In this study, we described and illustrated an unrecorded species from the Korean flora, Sciaphila nana Blume, which is included in the order Pandanales and the family Triuridaceae. This taxon was found at Mul Oreum in Namwon-eup, Seogwipo-si, Jeju Special Self-Governing Province for the first time in Korea. The order Pandanales can be distinguished from the order Liliales by the anomocytic or tetracytic stomata and syncarpous or apocarpous gynoecia of the Pandanales. The family Triuridaceae and the other four taxa in the Pandanales, Cyclanthaceae, Pandanaceae, Stemonaceae, and Velloziaceae, are easily distinguished because the Triuridaceae are microtrophic herbs with scaly leaves. S. nana has a subulate style with a glabrous apex, ovate to narrow ovate leaves and bracts, male perianth segments with a knob-like structure at the apex, and a dimorphic perianth. Therefore, it is easily distinguished from S. tenella, S. multiflora, S. secundiflora, S. thaidanica, S. ramosa, and S. arfakiana.
