JEALOUS! I've come across this plant in the registry but couldn't find pics so I'm so grateful you shared this...and maybe a little bit envious...
I just picked up Roquebrune in bloom a couple months ago and am happy for it. It's still pretty new to me so mostly I just wanted to congratulate you on finding this plant. I have discovered with the Zygolum (Zygosepalum x Zygopetalum) I've had longest (only 7 months now) that they like a fair amount of water and rather bright light. I also just picked up Aganisia cyanea but still very much in the learning process with it so I'll have to check out that link OrchidsAreFun gave you.
Thanks for sharing, it's very beautiful.
