Here are some pictures of the Cat that I sun burned last year. Not burned as bad as yours but the Noid Cat seems no worse for the damage. It has 8 large blossoms on it right now and is very fragrant.
Just an anecdotal story: I purchased several (like 8) seedlings, mounted, from a supplier in southern Florida last year. I asked them about lighting. They said "full sun" (that's a quote!) So when we continued down to the Keys, I placed them in a south-facing window in the condo and was surprized at how fast they turned purple! The last black leaf just fell off the last one to get totally fried. This was just two days under way to much light. It happens. The plants are doing much better now. Yours will also, I predict. Don't sweat it. Just move on from here. That's the end of my story!
Thanks Ross, Bill, and all. I did cut the leaves, and am watching it close. Now perhaps I shouldn't have cut them, but I was afraid it would affect more of the leaves.
Your pics, Bill, gives me much needed hope. Thanks. I have 5 spikes on that plant. All that is left is to
Good luck. I hope it works out for you. Just be patient. It will be a couple years before it all looks normal again. One other thought, and you won't like it. If I were you I would watch the Cattleyea very close and if it starts to look too stressed I would cut the flower spikes off. It takes a lot of energy from the plant to support those spikes. I've done it in the past to save a plant. It killed me to do it but I wanted the orchid to survive. Keep them for now but if the Cattleyea takes a turn for the worst, cut them off.
