Thanks for the info! Your picture/link that you sent along is wonderful. It is very close to mine, especially the pedals coloring, form, and white accents. It is the closest similarity that I have seen yet! But you are correct-- I will never know for sure! I sure it is some cross between this oncidium that you sent me and others that I have found. So I will just enjoy it for what it is-- a lovely NoID Oncidium. Thanks for taking the time. Greg.
