Flora investigations have been conducted by many researchers for a long time in Korea. Even though large amount of investigation data has been accumulated, there is no accurate statistics or database because most of data were published in a printed form. We developed a web-based database of flora investigation, named as the Integrated Korean Flora Database (http://www.floradb.net/) to understand distribution patterns and habitats of plants in Korea. Till now, 480 published paper, 356 thesis, 76 reports and books, and 8 unpublished papers written in between 1962 and 2017 were collected and their species lists from 280 papers were parsed into the database. From 124,105 records, 3,100 species belonging to 206 families and 965 genera were identified via comparing with two major Korean plant species lists. 55 endangered species, 159 endemic species, and 367 rare species were identified. The most frequently surveyed species were Commelina communis in herbaceous and Rosa multiflora in woody plants. Microclimate data provided by Korea Meteorological Administration were also integrated and analyzed to assign cold hardness zones for each species. By comparing minimum temperature (<2%) acquired from automated weather stations (AWS) near by plant species, 6a to 10b zones (7b is the most frequent zone) were identified. Integrated Korean Flora Database will be a fundamental platform of korea flora investigation as well as a new standard for classifying distribution of plants based on accurate microclimate data. Moreover, it can also provide evidences of investigated plant species, such as specimen and/or pictures with connecting to the InfoBoss Cyber Herbarium (http://herbarium.infoboss. co.kr/) and Biodiversity Observation Datbase (BODB; http://www.biodiversitydb.org/).

We investigated the bryophyte flora of the Gayasan Mountain National Park in Korea by conducting 18 field surveys in from April of 2009 to November of 2016 at various sites on the mountains. During the surveys, we discovered 204 taxa comprising 57 families, 106 genera, 199 species, 2 subspecies, and 3 varieties. Among these, 145 species were reported as new to the flora of Gayasan Mountain. A checklist based on a study of 903 specimens is provided. The most notable species recorded during the surveys were the rare bryophytes Hattoria yakushimensis (Horik.) R. M. Schust., Nipponolejeunea pilifera (Steph.) S. Hatt., Drepanolejeunea angustifolia (Mitt.) Grolle, Lejeuena otiana S. Hatt., Cylindrocolea recurvifolia (Steph.) Inoue and Pogonatum contortum (Menzies ex Brid.) Lesq.

We report 14 species of flowering plants as new additions to the flora of Laos. These are Illex viridis (Aquifoliaceae), Capparis erycibe (Capparaceae), Euphorbia bokorensis (Euphorbiaceae), Exacum darae (Gentianaceae), Aeschynanthus cambodiensis (Gesneriaceae), Tetraphyllum roseum (Gesneriaceae), Utricularia gibba (Lentibulariaceae), Macrosolen brandisianus (Loranthaceae), Decaschistia siamensis (Malvaceae), Nyssa yunnanensis (Nyssaceae), Adenia penangiana var. penangiana (Passifloraceae), Pentaphylax euryoides (Pentaphylacaceae), Wikstroemia bokorensis (Thymelaeaceae), and Debregeasia wallichiana (Urticaceae). We discovered the species during a botanical survey of the Phou Khao Khouay National Biodiversity Conservation Area (PKKNBCA) of Lao PDR in 2015-2019. In addition, nine rarely collected flowering plant species in Laos are newly reported for the PKKNBCA.

Protected Flora are natural heritage that involve a wide variety of valuable natural values and cultural values. Over time, "Cultural Properties Preservation Law" has been changing the definition and the criteria of Protected Flora. In addition to the academic value and the rarity of the plant, historical, ethnic and landscape values have become increasingly important. For that reason the declaration and management processes of the Protected Flora need to be improved. However, the current statute has focused on the morphological characteristics of the plants which have a limit to encompass various values of the plant. It also does not correspond to the definition of Protected Flora and its declaration criteria stated on the "Cultural Properties Preservation Law." For this reason, the main purpose of this study is to develop new types of Protected Flora so that various Protected Flora can be discovered in the future.

A new distribution of Scutellaria guilielmii A. Gray is discovered in Korea. This species was collected from seashores on Pyoseon-ri, Pyoseon-myeon, Seogwipo-si, Jeju-do. S. guilielmii is distinguished from other related Korean taxa of the genus by having broadly winged nutlets (fruits). Here, we provide a precise description, illustrations, key to the related taxa, and photographs of its habitat. The new Korean name is given as 'Nal-gae-gol-mu-kkot', considering the broadly winged nutlets (fruits). In addition, new habitats are likely to be discovered through plant biodiversity surveys of the southwestern coastal islands.

The marine algal flora of the Keret Archipelago ($66^{\circ}$ N, $33^{\circ}$ E) in the White Sea, Russia was investigated during 2008. Over 250 algal records from more than 15 islands and several sites on the adjoining mainland produced a total of 62 algal species. This raised the total from 56 to 88 species of Chlorophyta (23 species), Phaeophyceae (31 species), Rhodophyta (33 species), and Tribophyceae (1 species) of which seven were new records or verifications of ambiguous records for the White Sea and 11 species are new for the Keret Archipelago. The new or confirmed records included species of Blidingia, Eugomontia, Prasiola, Rosenvingiella, and Ulothrix (Chlorophyta), Acrochaetium, Colaconema (Rhodophyta), and Vaucheria (Tribophyceae). Five species of flowering plants (Aster, Plantago, Triglochin, and Zostera) were associated with the macrophytic algal vegetation of the region. Five fucoid algae in Pelvetia, Fucus, and Ascophyllum provide a picture of a temperate flora. Regardless, the overall species richness is consistent with an arctic nature to the flora. This discrepancy is attributed to the 'filter' provided by the Barents Sea of the Arctic Ocean for post-glacial colonization of the White Sea.

The last four years of joint botanical collections by the governments of Myanmar and South Korea in Natma Taung National Park and adjacent areas in the Chin State of Myanmar have revealed the presence of 20 naturally occurring species of angiosperms new to the flora of Myanmar. Plants not previously recorded include species originally considered to be only found in neighboring mega-diverse countries. Examples (e.g., for India) include Boehmeria manipurensis Friis & Wilmot-Dear (Urticaceae), Trigonotis hookeri Benth. ex C. B. Clarke (Boraginaceae) and Mycetia radiciflora (C. B. Clarke) Airy Shaw (Rubiaceae); those for China include Microtoena delavayi Prain (Lamiaceae), Pimpinella kingdon-wardii H. Wolff (Apiaceae) and Senecio diversipinnus Y. Ling (Asteraceae). The data presented in this report are expected to be useful sources for phytogeographical studies of these species.

The present study summarized the occurrence, distribution and autecology about 31 taxa of the green algae (Chlorophytes) collected from several swamps, reservoir and highland wet-lands in the South Korea from 2010 to 2013. This paper deals with a total 31 taxa including of 26 genera which are recorded for the first time in Korea. Among these algae, 18 genera including Pyrobotrys Arnoldi, Volvulina Playfair, Dicellula Svirenko, Echinocoleum Jao & Lee, Hofmania Chodat, Gloeotila Kutzing, Tetrachlorella Korschikov, Botryospherella P.C.Silva etc., were newly recorded in Korean fresh-water algal flora.
