  • Silene fissipetala Turcz., which is native to Continental China and Taiwan, was newly found in Chungcheongnam-do, Korea. S. fissipetala is similar to the related taxa S. antirrhina L., S. armeria L., and S. koreana Kom. in that it has glutinous zones. However, S. fissipetala is distinguished from the congeneric species by the presence of laciniate at the petals. The species grows on slopes and roadsides, suggesting that it is likely to have been introduced through the installation of green sites and road construction. A precise description, photographs, voucher specimens and a key to related taxa are provided.

  • Phytoplanktons were collected from various environments including small marshes, small ponds, reservoirs and brackish water from March 2017 to November 2017. In this study, five species of family Scenedesmaceae were newly recorded in Korea. The genus Desmodesmus was newly reported in Korea. The newly recorded species are Scenedesmus nanus, S. praetervisus, Desmodesmus costato-granulatus, D. lunatus and D. spinulatus. S. nanus and S. praetervisus are known to occur in freshwater, but they were found in the brackish water in this study.

  • This study aimed to elucidate the distribution of vascular plants on the Deok mountain in Ganghwa-gun, Korea. The results of 10 field surveys from March to October of 2019 identified 532 taxa in total, representing 482 species, 9 subspecies, 39 varieties, 1 form, and 1 hybrid in 318 genera and 105 families. The plant formation of Deok mountain is the deciduous broad-leaved and conifer mixed forest, which is the common one in the middle region of the Korean Peninsula. Among them, 301 taxa were newly recorded in this study, 7 taxa were endemic plants to Korea, 3 taxa were red list plants. The floristic target plants amounted to 41 taxa, specifically 1 taxon of grade V, 2 taxa of grade IV, 7 taxa of grade III, 9 taxa of grade II, and 22 taxa of grade I. Alien plants were recorded a total of 73 taxa with a naturalized index of 13.7%, the urbanization index was calculated to be 11.8% and 4 taxa were ecosystem disturbance plants.

  • This study summarizes the taxonomic notes and distribution of 13 taxa of the genus Scenedesmus (Chlorophyceae) collected from several swamps, reservoirs, and rivers throughout South Korea from 2012 to 2014. In this study, light microscopy images of all 13 taxa are presented and briefly discussed with regard to their taxonomy, distribution, and ecology and environmental factors of occurrence sites. All 3 subgenera (subgenus Scenedesmus 1 taxon; subgenus Acutodesmus 2 taxa; subgenus Desmodesmus 10 taxa) are newly described in Korean freshwater algal flora: S. linearis, S. acuminatus var. elongatus, S. acuminatus var. tetradesmoides, S. carinatus, S. denticulatus var. disciformis, S. gutwinskii var. heterospina, S. helveticus f. bicaudatus, S. lefevrei, S. oahuensis var. clathratus f. longiclathratus, S. oahuensis var. clathratus, S. pannonicus, S. polydenticulatus, and S. tenuispina.

  • A study on Chlorococcal algae was carried out at 33 stations (ponds, swamps, reservoirs, lakes and rivers) from May 2009 to January 2013. The families Hydrodictyaceae and Coelastraceae of order Chlorococcales were investigated, including 5 genera, 29 species, and 17 varieties. Among them, 8 taxa were newly recorded for Korea; 1) Family Hydrodictyaceae: Pediastrum asymmetricum, P. boryanum var. campanulatum, 2) Family Coelastraceae : Actinastrum aciculare, A. hantzschii var. subtile, Coelastrum indicum, C. microporum var. octaedricum, C. morus, C. pulchrum.

  • A study on Chlorococcal algae was carried out at 21 stations (ponds, swamps, reservoirs, lakes and rivers) from May 2011 to January 2012. The families of Botryococcaceae and Characiaceae of Chlorococcales were investigated to the extent of 8 genera, 20 species. Among them, 10 taxa are newly recorded in algal flora of Korea by Kim and Kim (2012) and this study reviewed about ; 1) Family Botryococcaceae: Dictyosphaerium elegans, D. reniforme, D. simplex, D. elongatum, 2) Family Characiaceae: Characium conicum, Ankyra ancora, A. judayi, A. calcarifera, Schroederia spiralis, S. indica.

  • Six taxa of unrecorded Korean species of charophytes are described. Freshwater and aerial charophytes were collected from the bark of trees, reservoirs, small ponds and swamps from April 2017 to September 2017. The newly recorded species of Korea were Cosmarium quadrifarium f. octastichum, Euastrum turneri, Spondylosium nitens var. triangulare, Staurastrum kouwetsii, Staurodesmus dickiei var. latus, and Klebsormidium subtile. K. subtile was transferred from Stichococcus subtilis.

  • In this study, aquatic and aerial algae were collected in various environments in Hongcheon-river of Gangwan-do between December 2011 and June 2012, with the aim of adding newly described genera and species to the Korean flora. As a result, five genera and eight species were recorded for the first time in Korea. These newly recorded genera and species were Cylindrocapsa geminella, Leptosira mediciana, Pseudendoclonium basiliense var. brandii, Stichococcus minor, S. deasonii, Eustigmatos polyphem, Nephrodiella lunaris, and Xanthonema exile. The eight taxa identified in this study mostly corresponded to their reported morphological characteristics. However, some differences from previous published descriptions were found; N. lunaria, reported to be an aquatic species in a previous study, was found to be an aerial algae inhabiting on rocks and mosses. Cylindrocapsa geminella was found to transform into attached or planktonic algae depending on the environmental condition, and the cell wall was found to be changed. Likewise, E. polyphem was seen to change cell-shape or chloroplast color according to the environment.
