The genus Acteniceromorphus is taxonomically reviewed for the first time in Korea. From the previously recorded three species, two species, A. selectus (Candèze, 1894) and A. fulvipennis (Lewis, 1894) are confirmed as misidientification of species which are endemic to Japan. Another species, A. chlamydatus (Lewis, 1894) is unavailable any Korean specimens. Additionally, we found A. ferrugineipennis (Candèze, 1879) as new to Korea. We also provide a comparison of DNA barcoding for two species previously misidentified and the newly recorded species, except A. chlamydatus. DNA barcoding result shows that each species is clearly delimited at species-level from each other by large interspecific genetic distance over 7.2%.

This study is based on crane fly specimens collected during more than 80 years, from 1937 through 2019, and are in collections maintained at the United States National Museum, Smithsonian Institution, Washington DC, USA; at Korea University collection, Seoul, South Korea, and the National Institute of Biological Resources, Incheon, South Korea. Three species belonging to genus Phylidorea Bigot, 1854 originally were described from North Korea and in total four species were known from the Peninsula. Phylidorea (Phylidorea) multidentata (Alexander, 1938) is a Korean endemic. We are adding P. (P.) melanommata (Alexander, 1921) to the list of Korean species, which was previously recorded from Japan and Far East of Russia. We present general information on genus and subgenera, redescriptions of species based on Korean specimens, illustrations of both sexes, elevation range, period of activity, habitat information, general distribution, and a distribution map for the Korean Peninsula (including North Korea) for each species.

Corchoropsis Siebold & Zucc. was traditionally included in Tiliaceae, however, several morphological characters and molecular phylogenetic studies supported that it was the member of Dombeyoideae (Malvaceae). It is used as compost, medicinal, and ornamental herbs. Out of total three species, two species and one variety, grow in Korea. Although it is an East Asian endemic genus, plastome data has not been defined. Here, we characterize the plastome sequences of C. tomentosa (160,093 bp) and C. tomentosa var. psilocarpa (160,724 bp). Corchoropsis encodes 78 protein-coding genes, 30 tRNAs, and four rRNAs with a pseudogene inf A. Phylogenetic study revealed that Tilioideae is sister of Dombeyoideae. This study will contribute to define the genome structures, phylogenetic, and evolutionary studies of the genus Corchoropsis.

Systematic studies for genus Anaphalis in Koreaare relatively scarce. As a fundamental step to further taxonomic studies of this genus, we here propose lectotype for A. morii, endemic taxa in Korea with a brief re-evaluation of its taxonomic entity. During the examination of herbarium specimen for A. morii, we found nine sheets of five collections in three herbaria. Among the original materials, we selected a specimen in TI which was first cited by the author and include an additional annotation, matching with his own description. Also, we were able to determine the taxonomic relationships between A. morii and its relatives, A. yakusimensis. Based on our observation, we identified that several morphological characters are clearly differ from A. yakusimensis occurring only Isl. Yakushima in Japan.

More than half of the global distribution of the Rhododendron genus is found in China, with over 74% being endemic species. However, there is still insufficient data to chemically classify the Rhododendron genus native to China. Therefore, in this study, a chemotaxonomic study was conducted to determine the presence of taxifolin-3-O-arabinopyranoside, a flavonoid compound, in the Rhododendron genus native to China. Forty-three species of Rhododendron native to China-20 from across China, 8 from Beijing, 6 from Yanbian, and 9 from Yunnan-were utilized in the experiment. Through HPLC analysis, the retention time was compared with that of taxifolin-3-O-arabinopyranoside, a standard compound, and quantitative analysis was conducted. As a result, taxifolin-3-O-arabinopyranoside was detected in 22 out of 43 the Chinese Rhododendron species. Afterwards, LC-MS/MS analysis was performed on the 22 species in which taxifolin-3-O-arabinopyranoside was detected to determine whether the molecular weight was consistent with the standard compound. Under negative conditions, it was confirmed that all samples exhibited the same molecular weight as taxifolin-3-O-arabinopyranoside, 435-436 m/z. The same compound was detected in more than half of the Rhododendron species used in the experiment, and taxifolin-3-O-arabinopyranoside was determined to be an indicator compound for Rhododendron species native to China. In addition, the possibility of using the above results as basic data for chemical classification of Chinese Rhododendron genus was confirmed.

The chloroplast DNA sequences of Megaleranthis saniculifolia, an endemic and monotypic endangered plant species, were completed in this study (GenBank FJ597983). The genome is 159,924 bp in length. It harbors a pair of IR regions consisting of 26,608 bp each. The lengths of the LSC and SSC regions are 88,326 bp and 18,382 bp, respectively. The structural organizations, gene and intron contents, gene orders, AT contents, codon usages, and transcription units of the Megaleranthis chloroplast genome are similar to those of typical land plant cp DNAs. However, the detailed features of Megaleranthis chloroplast genomes are substantially different from that of Ranunculus, which belongs to the same family, the Ranunculaceae. First, the Megaleranthis cp DNA was 4,797 bp longer than that of Ranunculus due to an expanded IR region into the SSC region and duplicated sequence elements in several spacer regions of the Megaleranthis cp genome. Second, the chloroplast genomes of Megaleranthis and Ranunculus evidence 5.6% sequence divergence in the coding regions, 8.9% sequence divergence in the intron regions, and 18.7% sequence divergence in the intergenic spacer regions, respectively. In both the coding and noncoding regions, average nucleotide substitution rates differed markedly, depending on the genome position. Our data strongly implicate the positional effects of the evolutionary modes of chloroplast genes. The genes evidencing higher levels of base substitutions also have higher incidences of indel mutations and low Ka/Ks ratios. A total of 54 simple sequence repeat loci were identified from the Megaleranthis cp genome. The existence of rich cp SSR loci in the Megaleranthis cp genome provides a rare opportunity to study the population genetic structures of this endangered species. Our phylogenetic trees based on the two independent markers, the nuclear ITS and chloroplast MatK sequences, strongly support the inclusion of the Megaleranthis to the Trollius. Therefore, our molecular trees support Ohwi's original treatment of Megaleranthis saniculifolia to Trollius chosenensis Ohwi.

The purpose of this study was to investigate changes in vegetation and flora after five years through field surveys data with the Han Gang Watershed Management Committee (2013) data in order to observe natural vegetation changes in the riparian zone of Han River watershed. As a result, the flora of the riparian zone in 2012 were listed total 231 taxa, 66 families, 158 genus, 207 species, 23 varieties, and 1 forms, and in 2017, a total 247 taxa, 74 families, 174 genus, 218 species, 27 varieties, and 2 forms were identified. The number of rare plants decreased from 4 taxa in 2012 to 2 taxa in total in 2017, and the number of endemic plants increased from 1 taxa to 3 taxa. The number of specific plants by floral region decreased from 21 taxa (9.1% of all 231 taxa of flora) in 2012 to 16 taxa (6.5% of all 247 taxa of flora) in 2017. The total number of naturalized plants is analyzed to increase from 35 taxa, a naturalization rate of 15.15% (all 231 taxa of flora) and urbanization index of 11.2% (all 312 taxa of naturalized plants) in 2012 to 44 taxa a naturalization rate of 17.8% (all 231 taxa of flora) and urbanization index of 14.1%(all 312 taxa of naturalized plants) in 2017. The ecosystem disturbance species showed an increase in both number of species and cover degree grades, indicating that the riparian zone changed in a negative direction.
