They are smaller growing cattleya-alliance plants. The name is Diacrium. Most of them are compact growers. Take care of them like catts.

So...I bought a mystery orchid the other day that was labled as a catt. but I knew it was wrong...I assumed it to be a dendrobium but I went back to the store and saw another one that HAD an id stake (grrr...) and as it turns out, it's a diaca.! I've never even heard of that species and managed to pick one up haha Anyway, she's a cute little thing...pretty compact with two inch white, purple spotted flowers. Any information I can get on her? Will she stay small? What are her cultural requirments? I couldn't find much...
Diaca = Diacattleya = Cattleya x Diacrium
Diacrium = Caularthron
As Clint said it's part of the Cattleya alliance so you won't have any problems if you had Catts before. However, their light requirement is usually a bit lower than the Catts.
Thank you Clint and Phyrex! Ugh I don't know what I did...it's lead pbulb is becoming soft with fine lines in it...it was very firm and smooth two days ago. I just watered and fertilized it this morning. I didn't notice this until after I watered it...it was pretty dry before, so it seemed ok. I have a long way to go to take care of these plants lol
We grow ours with the mini-cats. They get a bit lower light than standard cattleyas. Keep an eye on the pbulb and be sure to remove it if it becomes mushy and starts rotting. Hopefully it is nothing to worry over.
