Summary: A new species of Goodyera (Orchidaceae) from Tibet, China, G. medogensis , is described and illustrated here. Molecular phylogenetic results based on one nuclear (ITS) and two plastid markers (matK and trnL-F ) support the recognition of G. medogensis as a new species in Goodyera subsection Reticulum. Morphologically, the novelty is most similar to G. biflora , G. vittata and especially to G. hemsleyana , but differs by the thick grid lines of the reticulations with a diffused margin on the adaxial surface of the leaf blades, the inflorescence with more flowers, the obliquely obovate-rhombic petals, the yellow or yellowish labellum without a lamella on the blade, and the shorter trichomes on the floral bracts, sepals and ovary. Finally, a key to the species of Goodyera subsect. Reticulum in China is also provided. Keywords: Cranichideae , Jewel orchid, morphology, new species, Orchidoideae , phylogeny
