  • This study was conducted to investigate the flora of Mt. Myongji and also to find the distribution characteristecs of rare and endangered plants in this mountain. Field surveys were carride out 21 times from 1991 to 1997. Main results obtained from this study were as follows; 1. Mt. Myougji was covered with Pinus koraiensis and Sarix leptolepis stands at the altitude lower than 600m, and deciduous forests which were consisted of Quercus mongolica, Carpinus sp., Acer sp., Cornus sp., Fracinus sp., etc. occupied at the altitude higher than 600m. Dicentra spectabilis population and Anemone population were remardable, and Adenophora grandiflora and Astilbe chinensis var. davidii with white flowers were found. 2. The vascular plants in Mt. Myoungji were recorded as 677 taxa such as 19 families, 358 genera 576 species 90 varieties 11 forma. Among them. 19 families 31 genera 32 taxa were endemic plants and 27 taxa were naturalized plants. 3. 26 taxa of rare and endangered plants protected by Forestry Administration were found in Mt. Myonfji. Among them, Asarum maculatum. Hanabusaya asiatica, Lilum cernum. Jeffersonia dubia, and Cypripedium japonica populations could be regarded as very important in a biogeraphical aspect. So it is necessary to monitor this area in a long term and to establish the conservation strategies.

  • We investigated the flora of Mudeung-san (Mt.) located in Gwangju-gwangyeoksi, Hwasun-gun and Damyang-gun and discussed the vascular plants found there. 22 days separate fild trips were completed from March of 2009 to November 2011. As a result, we identified the distribution of 816 taxa in Mudeung-san (Mt.), comprising 123 families, 441 genera, 668 species, 5 subspecies, 121 varieties and 18 forms. There are a total 111 taxa of floristic regional indicator plants. The floristic regional indicator plants are as follows; nine taxa of level V such as Gastrodia elata Blume, six taxa of level IV such as Hylomecon hylomeconoides T. Lee, 21 taxa of level III such as Stewartia korena Nakai, 18 taxa of level II, and 66 taxa of level I. In addition, two critically endangered species (CR), Galeola septentrionalis Rchb.f. and Paeonia obovata Maxim., two endangered species (EN), Dryopteris cycadina (Franch. & Sav.) C.Chr. and Jeffersonia dubia Benth., and eight vulnerable species (VU), such as Lilium callosum Siebold & Zucc, were found in the investigated area. Also, 14 endermic plants of Korea, such as Salix koriyanagi Kimura and Aconitium chiisanense Nakai, were found.

  • The ethanol extract of 77 species of edible and medicinal plants were examined antimicrobial activity against 5 strains of Listeria monocytogenes ATCC 19111, ATCC 19112, ATCC 19113, ATCC 19114 and ATCC 15313 by optical density using Bioscreen C. The ethanol extract of Siegesbeckia glabrescens Makino, Jeffersonia dubia Benth, Aquilaria agallocha Roxburgh, Lysimachia clethroides Duby and Nardostachys chinensis Batal. exhibited comparatively strong growth inhibition effect on 5 strains of L. monocytogenes at 1000 ppm level in broth. The minimum inhibitory concentration (MIC) of ethanol extract of Lysimachia clethroides Duby was $100{\sim}500\;ppm$ on 5 strains of L. monocytogenes. The MIC of the n-hexane and chloroform fraction of the extract were same concentration as $50{\sim}100\;ppm$. The n-hexane fraction of Lysimachia clethroides Duby showed strong growth inhibition at 25 ppm on Vibrio parahaemolyticus for 72 hr at $30^{\circ}C$ and at 50 ppm on Bacillus cereus and at 500 ppm on Staphylococcus aureus and Escherichia coli.

