I know this is a very old thread, but I thought I'd mention something of interest. I recently (a few months ago) bought a plant from Burnham Orchids, who told me it was a Phrag St. Ouen. It was in spike when it arrived, but sadly that was the final bloom of the spike. I didn't get around to photographing it, but it is only now that I say that to my dismay. Acting on a tip from a recent posting, I finally got around to repotting the specimen this afternoon. Only then did I examine the tag more carefully. The plant is from the EYOF originally. I had been told it was St. Ouen, and it sure looked like St. Ouen to my eye. But the tag says it is Phrag Plemont, with (St. Ouen) written in brackets. It was a pinker version of the one posted here, and sadly, with no photo to go by, I can't say for sure but I don't think it had those pronounced 'windows' to the pouch.
Given the state it was in, with it being a division already from a long stolon, and in that darned rockwool so probably overwatered... it looks like it will be at least a year before it recovers (I hope!) enough to bloom once more. Sorry for the lack of photo! There's a moral to this story somewhere, can't quite think what it might be...
