Well, aside from looking like a Dendrobium, I'm sorry I can't help. It reminds me of Den. schuetzii or a hybrid thereof. http://www.orchidspecies.com/denschutezii.htm Hope someone recognizes it because I want one! It's gorgeous.
How about this one? It was given to me unlabeled about ten years ago as a small plant. The leaves reach three feet, with a spread of four feet. There are three spikes on the plant and a total of 30 individual blooms.
