From the exhibitor:
I obtained this plant at the 19th WOC in Miami. I don't know who the vendor was, but I'm sure the plant was imported.
The flowers are ethereal, and might last through the day if conditions are cloudy and cool. Otherwise, they wilt after 6-8 hours.
There was a short profile of this species in Orchid Digest Vol. 72-3.
