Taxonomic remarks: —The holotype of Goodyera longirostrata ( Fig. 5G View FIGURE 5 ) contains a single plant with several leaves and two flowers (one had been cut and dissected). The leaves are thick-textured, broadly cuneate to rounded at base and flat in margins, with submarginal main lateral veins and 2–4 cm long stipes ( Fig. 5H View FIGURE 5 ); the flowers are relatively large, with sepals ca. 1.5 cm long and column plus rostellum ca. 9 mm long. All these characteristics indicate that this plant corresponds to the species commonly known as Goodyera seikoomontana (e.g., Barretto et al. 2011; Huang et al. 2012; Lin 2019), rather than a synonym of Eucosia (Goodyera) viridiflora as proposed by some authors (eg. Lin 2019; Pace 2020). The earlier published G. longirostrata should thus take priority against G. seikoomontana .
