Abstract

Bulbophyllum trongquyetii is described as new for science from Vietnam. Detailed morphological description, illustration, data on distribution, and phenology are provided. Described species resembles B. nipondhii but differs in the bigger size of plant, longer inflorescence, and uniform yellow or reddish-orange flowers. It can be also compared with B. thaiorum and B. farreri but easily distinguished by the bigger size of plant and flowers, as well as smooth or sparsely papillose lateral sepals.
