Annotated species list includes the valid name, synonyms, type, citations of relevant taxonomic regional publications, data on ecology, phenology and distribution, estimated IUCN Red List status, studied specimens, brief taxonomic notes, and illustrations for each recorded species. Lectotypes for two species, Liparis tenuis, and Dendrobium exsculptum are proposed. When the new data presented in this paper are included, the documented orchid flora of Vietnam reaches at least 1243 species. DO -10.6165/tai.2018.63.195
