All I can say is your photo matches my plant exactly, right down to the colors, the green on the edges of the petals, the deep burgandy/maroon color, the subtle striping on the lip. The link to Gabriella's beautiful orchids photo's as a beautiful blue/purple on the lip but otherwise identical. I'm no expert and I only reported what was on the plant tag and they are known to be wrong so I'll wait for the experts to weigh in but it wouldn't surprise me to learn that it's a cross of the Zygopetalum mackaii.
