Abstract
A new orchid species, Bulbophyllum pingnanense, is described and illustrated from Fujian, China. It is similar to Bulbophyllum brevipedunculatum and Bulbophyllum albociliatum in vegetative and floral morphology, but it can be distinguished from Bulbophyllum brevipedunculatum by having a longer dorsal sepal with longer white ciliate on margin, longer and lanceolate lateral sepals, and a glabrous lip. It can be distinguished from Bulbophyllum albociliatum by having a shorter inflorescence, and a longer dorsal sepal.
