CHALLENGE--Bulbophyllum-Wilbur-Chang-2022-09-21 *SITF determined this plant to be Bulbophyllum Jersey, not Bulbophyllum Wilbur Chang (Sep 2022); based on the form of the flower and differences in the lips as shown in comparison photos in the OW; Bussey's close-up photo of the lip of B. Jersey compared to Grobler's close-up photo of B. Wilbur Chang in the OW clearly show this plant to more closely match B. Jersey than B. Wilbur Chang; the wider falcate lateral sepals also more clearly match B. Jersey than B. Wilbur Chang.*

Awarded As: CHALLENGE- Bulbophyllum Wilbur Chang

This award was published and questioned by a student judge. In reviewing it, the student is correct that this flower does not exhibit the correct characteristics for Bulb. Wilbur Chang. My initial impression was Bulbophyllum Jersey. I contacted the owner of the plant for additional information. This was purchased at an auction with a tag labeling it as Wilbur Chang. The exhibitor contacted Bill Thoms, who also agreed that they flower distinctly matches Bulb. Jersey. Specifically the form and stance of the flower and the shape and coloration of the lip. The first photo is the award shot and the additional photos were supplied by the exhibitor.
