Abstract
Three taxa, Bulbophyllum cariniflorum var. orlovii (sect. Pleiophyllum), B. sonii (sect. Anisopetalon) and B. ustulata (sect. Brachystachya) are described as new for science. All of these novelties are local endemics of Vietnam. Additionally, four species, B. flavescens (sect. Aphanobulbon), B. ovatum (sect. Desmosanthes), B. physocoryphum (sect. Macrocaulia) and B. wendlandianum (sect. Cirrhopetalum) are recorded for the flora of Vietnam for the first time. These species are endemic of the Indochinese Peninsula in a broad sense, except for B. flavescens having wide distribution in western Malesia. Data on ecology, phenology, distribution, brief relevant taxonomic notes, as well as colour photographs and line drawings of the type and voucher specimens are provided for all reported taxa. Lectotypification is provided for B. wendlandianum.
