A new variety, Bulbophyllum blaoense var. flavescences (B. sect. Cirrhopetaloides) discovered in southern Vietnam is described here. In addition, two species, B. caudatum and B. kwangtungense (B. sect. Desmosanthes) found in the northern part of the country are firstly recorded and documented for the flora of Vietnam. Morphological description and illustrations based on collected materials, data on phenology, distribution, and taxonomic notes are presented for newly recorded taxa. Lectotypes for B. bicolor and B. caudatum are proposed.
