Very nice but I think it is a sanderiana hybrid because it has spur at the back of the lip and the lip is not shovel shape and to few ridges on the lip. Also the tesselation on the dorsal sepals and petals is a sign that it has V. coerulea in its back ground. See the attached picture. If you look at the lip base of the two top flower's, you will see it does not have a spur also the shape of the lip is wide with 5 to 7 ridges on it. Hope this helps.
