“…6) showed 2n = 60. In line with the results obtained in this study, Oh et al (2022) reported 2n = 60 for a Korean G. crassifolia individual. Intriguingly, Sera (1990) reported 2n = 60 in five "G. schlechtendaliana" plants from four localities, while reporting 2n = 30 for most G. schlechtendaliana individuals (60 plants from 22 localities collected throughout Japan).…”

“…The lateral column appendages are consistently absent in the closely related taxa. Since the lateral appendages are themselves column-like, they are likely to be enlarged staminodes (Oh et al 2022). Notably, the lateral appendages of the column differ significantly in size among populations, and in terms of their position on the inflorescence, being often conspicuous in the basal flowers and inconspicuous (or rarely absent) in the apical flowers.…”

“…Further detailed comparison of morphological characters among G. crassifolia, G. schlechtendaliana and G. ×tamnaensis is given in Table 1. Additional descriptions and illustrations of G. crassifolia, G. schlechtendaliana, G. ×tamnaensis, and G. similis are available in Lee et al (2010Lee et al ( , 2012, , Suetsugu et al (2021b), and Oh et al (2022).…”

“…Ecological data based on breeding systems can further clarify whether morphologically distinct populations should be considered separate, reproductively isolated species (Kallunki 1981;Coyne and Orr 2004;Botes et al 2020). In the present study, we investigated the identity of Goodyera crassifolia H.-J.Suh, S.-W.Seo, S.-H. Oh & T.Yukawa-recently described in Korea and Japan (Oh et al 2022)-using a multifaceted approach. Goodyera crassifolia is morphologically the most similar to G. schlechtendaliana Rchb.f.…”

“…Given that G. ×tamnaensis was described before G. crassifolia, it is possible that G. crassifolia is a junior synonym of G. ×tamnaensis. However, the report by Oh et al (2022) did not include a comparison between G. crassifolia and G. ×tamnaensis.…”

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 Goodyera crassifolia H.-J.Suh, S.-W.Seo, S.-H.Oh & T.Yukawa, morphologically similar to Goodyera schlechtendaliana 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 before the description of G. crassifolia, the latter might be a synonym of G. × tamnaensis. Consequently, we investigated species boundaries and evolutionary history of G. crassifolia and its closely related taxa based on multifaceted evidence. Consequently, morphological examination enabled us to distinguish G. crassifolia from other closely related species owing to the following characteristics: coriaceous leaf texture, laxly flowered inflorescence, long pedicellate ovary, large and weakly opened flowers, and column with lateral appendages. Ecological investigation indicates that G. crassifolia (2n = 60) is agamospermous, requiring neither pollinators nor autonomous self-pollination for fruit set, whereas G. schlechtendaliana (2n = 30) is neither autogamous nor agamospermous but is obligately pollinator-dependent. MIG-seq-based phylogenetic analysis provided no evidence of recent hybridization between G. crassifolia and its close congeners. Thus, molecular phylogeny reconstructed from MIG-seq data together with morphological, cytological, and ecological analyses support the separation of G. crassifolia as an independent species.

The delimitation of species within the genus Spiranthes (Orchidaceae) is problematic due to the intricate interplay of phenotypic plasticity, ecological variation, and hybridization, making identification that relies solely on morphology inadequate. In light of morphological and phylogenetic data, we have described a self-pollinating species, S. minamitaniana within the Spiranthes sinensis species complex. Spiranthes minamitaniana shares several morphological features with S. hachijoensis, such as glabrous inflorescence rachis, ovaries, and sepals, a degenerated rostellum, pollinia without a viscidium, and papillate lip basal callosities. However, it can be distinguished by several morphological traits, including semicircular, weakly-or non-3-lobed stigma, and more conspicuous anther cap. Although S. minamitaniana is morphologically most similar to S. hachijoensis, phylogenetic analysis strongly suggested that S. minamitaniana has independently acquired a selfing reproductive mode and constitutes a separate genetic cluster from it. As such, this taxon is morphologically and phylogenetically distinct from other closely related species. Consequently, this taxon is morphologically and phylogenetically distinct from other closely related species.
