Mystery Orchid

[JennS]

Hello! I have this mystery orchid that I have had for a little over a year. It was given to me by a lady at my previous job who had a huge greenhouse full. She would occasionally bring me a newbie when she repotted. Anyway, here is one she gave me that did not have a tag. It only had 2 flowers last year, but this year it has 4 on one shoot and another shoot developing. So far just the first flower is fully opened with a second that started opening today.

Anyway, the flower is really beautiful! I just have no idea what kind of orchid it is. I see a few different possibilities in it, but I would rather get everyone's opinions. The one picture with the envelope shows a small mailing envelope (the kind for mailing bills) to show how small the plant is. It is in a four inch pot with bark mix and some spag. Let the guessing games begin!
