  • Biological invasion of alien plants is considered to be one of the most serious threats to biodiversity in riparian zones. The effects of two invasive alien plants, Sicyos angulatus and Paspalum distichum var. indutum, on the flora and community structure of the riparian vegetation were investigated at 22 sites at streams in Korea. Sicyos angulatus has invaded the central Korean Peninsula. This alien plant has caused problems to stream managers because of its aggressive vining growth. It had suppressed native vegetation such as trees, shrubs and tall grasses on bank slope and higher floodplains. Paspalum distichum var. indutum has become more widespread in the southern part of Korea. This invasive plant has shallow rhizomes and creeping, extensively branched stolons. It forms a dense mat over lotic or slowly-flowing water and threatens submerged and short emergent hydrophytes. In order to control the introduction and expansion of alien plants, limitation of artificial disturbances and appropriate alien plant management are needed in riparian areas.

  • The vascular plants collected from Dongwol Valley in Mt. Gyeryongsan, national park were composed of all 248 taxa including cultivated species, and classified into 1 phylum, 4 classes, 3 subclasses, 34 orders, 84 families, 178 species, 33 varieties and 4 forms. As compared the flora of the commonly distributing species of this region with those of the southern part, the middle part, the northern part of the Korean Peninsula, Jeju-do Island and Ulreung-do Island, the proportion of them were $90.3\%,\;98.0\%,\;79.0\%,\;73.8\%$ and $62.1\%$, respectively. One taxon of the plants distributed only in the southern part, 3 taxa of those in the middle part, 5 taxa of those in the middle-northern part and 23 taxa of those in the middle-southern part were found in this Valley. Natural resource plants were categorized into edible 118 taxa, medicinal 78 taxa, industrial 46 taxa, ornamental 39 taxa, timber 14 taxa and fiber 9 taxa. Four taxa of the Korean endemic plants are distributed in Dongwol Valley. The vegetation of the valley is Quercus and Rhododendron mixed forest, and it belongs to the boundary between the middle part and the southern part in the floral zone of the Korean Peninsula.

  • Taxa of genus Callicarpa in Korea were described taxonomically and studied interspecific relationships, based on the leaf length, leaf width, peduncle length, fruit width and geograhic distribution. Among 12 taxa reported previously in Korea, 3 forms of C. japonica were unifed to original species, C. japonica var. glabra was reserved, Whereas C. shirasawana was not distributed in Korea. As a result, 7 taxa belonging to 3 species, 4 varieties of genus Callicarpa remained. C. japonica complex is considered to be more advanced among the species compared with the bract shapes.

  • To clarity the species of genus Melandrium (Caryophyllaceae) in Korea, the taxonomic characters were described and interspecific relationships were discussed to the extemal morphology with light and scanning electron microscopy. The position and size of appendages on petal, the shape and venation pattern of leaf, and the external morphology of seed and pollen were approved as the good characters to classify genus Melandrium in Korea. As the result, genus Melandrium in Korea could be arranged as 6 species, 1 variety, 1 forma. M. umbellatum was exclusively distributed in north Korea, and its taxonomic treatment was reserved.

  • Prunus choreiana, invalidly published without Latin description in the original text, is validated here. The species has been known as a Korean endemic plant species of deciduous shrub, and a typical calciferous plant mainly distributed in Pyeongnam Province and Hamnam Province, North Korea. However, recently new population was reported from Mt. Myon and another new population is reported here from Mt. Jabyeong in Gangwon-do.
