Five unrecorded species (Oedipodium griffithianum, Myurella tenerrima, Trachypus bicolor, Coscinodon humilis, Meteorium miquelianum subsp. atrovariegatum) with one unrecorded family and two unrecorded genera, were reported as new to the Korean moss flora. The monotypic family Oedipodiaceae consisting of a single genus and single species was distinguished from Splachnaceae by small plants that were 10 mm in length simple or sometimes branched, obovate-spathulate to ${\pm}$ orbicular, costa ending below the apex and entire margins except for the lower long-ciliate portion The species was first found at the top of the Mt. Seorak at an altitude of 1708 m. The two genera, Myurella and Coscinodon were found in the Korean Peninsula. Myurella tenerrima (Theliaceae) was found around the top of Jung-bong on Mt. Jiri. It was mixed with other mosses in the crevices of rocks in the alpine regions. The species is similar to M. sibirica, yet it can be distinguished by the position of papilla in the median laminal cells. Coscinodon humilis (Grimmiaceae) were found on the ridge of Mt. Gaya. C. humilis has a variety of hyaline apex according to leaf position and forms a capsule so it can be distinguished by family. Trachypus bicolor and Meteorium miquelianum subsp. atrovariegatum are unrecorded species. T. bicolor (Trachypodaceae) were found on the ridge of Mt. Gaya. T. bicolor is similar to T. humilis but distinguished by the costal lengths of the leaves. M. miquelianum subsp. atrovariegatum (Meteoriaceae) was found in Gageo-do. This species was distinguished by the plant form and morphology of stem leaves in the same genus.

Water-soluble crude polysaccharide (TM-1) prepared from the leaves of Teucrium viscidum var. miquelianum was fractionated into three polysaccharide fractions, TM-2, TM-3 and TM-4 by the addition of cetyltrimethylammonium bromide. The major polysaccharide fraction, TM-2, consisted of glucose, galactose, rhamnose, mannose, glucuronic acid and galacturonic acid, and all fractions contained galactose and glutose as the major neutral sugars. TM-4 showed the highest anti-complementary activity. When TM-4 was futher fractionated by anion exchange chromatography, TM4- II a and TM4-II b showed the most Potent anti-complementary activity. TM4- II a was composed mainly of galactose, arabinose and glucose in the molar ratios of 2.13 : 0.94 : 1.00 respectively, and contained a small amount of galacturonic acid and glucuronic acid.

To investigate the flora of wetland at Mt. II-Kwang, the helophyte of the mountain was examined. The flora observed was classified into 2 phyla, 15 families, 27 genera, and 34 species. Representative species at the wetland were Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, Eriocaulon miquelianum, and Eleocharis attenuata var. laeviseta. In the lower part of the wetland, water was abundant and soil surface layer was thin, and Eriocaulon miquelianum-Carex canescens-Drosera rotundifolia, community were developed. On the other hand, in the upper part of the wetland, water was not abundant and soil surface layer was thick, and Agrostis clavata-Phragmiles japonica community were community were developed. Utricularia bifida and Utricularia yakusimensis were growing abundantly at this wetland, but Utricularia racemasa was few in number and narrow in the distribution area. Eriocaulon miquelianum, a Korean endemic plant, was observed, and Habenaria linearifolia, Spiranthes amoena, and Epipactis thunbergii, the CITES plant, were observed at this wetland. Insectivorous plant such as Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, and Utricularia yakusimensis were also observed.

Lilium Miquelianum Makino is a species which originated in Korea. The Karyotype of the species was examined in materials collected at Mts. Kaya, Kasan, Chejung, and Kaji. The results are as follows: 1) The somatic chromosome number was found to be 2n=24. 2) The karyotype is described as: K=2Am＋2Bkm＋2Csst＋2Dsst＋2Ests＋2Fst＋2Gst＋2Hst＋2Ist＋2Jsst＋2Kst＋2Lst m: metacentric, sm: submetacentric st: subtelocentric, s: secondary constriction 3) A single subcentric supernumerary B-chromosome was found in some bulbs from Mt. Kasan. 4) The shape of the supernumerary B-chromosome was similar to that of the E chromosome which had separated at its secondary constriction and lost its lower chromosome fragment. 5) From three to eight nucleio of varying sizes were found in the telophase or interphase nucleus of root tip cells. The maximum number of eight nucleoli corresponds to the number of chromosomes that have a secondary constriction.

In the Sumeunmulbaengdui Wetland Protected Area of Jeju Island, there exists a unique pond, a so-called 'Ohmi', which is likely to be an oasis supporting the wildlife and escaped-livestock. We exquisitely described the diversity and distribution of plant community of the Ohmi. Despite its small area, six syntaxa were identified: Sphagnum community of peat bog type, Nymphoides coreana community of the floating-leaf limnetic vegetation, Scirpus triangulatus community and Schoenoplectus hotarui community of the littoral zone vegetation, and Deinostema violacea-Eleocharis congesta community and Eriocaulon atrum-miquelianum community of the ephemeral vegetation. A zonal distribution of plant communities along the water depth was recognized. The Sphagnum islets regarded as a typical component of peat bog, in Korea were first described at the center of the Ohmi. We conclude that the Ohmi is a primeval keystone habitat of the Sumeunmulbaengdui intermediate moor with a less oligotrophic ombrotrophic environment.
