This is an unusual bulbophyllum that I received as a door prize at one of the Orchid Society banquets. The plant came from Wilbur Chang's collection. The central core of the flower has a diameter of 3/4-inch. The diameter of the imaginary circle formed by the tips of the petals is about 3 inches. The plant is grown in a 3-inch square plastic pot with New Zealand sphagnum as the media.
