Hygrochilus and Sedirea are genera of orchids with only three species endemic to Asia. An analysis of ITS and five plastid regions combined using parsimony, maximum likelihood, and Bayesian methods obtains strong evidence that Sedirea is nested within and is synonymous with the genus Hygrochilus. We adopt a broadly defined Hygrochilus characterized by its possession of four pollinia, which is an explicit character state. A new combination, namely, Hygrochilus japonica, and a new species, namely, Hygrochilus tsii (Orchidaceae: Epidedroideae: Aeridinae), are established.
