Abstract:
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 GoodyerasubsectionReticulum. 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 Goodyerasubsect.Reticulum in China is also provided.
