Matucana ,
The bloom fell off shortly after this picture was taken. If it blooms again I will get some more photos.
All,
I sent photos to Dr. Williams, University of Florida , an orchid specialist. I hope to hear from him.
I also checked the Vasculiar Plant Atlas, University of Florida , which list plants by county and names. The plant I found is not in their Atlas.
