  • A taxonomic study of Habenaria in Korea was carried out based on the extensive examinations of floral morphologies and distribution. As the results, we classified the genus in Korea into the following 5 species; H. linearifolia Maxim., H. cruciformis Ohwi, H. radiata Splengl., H. chejuensis Y.N. Lee & K.S. Lee and H. flagellifera Makino. H. cruciformis is recognized as a distinct species distinguished from H. linearifolia, H. sagittifera Rchb. f. and H. schindleri Schltr., and we clarified its morphological differences from the species. H. linearifolia f. integrilova Ohwi which has been seperated by shape of lateral lobe of lip was merged into f. linearifolia oin this study. Furthermore we investigated the distribution of Habenaria in Korea based on the herbarium specimens and field surveys. The result shows that H. radiata is rare in the middle part of the Korean Peninsula and H. chejuensis and H. flagellifera are restricted in Jeju Island, so the conservation on the habitats of these species is required.

  • An unrecorded Orchid species, Habenaria dentata (Sw.) Schltr. (Orchidaceae), was recognized in Gahoe-myeon and Ssangchaek-myeon, Hapcheon-gun, Gyeongsangnam-do, South Korea. H. dentata is closely related to H. radiata (Thunb.) Spreng., it can distinguished by sepal white and larger than petals, and serrated margins of the labellum. A new Korean name, 'Keun-hae-o-ra-bi-nan-cho', was given based on its taller stem and more flowers (at least with three) in comparison to H. radiata (Thunb.) Spreng. We provide here its redescription, illustrations, photographs, and a key to its closely related taxa.

  • This study was carried out to investigate the factors affecting seed germination of Korean native orchids, such as Habenaria radiata, Bletilla striate and Cypripedium macranthum. In general, seeds of H. radiata was effectively germinated on solid medium and the highest germination (29.6%) was achieved on Hyponex solid medium. But shoot growth was better in MS liquid medium containing $100mL\;L^{-1}$ coconut water (MSC medium). Seed germination of B. striata was effectively induced on MS solid medium. However, no seed germination was observed in all liguid medium tested. Seed germination experiments of C. macranthum were performed using 6 kinds of media and seeds harvested 90 days after cross- and self-pollination. Cross-pollinated seeds were germinated on all the media with the best germination ratio of 4.45% on MSC medium. But no germination was observed from self-pollinated seeds.

  • The experiment was tried to identify culture media which was suitable for seed germination and seedling growth of wild orchids, Calanthe discolor and Habenaria radiata. When seeds of Calanthe discolor, which was treated with ultrasonics for 30 minutes, were sowed in Murashige and SKoog(MS) medium, germination was much more promoted than other treatments. Seedling of C. discolor grew more rapidly in 3g/L Hyponex and 2g/L tryptone(H$_3$T$_2$) medium and 3g/L Hyponex and 2g/L peptone(H$_3$P$_2$) medium, especially in H$_3$P$_4$ medium among those media, pseudobulb became more corpulent. Habenaria radiata, whose tubers were obtained from seedlings, were sprouted more vigorously in 3g/L Hyponex and 1g/L peptone(H$_3$P$_1$) medium and 1g/L Hyponex and 2g/L peptone(H$_1$P$_2$) medium; but multiplication of tubers, growth of daughter tubers and its corpulence were well established in 1g/L Hyponex and 2g/L peptone(H$_1$P$_2$) medium.

  • The distribution on 88 taxa of wild orchids in the Korean Peninsula was investigated by the examinations of specimens and the distribution maps were presented. The species numbers distributed at each eight floral regions in the Korean Peninsula are as the followings; Gapsan Province 27 taxa, Gwanbuk 21, Gwanseo 13, Middle 37, South 39, Southern-coast 33, Jeju 64 and Ulleung 19. Most species (72.7%) of Korean wild orchids are found in the Jeju Island. Eighteen taxa of them are restricted to the island in the Korean Peninsula. Among Korean species, 30 taxa grow at evergreen broad-leaved forests, and 16 are northern elements distributed at high mountains or northern part. In terms of distribution, the Korean wild orchid species are classified into IUCN Red List Categories by a modified criterion for Korean plants. No orchid species included EX or EW categories is found in the Korean Peninsula. Ten species are designated to be in CR category; Cymbidium kanran, C. lancifolium, C. ensifolium, Cypripedium japonicum, Cyrtosia septentrionalis, Dendrobium moniliforme, Habenaria chejuensis, H. radiata, Neofinetia falcata and Sedirea japonica, of which C. ensifolium and H. chejuensis are regarded as CR species for the first time. On the other hand, 22 taxa are classified into EN category, and the following nine taxa are newly proposed to be EN species; Gastrochilus japonicum, G. fuscopunctatus, Gastrodia verrucosa, Habenaria flagellifera, Herminium lanceum var. longicrure, Chamaegastrodia sikokiana, Lecanorchis kiusiana, Neottia hypocastanoptica and Tipularia japonica.

  • This study was conducted to investigate the vascular flora of two outstanding forest wetlands(OFW) in Goheung-gun, Jeollanam-do, and to prepare an efficient management plan for forest wetlands through comparison with previous studies. Fieldwork was conducted seasonally from May to October 2023, The flora in the two OFW located in Goheung-gun, Jeollanam-do, consisted of 117 taxa such as 55 families, 92 genera, 108 species, 7 variants, 1 variety and 1 hybrid. The endemic plants were 4 taxa and rare plants were 7 taxa. Floristic target plants were V class 2 taxa, IV class 6 taxa, III class 8 taxa, II class 4 taxa and Iclass 21 taxa. Climate change adaptation plants were 10 taxa and naturalized plants was 1 taxa. Obligate wetland plants were 16 taxa, Facultative wetland plants 10 taxa and Facultative plant 4 taxa. OFW functioning a typical wetland ecosystem in Goheung-gun had been providing habitats for a variety of rare plants, such as the Habenaria radiata and Drosera rotundifolia. But those ecosystems would be suffering a critical disturbance such as human interference, the invasion of naturalized plants, and change of wetland function through landization for a short future. Therefore we suggest those OFWs should be designated as a Forest Genetic Resource Reserve in order to keep the ecosystems permanently and to manage them more soundly and efficiently.
