Two New Bulbophyllum (Orchidaceae) Species in Taiwan:B. brevipedunculatum and B. ciliisepalum

Bulbophyllum (Orchidaceae) is the largest orchid genus in Taiwan. It is taxonomically problematic due to difficulty of field collection and morphological similarities between some species. In this study, we recognized two new Bulbophyllum species, B. brevipedunculatum and B. ciliisepalum, from eastern and central Taiwan. Descriptions, illustrations, and comparisons among related species were also presented.
