  • Larvae of fishes were collected at 26 stations in the Korea Strait, by horizontal towings using the fish larval net (Norpac) in the surface layer and by oblique towings using Isaac-Kid mid-water trawl in the mid-water layer in summer (July) and in autumn (November), in 1983. The towing speed was 1.5 knots. Of the larval fish examined, 3,529 individuals were identified to generic and specific levels. They belong to 27 families, consisting of 38 species in 37 genera. Unidentified were 114 specimens. The most abundant species was Engraulis japonica which occupied $88.5\%$ of the whole 3,645 individuals. Diaphus sp. took the second place with 50 individuals ($l.3\%$). Seasonally abundant species were in the order of Engraulis japonica, a Gobid, Trichiurus lepturus, and Diaphus sp. in summer, and in the order of Diaphus sp., Engraxlis japonica, Bothus sp., and a Ophichthid in autumn. Of these larvae, Engraulis japonica and Diaphus sp. continuously appeared from summer to Autumn. Champsodon sp., Diaphus sp. and Synagrops philippinensis were unrecorded species in Korea.

  • Two unrecorded naturalized species, Lolium rigidum Gaudin (Poaceae) and Oenothera rosea L'H$\acute{e}$r. ex Aiton (Onagraceae) were newly reported in Korea. L. rigidum, 'Daeng-Dol-Bo-Ri', was found at roadside of Yesong beach, Yesong-ri, Bogil-myeon, and roadside of Myeongsasimni beach, Sin-ri, Sinji-myeon, in Wando-gun, Jeollanam-do. It was distinguished from L. mutiflorum Lam by spikelet 10-20 mm long, florets 2-10(-13), and obtuse lemma, awn absent or up to 3-8(-10) mm. O. rosea, 'Ae-Ki-Bun-Hong-Nat-Dal-Mat-I-Kkot', was found in side of Wondong wetland, Yongdang-ri, Wondong-myeon, Yangsan-si, Gyeongsangnam-do. This taxon was distinguishable from other Oenothera in Korea by following combination of characters, stem erect to ascending, petal 5-12 mm long, pink to bright purple. Descriptions and illustrations of the two taxa and their photographs in the habitat are provided along with a key to the species of Lolium and Oenothera from Korea.

  • Since a new (unrecorded) species was reported in 2016, a total of four sea snake species are currently listed in Korean waters. Although the possibility of year-round inhabitation of sea snakes in Korean waters has increased due to climate change, the related studies are scarce because of the lack of human resources and available equipment. We placed posters and banners requesting voluntary information on sea snakes in coastal regions and Jeju Island to obtain information on sea snake distributions in the coasts of South Korea and possible specimens through volunteer activities. As a result, we received total 45 reliable reports, including photographs or video, between March 2013 and December 2016. Eighteen reports on three sea snake species and thirteen capture cases of two species were submitted from Jeju Island and southern coastal regions of Korea mostly between August and November. There were twenty-seven false reports including seven cases of terrestrial snakes, eighteen fishes, and one each of invertebrate and inanimate material. Based on the results, we proposed the effective way of sea snake surveys using volunteers.

  • Two unrecorded naturalized species, Stachys agraria Schltdl. & Cham. and Dracocephalum moldavica L (Lamiaceae), are newly reported in Korea. Stachys agraria and D. moldavica were found at Seogwipo-si on Jeju-do and at ChunChen-si in Gangwondo in Korea, respectively. Stachys agraria is distinguished from other related Korean taxa by corolla of 2.4-5.2 mm long with six to twelve flowers in the node. Its local name is "Ae-gi-seok-jam-pul" based on shorter than longer corollar. Dracocephalum moldavica was distinguishable from other Dracocephalum in Korea by the following combination of characters, oblong to ovate-triangular ($1.7-2.4cm{\times}0.8-1.2cm$) leaves and rough crenate at the margin. This taxon is referred to as 'Hyang-yong-meo-ri' in Korean based on its fragrance. We provide a description, illustrations, photographs, and a key of related taxa in Korea.

  • Since the establishment of the Korean Society of Plant Taxonomists (KSPT) on Dec. 13, 1968, the professional manpower training and research activities have been analyzed. The survey method was based on the homepage of the KSPT and the Korean J. Pl. Taxon, and on data provided by each university about professional manpower. Over the past 50 years, a total of 680 specialists in plant taxonomy have been trained, consisting of 537 master's degree holders (274 males, 263 females) from 30 universities and 143 PhDs (97 males, 46 females) from 26 universities, and the number has increased significantly since 1998. With regard to changes in the field of research over the last ten years, revision papers were the most common in the period of 1988-1997 (72%), but this rate has decreased to 51% over the last ten years, while the number of unrecorded papers has increased to 28%. In the 629 revision papers on taxa, 49% of the taxa belong to Asteraceae, Ranunculaceae, Cyperaceae, Liliaceae, Rosaceae, Fabaceae, Apiaceae, Lamiaceae, Orchidaceae, Oleaceae, Euphorbiaceae, Polygonaceae, and Amaryllidaceae. With regard to changes in research methods, the number of morphological papers increased from 6% to 51%, while pollen papers have decreased from a rate of 20% to only 2%. Chromosome studies account for 3-4%, chemotaxonomic studies 2%, and DNA studies remain low at 3-16%. The percentage of papers in English now stands at 43%, mainly due to the increased number of papers on unrecorded species.

