I bought this dendrobium last weekend at the St. Louis Orchid show from an AOS/AM vendor but I can't remember what he told me it was. At first I thought it was a hercoglossum, but after viewing many images of them online I'm not so sure that assumption was correct. It has pinkish ends to the leaves with a somewhat white-ish center. There is a red dot in the middle of the flower on the lip similar to the hercoglossum ones I've seen, but the color is very different than any of the other hercoglossums. The hercoglossums I've seen are solid in color where these fade to white in the middle.
Sorry, my hand isn't the steadiest.
