It's hard to tell. The psuedobulbs look a little like my encyclias but the leaves are wider than the encyclias I've seen. Hopefully someone will be able to ID it.
No idea first I thought Anacheilum (Encyclia) cochleata but it's not then maybe Dendrobium or a a cross with a true Encyclia. Better pictures might help to be more precise.
I agree with Robs that it is probably in the Prosthechea group which were previously classified as Encyclia. Cochleata is a Prosthechea not Anacheilum.
The very tall thin bulb is typical of prismatocarpa or more likely a hybrid of it.
wow thanks, I'll have to look all that up...
I'll wait till it flowers and prob get a better idea from that.
Hope it flowers soon.
Thanks for every ones feedback.
