Bulbophyllum yunxiaoense sp. nov. (Orchidaceae: Epidendroideae: Malaxideae) from Fujian, China: Morphological and molecular analyses

We have described and illustrated a new species, Bulbophyllum yunxiaoense (Malaxideae, Epidendroideae, Orchidaceae), from Fujian Province in southeast China. The size and overall floral morphology of the new species are similar to those of Bulbophyllum pingtungense , a species endemic to Taiwan Island on the southeast coast of China and its closest relative according to a cladistic analysis of nuclear (ITS) and plastid ( matK , trnL-F , and atpI-atpH ) DNA sequences. However, B. yunxiaoense is distinguishable from B. pingtungense by flower colour, shorter scape, and longer lateral sepal.
