Liparis hostifolia (Orchidaceae) on Minami-iwo-to Island in the Bonin (Ogasawara) Archipelago was rediscovered for the first time in 79 years during a field survey in 2017. Its identity was confirmed by morphological comparison and DNA extractions from herbarium specimens collected between 1914 and 1938. Results from the molecular phylogenetic analyses demonstrated that L. hostifolia belongs to the L. makinoana complex. In comparison with other members of the L. makinoana complex, the broadly ovate labellum, short dormancy period, and flowering from November to March are unique characteristics of L. hostifolia. Results from the molecular phylogenetic analyses also suggested that L. hostifolia has had a long-isolated history in the Bonin Archipelago and probably migrated from temperate East Asia.

Liparis koreojaponica Tsutsumi, T. Yukawa, N. S. Lee, C. S. Lee & M. Kato var. kiiensis Suetsugu & Tsutsumi (Orchidaceae) from Nara Prefecture, Japan is described as a new variety. It is similar to L. koreojaponica var. koreojaponica, but differs in spacing of the flowers (ca. 1.5 cm apart in the former vs. ca. 2 cm apart in L. koreojaponica var. koreojaponica), length ratio of rachis/inflorescence (1/3–1/2 vs. 1/4–1/3 in L. koreojaponica var. koreojaponica) and length of the labellum (13–15 mm long vs. 9–12 mm long in L. koreojaponica var. koreojaponica).

The taxonomy of Japanese Oberonia, particularly O. makinoi, has been confusing. Molecular analyses of Japanese Oberonia, including plants called “O. makinoi,” were performed. Phylogenetic trees deduced from the nuclear internal transcribed spacer (ITS) region, the plastid matK with trnK introns, and single-nucleotide polymorphisms (SNPs) data derived from MIG-seq show that “O. makinoi” collected from Shikoku and Kyushu is distinctive from the other species of Oberonia. The plants called “O. makinoi” differ from O. japonica in the leaf size and the flowering season. Furthermore, samples from the Ryukyus (Okinawa and Amami Islands) appear conspecific with, or closely related to “O. makinoi.” The taxonomic treatment of Japanese Oberonia requires further analyses using samples collected from central Japan and comparison to congeners in neighboring areas, particularly in Taiwan, where similar species are distributed.

Plants recognized as Liparis koreana (Nakai) Nakai ex W.T. Lee (Orchidaceae) in Japan and Korea is morphologically distinct from the type specimen of that species in the following points: flowers sparsely arranged (vs. closely arranged in the type); apex of anther cap mucronate (vs. beaked), lateral sepals twisting and enfolding the lip (vs. extending to the apex of the lip). Since these plants do not correspond with any known species, it is described as a new species, Liparis koreojaponica. The taxonomic status of L. koreana is reviewed.

A new species, Liparis purpureovittata (Orchidaceae), is described from central and northern Japan on the basis of both morphological and molecular characters. This species is distinguishable from the closely related Liparis kumokiri in the abruptly dilated labellum (vs. the gradually dilated labellum in L. kumokiri), the labellum recurved strongly in the middle (vs. the labellum strongly recurved in both the middle and distal part), and the column with rounded marginal wings (vs. angular marginal column wings).
