Amynthas diffringens (Baird, 1869) is deemed valid yet comparable to A. corticis (Kinberg, 1867) and to A. nipponicus (Beddard, 1893) or A. peregrinus (Fletcher, 1896). Its syntypes tend to more genital markings than usual as shown for variable specimens from Japan, Korea, and Australasia that comply genetically with either of two A. corticis spp. groups. A. diffringens type-locality was UK hothouses yet closest specimens appear in part of A. heteropodus (Goto & Hatai, 1899) (=A. corticis) from Japan. Japanese Amynthas divergens (Michaelsen, 1892) is restored based on its serrate intestinal caeca. Meanwhile, the lectotype of Amynthas pingi (Stephenson, 1925) is deemed a synonym of A. carnosus (Goto & Hatai, 1899) compliant with Kobayashi's (1936) types III & II. Erstwhile A. pingi synonym A. fornicatus (Gates, 1925) is again included, but A. hongkongensis (Michaelsen, 1910) and A. chungkingensis (Chen, 1936) are provisionally retained whilst A. carnosa lichuanensis Wang & Qiu, 2005 is given separate species status. A new Korean taxon is proposed as A. carnosus naribunji sub-sp. nov. and two replacement names are provided: A. zhuya nom. nov. for homonym A. montanus Qiu & Sun, 2012 from Hainan and A. yizhou for A. carnosus sensu Shen et al., 2005 from Taiwan. No attempt is made to fully resolve numerous Japanese synonyms of A. carnosus [eg Ishizuka's (2001) invista, subterranea, subalpina, umbrosa, mutabilis, nubicola, plus A. nonmonticolus Blakemore, 2010] nor Korean synonyms [eg kyamikia Kobayashi, 1934, monstrifera Kobayashi, 1936 and murayamai Kobayashi, 1938, sangyeoli, youngtai (with segments miscounted), kimhaeiensis, sinsiensis and baemsagolensis - all names by Hong & James (2001) plus ?A. sangumburi Hong & Kim, 2002 (its segments miscounted too)] also A. fuscus Qiu & Sun, 2012 from Hainan and Taiwanese monsoonus James et al., 2005 plus A. penpuensis Shen et al., 2003 and A. taiwumontis Shen et al., 2013 syns. nov.. All synonyms remain in the currently defined A. carnosus pending full revisons although several may eventually comply with parts of prior A. corticis s. lato.

To examine the seed morphology in Korean Orobanchaceae, seeds of 5 species including 1 variety in five genera and one related taxon, Boschniakia himalaica Hook. f. & Thomson in Hook. f. from the Himalaya (7 taxa in total) were investigated by scanning electron microscopy (SEM). Two different seed types are recognized depending on three characters (e.g, .the seed size, seed coat structure and seed number per fruit). - Type I: size less than 1mm, seed coat structure reticulate and seed number per fruit more than ca. 1,000; Type II: size more than 1 mm, exotesta irregularly crested and seed number per fruit less than 1,000 (Lathraea japonicu Miq.). In Type I, three subtypes of exotesta internal surface pattern can also be classified; (1) Subtype Ia: reticulate - include irregularly striate (Ia') and deeply reticulate (Ia"), (2) Subtype Ib: foveolate, (3) Subtype Ic: smooth. Systematics application of the seed morphological data for the Korean Orobanchaceae is also briefly discussed.

Lycopus charkeviczii Prob. (Lamiaceae Martinov) is found in all provinces of the Korean Peninsula, excluding Jeju-do. This species is closely related to L. lucidus Turcz. ex Benth., having such characters as persistent calyx of which the length is longer than the nutlets, and narrowly lanceolate to oblong-lanceolate leaves. However, it is distinguished from L. lucidus by its parted calyx and its smooth or rarely glandular nutlets with an irregularly toothed apex. This taxon was named 'San-swip-ssa-ri' in Korean based on its habitat. We provide a description, illustrations, photographs, and a key of related taxa in Korea.

We investigated the area around four moors from May 2009 to June 2010 for plant diversity in Moojechineup, officially designated as the Ramsar wetland. The vascular plants of Moojechineup at Mt. Jeongjok were recorded as total 149 taxa, 55 families, 105 genera, 128 species, 1 subspecies, 16 varieties, and 4 forms. Rare plants were observed 7 taxa (Eriophorum gracile Koch, Drosera rotundifolia L., Iris ensata var. spontanea (Makino) Nakai, Kobresia bellardii (All.) Degl, Utricularia bifida L., Utricularia racemosa Wall., Utricularia yakusimensis Masam.). Korean endemic plants were 1 taxon, floristics special plants were 19 taxa, and naturalized plants were 3 taxa. Phytogeographical and evolutionarily, Eriophorum gracile is an important species; hence, further studies are needed to conserve it. Moojechineup is similar to the Shinbulsan wetland in terms of wetland plants (hydrophytes). Moojechineup's flora changes are in process slowly compared to earlier work; thus, continuing interest and appropriate measures should be encouraged.