  • The flora in the region of Songnisan National Park ($N36^{\circ}28^{\prime}05^{{\prime}{\prime}}{\sim}36^{\circ}46^{\prime}38^{{\prime}{\prime}}$, $E\;127^{\circ}47^{\prime}06^{{\prime}{\prime}}{\sim}127^{\circ}57^{\prime}50^{{\prime}{\prime}}$) was surveyed from April 2000 to July 2006. Vascular plants in 26 collections included a total of 723 taxa: 115 families, 392 genera, 629 species, 4 subspecies, 72 varieties and 18 forms. Ninety-three of these taxa were first records for the region. In the flora of Songnisan National Park, 27 taxa were Korean endemic plants, 19 taxa were rare and endangered plants as designated by the Korea Forest Service. Forty-five of the taxa were with the levels III, IV, V in the floristic regional indicator plants which was designated by Korean Ministry of Environment, and 29 taxa were alien plants now naturalized in Korea. Owing to their unusual phytogeography and low number of populations, the taxa Crypsinus hastatus (Thunb.) Copel., Paeonia japonica (Makino) Miyabe & Takeda, Jeffersonia dubia (Maxim.) Benth. & Hook.f. ex Baker & S.Moore, Bupleurum euphorbioides Nakai, Phacellanthus tubiflorus Siebold & Zucc., Lilium cernuum Kom., Gastrodia elata Blume and Cephalanthera erecta var. subaphylla (Miyabe & Kud ) Ohwi were considered the most important. Based on these results, it is clear that appropriate plans to conserve the natural habitat of Songnisan National Park must be made immediately.

  • The flora of vascular plants in the mountains located in the Uiryeong-gun area, in the South province of the Korean Peninsula, such as Jagul-san(897.1 m), 676 Highland(676 m), Byeokhwa-san(522 m), and the Bangeo-san(530.4 m), was investigated between April 2008 and August 2009. These investigations found 580 taxa consisting of 496 species, 1 subspecies, 77 varieties, and 6 forms, found within 319 genera under 103 families. The count totaled at 744 taxa(16.2% of all vascular plant taxa in Korea), which was made up of 648 species, 3 subspecies, 81 varieties, and 12 forms, found within of 362 genera under 109 families, when voucher specimens from the previous research studies were added. Forests of the investigated areas were generally composed of mixed Pinus densiflora and Quercus sp. The areas with comparatively excellent vegetation were the valley neighboring Baekun-sa(temple) (in the eastern slope of Mt. Jagul-san), the southwest slope of Mt. 676 Highland, the eastern slope of Mt. Byeokhwa-san, and the northern slope of Mt. Bangeo-san. 10 families were collected in abundance: Compositae, Graminae, Leguminosae, Liliaceae, Rosaceae, Cyperaceae, Labiatae, Polygonaceae, Ranunculaceae, and Violaceae these families made up 50% of all collected taxa. 19 taxa were endemic to the area, including Salix hallaisanensis H.Lev, S. koriyanagi Kimura, Aconitum austrokoreense Koidz, A. pseudolaeve Nakai, Clematis trichotoma Nakai, Thalictrum uchiyamai Nakai, Stewartia pseudocamellia Maxim, Philadelphus schrenkii Rupr., Lespedeza ${\times}$ robusta Nakai, Vicia chosenensis Ohwi, Euonymus trapococca Nakai, and Angelica cartilagino-marginata var. distans(Nakai) Kitag. Eight of the taxa were rare and endangered plants, as designated by the Korea Forest Service, including Jeffersonia dubia(Maxim.) Baker & S. Moore and Viola diamantiaca Nakai. 38 taxa of alien plants were found. Vegetation of the surveyed areas falls in the South province of the Korean Peninsula. Of all the taxa collected, 463 taxa(10.06% of all vascular plants in Korea) are considered useful plants, 231 taxa are edible, 193 taxa have medicinal uses, 65 taxa are used ornamentally, 234 taxa are important forage, 3 taxa are used as an industrial raw material, 17 taxa are used for timber, 18 taxa contain useful dyes, and 7 taxa are used for fiber.
