Seventeen taxa including 17 species of 15 genera of 9 families were investigated for naturalized plants and ratio of naturalization was 13.6 percents at the study sites. Glehnia littorolis Fr. Schm. and Lilium callosum S. et Z. appeared as rare and endangered plants designated in Korea Forest Service. Nine taxa in degree 1, 2 taxa in degree 2, 4 taxa in degree 3, 2 taxa in degree 4 and 2 taxa in degree 5 were represented for especialized species.

Arctium tomentosum Mill. (Asteraceae), from Ulaanbaatar in the Khentei phytogeographical region of Mongolia, is recognized here as a new genus and species of the flora of Mongolia. Arctium differs from other genera of Asteraceae by the hooked apex of the involucral bracts. While A. tomentosum is most similar to A. lappa, it is easily distinguished by the glandular hairs of the corolla limb and the widened inner involucral bracts. Taxonomic notes, a description of the morphology, detailed photos, habitat information, the phenology and a distribution map of A. tomentosum are provided.

This study was carried out to investigate the flora of Is. Gageo (Jeollanam-do). The vascular plants were collected 13 times (from June 2008 to September 2011), and 465 taxa in total were identified, including 112 families, 301 genera, 402 species, 3 subspecies, 49 varieties, 9 forms and 2 hybrids. 171 taxa were first records for the region. Among them were seven taxa of Korean endemic plants and the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as three taxa. There were 54 taxa of the flora with the levels III, IV, V in the floristic indicator plants which was designated by Ministry of Environment. The naturalized plants were identified as 29 taxa, and their naturalization ratio and urban index were found to be 6.2% and 9.0% respectively. There existed many kinds of plants resources having conservational value like $Loxogramme$ $salicifolia$, $Sarcandra$ $glabra$, $Osmanthus$ $insularis$, $Saussurea$ $polylepis$, $Carex$ $ligulata$ var. $austrokoreensis$, $Hosta$ $jonesii$, $Cyrtosia$ $septentrionalis$, etc., in this area. As therefore clear that appropriate plans to conserve the natural habitat of Is. Gageo must be made immediately.

This study was performed to investigate the flora and plant resources of Mt. Woosanbong (537.8 m) from April to October 2002. The collected vascular plants were composed of all 389 taxa including cultivated species, and classified into 329 species, 2 subspecies, 53 varieties, and 5 forms of 248 genera under 81 families. Six taxa of the Korean endemic plants and 4 taxa of the rare and endangered plants were also distributed in this mount. Resource plants were categorized into edible 181, pasturing 160, medicinal 136, stainable 94, ornamental 77, timber 22, fiber 5 and industrial 4 taxa, respectively. Floristic geography of the investigated area was regarded as the boundary between middle and southern parts in floristic pattern of the Korean Peninsula.

The flora of Mt. Kum.lung(80 lm) was Investigated to compare the flora of Mt. Hwang-Ryung, Mt. Cheon-Hwang, Mt. Chulseo. The vascular plants, collected from March 1995 to Oct., 1996, were consisted of a total 564 taxa: 103 families, 312 genera, 493 species, 1 subspecies. 66 varieties and 4 forms. The Korean endemic plants of this area were 11 taxa, the alplan and endangered plants were 29 taxa, the special wild plants designatlrlg by Enoronmental Agency were 2 taxa and the alpian plants were 18 taxa. Because many plants, being necessary to conserve, are distributed Kumjung, but if development is indespensable. destruction of natural ecosystem must be minimized.

This study was carried out to investigate the flora of six islands belonging to the Gogunsan Archipelago (i.e., Sinsi-do, Seonyu-do, Munyeo-do, Yami-do, Bian-do, and Duri-do) in the Korean Peninsula. As results of five field surveys from March to October of 2016, we have identified 575 total taxa, representing 527 species, five subspecies, 42 varieties, and one hybrid, placed in 358 genera and 118 families. Of these 575 taxa, four are endemic to Korea, six taxa are listed on the Korean Red List of threatened species, 67 are floristic regional indicator plants, and 74 are invasive alien species. In this study, we compared species richness among the islands, and find that the larger the islands, the higher the species richness. In the case of habitat affinity types, forest species were most common, followed by farmland, seacoast, bare ground and wetland species. From similarity analyses based on the composition of vascular plants, each island did not exhibit either local specificity or unique diversity. On the contrary, the proportion of invasive alien and ruderal species may increase by human activities. Investigations and analyses of island flora such as this are important to assess the current status of the flora, predict future vegetation patterns and the spread of the alien species, and establish managment plans of plant diversity.
