I did a quick google search and the only thing I could find was your original post lol.
A broader search suggests that it could actually be Oerstedella caligaria. Its an interesting plant from what I have seen on the net so far.
The canes should be pendulous like a Den. anosmum and a cluster of flowers emerge from the tip of the cane, like an Epi. radicans.
The flowers also resemble Epi. radicans but they are purple and the lips appear to be split up into several segments.
The more I read about it, the more I want one lol.
It appears to be very rare in the market, or just a new introduction that is just starting
to make its presence known.
It has got to be the most flamboyant lip structure I have even seen.
