  • Saussurea pseudogracilis Kitam. is characterized by its slender leaves, small involucre and small number of involucral bracts compared to Saussurea gracilis Maxim. But some taxonomists insist that it is hard distinguih S. pseudogracilis from S. pseudogracilis. We tried to discern taxonomic identification of S. pseudogracilis by measuring and analyzing 45 qualitative characters and 42 quantitative characters on 165 specimen. S. pseudograilis was not distinguished from S. gracilis not only by qualitative characters but also by quantitative characters even on statistical analysis(PCA). Therefore, S. pseudogracilis is not independent taxonomic species and it is proper to consider S. pseudogracilis as a synonym of S. gracilis.

  • The purpose of this study is to present the basic data for establishing the management plan of forest ecosystem in Honam-Jeongmeak and Geumnamhonam-Jeongmaek by surveying and analysing the vascular plants distributed in Jangansan(A-site), Palgongsan(B-site), Mandeoksan(C-site), Chuwolsan (D-site), Cheonunsan(E-site) and Jeamsan(F-site). The numbers of flora were 813 taxa including 115 families, 406 genera, 700 species, 4 subspecies, 94 varieties and 15 forms. There were 500 taxa in A-site, 427 taxa in B-site, 402 taxa in C-site, 449 taxa in D-site, 345 taxa in E-site and 524 taxa in F-site. The rare plants were 12 taxa including Paeonia japonica, Iris minutoaurea, Chloranthus fortunei and so forth. In IUCN Red List categories, there were 1 taxon of EN, 2 taxa of VU, 8 taxa of LC and 1 taxon of DD. The Korean endemic plants were 20 taxa including Salix koriyanagi, Thalictrum actaefolium var. brevistylum, Saussurea pseudogracilis and so forth. The specific plants by floristic region were 108 taxa including 58 taxa of grade I, 30 taxa of grade II, 16 taxa of grade III, 2 taxa of grade IV and grade V, respectively. The plants adaptable to climate change were 18 taxa including 11 taxa of southern plant and 7 taxa of northern plants. The naturalized plants were 49 taxa including Rumex nipponicus, Brassica juncea, Trifolium repens and so forth. The invasive alien plants were 4 taxa including Rumex acetocella, Solanum carolinense, Ambrosia artemisiifolia and Aster pilosus.

  • The vascular plants of this site were identified as 641 taxa through field investigation; 101 families, 340 genera, 547 species, 80 varieties, 12 forms, 1 subspecies and 1 hybrid. Based on the Rare plants of the Forest Service and Korea Forest Research Institute, 9 taxa were listed except implanted species; Loranthus tanakae, Aristolochia manshuriensis, Aristolochia contorta, Viola albida, Cypripedium macranthum, Schpolia japonioa, Acanthopanax chiisanensis, Rhododendron micranthum. Based on the Korean endemic plants, 18 taxa were listed; Salix purpurea var, japonica, Asarum sieboldii var. mandshuricum for. misnadrum, Persicaria lapathifolia for. alba, Pseudostellaria sylvatica, Aconitum pseudolaeve var. erectum, Corydalis maculata, Corydazis albipetala, Corydalis grandicazyx, Cardamine amaraeiormis, Chrysosplenium barbatum, Filipendula glaberrima, Lespedeza x tomentella, Acanthopanax chiisanensis, Melampyrum setaceum var. nakaianum, Weigela subsessilis, Adenophora triphylla var. hirsute, Cirsium setidens, Saussurea pseudogracilis. Specific plant species by floral region were total 81 taxa (12.6%); Prunus yedoensis in class V, 13 taxa (Thuja orientalis, Cimicifuga heracleiiolia, Sedum middendorffianutn, Rhododendron micranthum, etc.) in class IV, 17 taxa (Equisetum palustre, Aceriphyllum rossii, Angelica gigas, Cirsium setidens, etc.) in class III, 15 taxa (Heloniopsis orientalis, Lychnis cognata, Saxifraga oblongifolia, Viola orientalis, etc.) in class II, 35 taxa (Hosta capitata, Cimicifuga simplex, Chrysosplenium flagelliferum, Campanula punctata, etc.) in class I. So, the naturalized plants were listed 53 taxa and the naturalization index was 8.2%, urbanization index was 20.7%.