We report a newly naturalized species of the genus Bidens L. (Asteraceae) in Korea, specifically Bidens subalternans DC. var. subalternans. This naturalized plant was discovered Geumjung-gu in Busan; Gyeongsan-si, Jillyang-eup in Gyeongbuk-do; and in Buk-gu in Daegu. Bidens subalternans var. subalternans is distinguishable from other Bidens in Korea by the following combination of characteristics: an odd-pinnate leaf, deeply lobed, narrow lanceolate, four lobes in the corolla, an oblong achene shape. This taxon is termed 'Wang-do-kka-bi-ba-neul' as a common Korean name based on its large size (in particular, the size of leaf). The key for all taxa of the genus Bidens in Korea is also provided here.

We conducted principal component analyses using the thirty two quantitative characteristics of Najas from South Korea to examine the morphological variation and diagnostic characteristics. As a result of our investigation and the morphometric analyses, each taxon could be identified using the leaf width, shape of the leaf sheath, number of teeth on the leaf margin, number of anther cells, number of areoles in each longitudinal row of seeds, and the ratio of the areole width to the length. Dioecious Najas marina was clearly distinguished from the other monoecious taxa (N. graminea, N. gracillima, N. minor, N. oguraensis, and N. orientalis) by the larger size of the stem, the leaf, the flower and the fruit. The monoecious taxa could be identified using vegetative characteristics except for N. minor and N. oguraensis, which were distinct from each other according to the locule number in the staminate flower.

An unrecorded species, Carex aequialta K$\ddot{u}$k. (Cyperaceae), was found in Yecheon-gun, Gyeongsangbuk-do and Jeju-si, Jeju-do. This species is distinguished from related taxa, C. maximowiczii Miq., C. suifunensis Kom., C. phacota Spreng., C. dimorpholepis Steud., C. shimidzensis Franch. and C. tegulata H. Lev. & Vaniot, by having suberect lateral spikes, awnless pistillate scales, short rhizomes and corymblike inflorescences. This taxon was named 'Mul-kko-ri-sa-cho' in Korean based on its external appearances and habitat. We provide its description, illustrations, photographs and the key of related taxa in Korea.

Here we report a previously unrecorded species of Korean Myriophyllum L. (Haloragaceae). This taxon, M. oguraense Miki has been regarded as a Japanese endemic for some 60 years. Myriophyllum oguraense and its closely related M. verticillatum L. share the characteristic of having pectinate emergent leaves that are similar in shape to, but much smaller than, the submerged leaves. However, the primary characteristic that differentiates these taxa is the turion shape (club shaped in M. verticillatum and linear in M. oguraense). The common name, 'Gin-dong-a-mul-su-sae-mi' was also newly given considering its characteristic turion shape. Photographs and a key to Korean Myriophyllum species are provided in addition to complete descriptions including information on nomenclatural types, distributions and specimens examined.

This study investigated the distributional pattern of meiobenthos associated with future deep-sea mining in the Korea Deep Ocean Study area present in the Clarion-Clipperton Fracture Zone (CCFZ) located in the southeastern part of the North Pacific Ocean. Standing stocks of meiobenthos were investigated in benthic impact experiment sites (BIS) and Korea Institute of Ocean Science & Technology long-term monitoring (KOMO) sites during the 2008-2014 annual field survey. A total of 14 taxa of meiobenthos were identified. Nematodes were the most abundant taxon (60-86%). Harpacticoid copepods (5-26%) and benthic foraminifera (1-12%) were also dominant at all sites. The total meiobenthic densities varied from 4 to 150 ind./10 cm2. The mean value of total meiobenthic abundance was higher at BIS than at KOMO sites, but there was no significant difference between the two sites. The mean values of the number of taxa and biomass at BIS and KOMO sites were similar. The mean abundance of nematodes that were the most dominant taxa was also higher at BIS than at KOMO sites. The standing stocks in our study sites were relatively lower than those previously reported at other CCFZ sites. These results seem to reflect a low organic concentration in the study area.
