Well, I didn't actually buy this, it came to me in trade with a friend who has 11 acres and keeps horses up north of Orlando.
It is a native quite common in the southeastern states, Epi.Magnoliae commonly known as the "Green-fly orchid". Flowers are tiny, about 3/4in across at most, and the leaves are about 2in. long. They are on hunks of bark growing with resurrection ferns, and my friend found them on a fallen branch on her property. The flowers are greenish white and fragrant at night.
