I found the usual tetraspis C#1, and also Phal. speciosa red x blue which looks like the one is the photo you shared. Now to decide which of the 2 to buy...
I don't have a photo of Phal. tetraspis with multiple flowers, but here's Phal. speciosa. I think there's 2 or 3 spikes, 2 or 3 flowers on each spike. All different.
