Resurrection and Lectotypification of Taeniophyllum aphyllum (Orchidaceae)

Abstract

The taxonomic status of Taeniophyllum aphyllum (Makino) Makino, described from Kochi, Japan, is reevaluated. It has often been treated as a synonym of T. glandulosum Blume from Java, Indonesia, but is distinguishable from T. glandulosum by the pubescence of the inflorescence rachis, the arrangement of the flowers, inflorescence length, and shape of the fully developed fruit. It is therefore proposed that T. aphyllum is recognized as a distinct species. A lectotype for T. aphyllum is also proposed.