  • This study presents a comprehensive account of the flora of hydrophytes and hygrophytes on Jeju Island. This approach aims to contribute to fundamental information about the conservation of plant diversity in wetlands. Field surveys were carried out from May of 2010 to September of 2014 in various types of wetlands on Jeju Island. A total of 189 taxa, including 52 families, 98 genera, 181 species, 6 varieties, 2 forma and 189 taxa, were found. Among them, 99 taxa (38 families, 60 genera, 96 species and 3 varieties) were hydrophytes and 90 taxa (23 families, 45 genera, 85 species, 3 varieties and 2 forma) were hygrophytes. In addition, Eleocharis${\times}$yezoensis H. Hara (Cyperaceae) was newly added to the flora of Korea. The protected wild plants designated by the Ministry of the Environment were 5 taxa, including Brasenia schreberi J. F. Gmel. and Dysophylla yatabeana Makino. The endangered species found included one Critically Endangered Species (i.e., Mankyua chejuense B.-Y. Sun, M. H. Kim & C. H. Kim), 5 Endangered Species (e.g., Lysimachia leucantha Miq.) and 7 Vulnerable Species (e.g., Tillaea aquatica L.). The floristic regional indicator plants found in this area were 44 taxa comprising 10 taxa of grade V, 7 taxa grade IV, 15 taxa of grade III, 5 taxa of grade II, and 7 taxa of grade I. The identified naturalized plants were 10 taxa; 8 families, 8 genera, 9 species and 1 variety. In the wetlands on Jeju Island, high plant species diversity was shown, and a number of rare plants and phytogeographically important plants were found. For these reasons, we consider that the wetlands on Jeju Island are very important areas from a botanical point of view. It is necessary to establish specific protection and maintenance policies in an effort to conserve these wetlands and species.

  • Two naturalized plants belonging to Plantaginaceae and Labiatae are newly recorded for Korean flora. Nuttallanthus canadensis (L.) D. A. Sutton, a taxon of the unrecorded genus Nuttallanthus (Plantaginaceae), was founded in Seogwipo-si, Jeju-do. This species can be distinguished from the Linaria species by its corolla with a pale blue to a pale purple color, a lower lip longer than the upper lip and seed with 4-7 angles when cross-sectioned. Lamium purpureum var. hybridum (Vill.) Vill. was found in Gwangju Metropolitan city, Jeongeup-si, Jeollabuk-do and Gochang-gun, Jeollanam-do. It can be distinguished from L. purpureum L. by its irregularly dentate bracts and upper lips 3-4 mm in length. New Korean names were given, as Sol-lip-hae-rancho to Nuttallanthus canadensis (L.) D. A. Sutton and Eu-reop-gwang-dae-na-mul to Lamium purpureum var. hybridum (Vill.) Vill. In addition, their descriptions, photos, illustrations and keys to related genera and species are provided here.

  • We found Diplachne fusca subsp. uninervia (J. Presl) P.M. Peterson & N. Snow, an unrecorded alien plant, in Gimpo-si, Gyeonggi-do and Ganghwa-gun, Incheon Metropolitan City. Diplachne fusca subsp. uninervia is native to North America (the USA and Mexico), Central America (Belize, Costa Rica, Honduras, and Nicaragua), the Caribbean (the Bahamas, Cuba, Jamaica, and Puerto Rico), and South America (Venezuela, Brazil, Bolivia, Ecuador, Peru, Argentina, Chile, Paraguay, and Uruguay). It is reported as an invasive species worldwide. Diplachne fusca subsp. uninervia is closely related to D. fusca subsp. fascicularis (Lam.) P.M. Peterson & N. Snow (Gaet-deu-reong-sae in Korean), an invasive species in Korea, and both are infraspecific taxa of the species D. fusca. Diplachne fusca subsp. uninervia is distinguished from D. fusca subsp. fascicularis by the small size of its spikelets, glumes, and lemmas, with apex awnless. Its common name is "Jom-gaet-deu-reong-sae" based on the short spikelets. We found that D. fusca (≡Leptochloa fusca), previously known as "Gaet-deu-reong-sae", was misapplied. It is morphologically different from D. fusca subsp. fascicularis. Therefore, we changed the scientific name of Gaet-deu-reong-sae from D. fusca (≡L. fusca) to D. fusca subsp. fascicularis based on the type specimens, original descriptions, and recent studies.
