External morphology focusing on the flower structure of Korean Platanthera was examined. The genus Tulotis was included to the genus Plathanthera as previously suggested by many workers, because the diagnostic character to distinguish the two genera was not distinct enough. It is revealed that the taxon previously recognized as P. metabifolia was the misidentification of P. chlorantha and P. neglecta should be treated as a distinct species from P. mandarinorum. In result, Korean Platanthera were rearranged into 8 species; P. chlorantha, P. mandarinorum, P. neglecta, P. hologlottis, P. japonica, P. ophrydioides, P. ussuriensis, and P. fuscescens. A key to the species of Korean Plathanthera and taxonomic discussion of each species were provided.

Platanthera brevicalcarata Hayata (Orchidaceae), previously known to be distributed from Taiwan to southern Japan, was found in the Jeju-do, Korea. This species is distinguished from the related taxon Platanthera chlorantha by its small plant size, white sepal with distinct one green vein, and short-cylindrical spur. The local name Young-ju-je-bi-ran is originated from the local name of Mt. Halla. The morphological characters and illustration of the species are provided with line drawing and photograph from the natural habitat.

In this study, orchid mycorrhizal fungi (OMF) were isolated from four terrestrial orchids on Mt. Hambeak, Platnathera chlorantha, Platnathera mandarinorum, Cephalanthera falcate, and Cephalanthera longibracteata. OMF were identified using morphological and sequences analysis of fungal internal transcribed spacer (ITS) regions by specific primer of basidiomycetous orchid mycorrhizas; ITS1-OF and ITS4-OF. Four species of orchid mycorrhizal fungi were identified as Ceratobasidium sp, Epulorhiza anaticula, Tulasnella calospora and Tulasnella sp.

Total 7 moors, Yong-neup on Mt. Daeam, Chilbo Mt. moor, Dogapsa-neup on Mt. Wolchul, Wangdeungiae-neup on Mt. Jiri, Mujechi-neup on Mt. Jungjok, Buljae-neup on Mt. Kyungak and Geoinri-neup on Dongsang, were investigated by literatures and survey. Distribution, conditions, and similarity of dominant species and Orchidaceae on moor were analyzed. The results are follows; There are total 46 wetland plant species observed more than twice from 7 moors. The plants classified as constancy class V, which are appeared more than 80%, are Iris ensata var. spontane, Juncus effusus var. decipiens, Sanguisorba tenuifolia var. alba, Habenaria linearifolia, Sium ninsi, Lobelia sessilifolia, Lastrea theiyptoris, and Eupatorium chinensis var. simplicifolium. Highly appearing Orchidaceae, which was classified to constancy class IV plant, are Habenaria linearifolia, Pogonia japonica, Eipactis thunbergii, and Platanthera mandarinorum. They are the typical index plants of the moors. Habitual environment of Habenaria radiate and Platanthera hologlottis can be affected by environmental aspects such as latitude, altitude and the water quality. However those of Habenaria linearifolia, Epipactis thunbergii, and Pogonia japonica are not affected by latitude and altitude, but may be determined by water condition of wetland. As the result of similarity index analysis for appearance of Orchidaceae identifying each moors in the view of species composition, swamps at Dogapsa-neup and Buljae-neup are very similar. However Yong-neup is totally different from those of Dogapsa-neup and Buljae-neup. Yong-neup had shown the high similarity indices of 0.85 and 0.75 with Wangdeungiae-neup and Mujechi-neup, respectively. Growth properties of wild Orchidaceae at wetland were almost similar. Platanthera mandarinorum and Liparis kumokiri had characteristics of good adaptability. Most of them need light. Pogonia was the only long-day plant. The flowering time of these Orchidaceae was from May to September.

(1) Plants in the crater of Halla-San (Mt. Halla), a conical volcano that originated in the Tertiary period, were studied on three different occasions; July 1937, July 1955, and August 1957, and noted 52 familites, 149 species. In the latest study undergone in 1957, the authors collected 108 species. Notable species among them are Geranium Shikokianum Matsum which has not been reported in Korea, Clematis Chiisanensis Nakai, Lactuca Chelidonifolia Makino, and Platanthera Maximowiczana Schelchter which have not been reported in Jeu-Do(Island) so far. (2) Plants in To-Do(Island), territorial island of Jeju-do, were also studied. The authors noted Canavalia lineata D.C.non-reported Species in Korea, usually distributed along Southern Honshu, Shikoku, and Kyushu of Japna, Ryukyu and Taiwan. The overfall flora of the island is composed of 30 families, 44 Species; 5 Species of wood plants and 39 species of herbs, and is mostly of littoral plants.

We have investigated the vegetation in the peninsula located in Ongjeong-Li Seomyeon in Youngweol-gun. Since this is a limestone area, boxtrees, Abelia mosanensis T. H. Chung ex Nakai, and Selaginella stauntoniana Spring were abundant, as these are types of vegetation characteristic of limestone areas. Pinus densiflora S. et Z. was the most dominant woody plant, but vegetational changes, such as the dominance of Quercus variabilis Blume, Quercus dentata Thunb, and Quercus mongolica Fischer, were observed in spots. In particular, the growth of nursery plants of pinus densiflora S. et Z. was not observed, and young trees like Quercus mongolica Fischer grow as low vegetation of Pinus densiflora S. et Z.. Thus, the ecological succession of Quercus mongolica Fischer is predicted. Outside the investigation area, as herbaceous plants, various vegetations were observed, including Selaginella stauntoniana Spring, Thalictrum coreanum H. Lev., Mukdenia rossii(Oliv.) Koidz., Platanthera freynii Kraenzl., Cephalanthera longibracteata Blume, Potentilla dickinsii Franch., Patrinia rupestris(Pall.) Juss., Swertia pseudochinensis H. Hara, Vicia venosa(Willd.)
