| 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. |
