Abstract
Herminium (Orchidaceae, Orchidoideae) is a medium-sized genus widespread in the northern hemisphere, with a clear centre of diversity in the Himalayas. We present a comprehensive taxonomic revision of Herminium based on field observations and morphological studies, for which we examined about 2500 specimens. We recognize 49 species grouped into six formal sections, including one new speciesHerminium tibeticum, from Tibet. We provide an identification key to the species, descriptions of the species, notes on ecology and distribution, and complete nomenclature for each species, including typifications. We here designate lectotypes for five species and reduce four taxa to synonymy.

Keywords: Herminium tibeticum, key, morphology, synonyms, taxonomy
