Abstract

This paper summarizes results of joint efforts of professional botanists and orchid enthusiasts on studies of Vietnamese native orchids during years 2013–2016. It provides new original data about the discovery of 1 genus (Grammatophyllum Blume) and 29 orchid species new for the flora of Vietnam. Valid name, main synonyms, data on type, ecology, phenology, estimated IUCN Red List status, distribution, studied specimens, as well as brief taxonomic and biological notes are provided for each species and varieties. Eight species (Bidupia khangii, Bulbophyllum striatulum, B. tipula, Cleisostoma dorsisacculatum, Cymbidium repens, Dendrobium congianum, Flickingeria xanthocheila, Podochilus rotundipetala) and two varieties (Phreatia densiflora var. vietnamensis, P. formosana var. continentalis) are described as new for science. One combination (Bulbophyllum bicolor var. funingense) is proposed. An illustrated annotated list of all studied species and varieties is arranged in alphabetical order. Including present data, the known orchid flora of Vietnam comprises currently at least 1210 documented species from 172 genera.
