Abstract
A new species of Goodyera (Orchidaceae) from Tibet, China, G. medogensis, is described and illustrated here. This new species is most morphologically similar to G. hemsleyana, but differs by the thick grid lines of reticulations with blurred margin on adaxial surface of leaf blades, inflorescence with more flowers, petals obliquely obovate-rhombic, labellum yellow or yellowish, without lamella on blade, and floral bracts, sepals and ovary with non-glandular trichomes. Molecular phylogenetic study also supports that G. medogensis is a new species and belongs to G. subsection Reticulum.
