulu].
I'm nuts about the Lemon Chiffon, too. Just love anything pale yellow! It looks like a cross that might have come from Krull-Smith? We saw a lot of yellow catts with red splashes on the lips like that in their greenhouses.
