Morphological, ecological, and molecular phylogenetic approaches reveal species boundaries and evolutionary history of Goodyeracrassifolia (Orchidaceae, Orchidoideae) and its closely related taxa.

ABSTRACT: Species delimitation within the genus Goodyera is challenging among closely related species, because of phenotypic plasticity, ecological variation, and hybridization that confound identification methods based solely on morphology. In this study, we investigated the identity of Goodyeracrassifolia H.-J.Suh, S.-W.Seo, S.-H.Oh & T.Yukawa, morphologically similar to Goodyeraschlechtendaliana Rchb.f. This recently described taxon has long been known in Japan as "Oh-miyama-uzura" or "Gakunan" and considered a natural hybrid of G.schlechtendaliana and G.similis Blume (= G.velutina Maxim. ex Regel). Because the natural hybrid between G.schlechtendaliana and G.similis was described as G.×tamnaensis N.S.Lee, K.S.Lee, S.H.Yeau & C.S.Lee
