The newly recorded species, Diplazium mettenianum (Miq.) C. Chr. var. mettenianum (Athyriaceae) was collected from a forest in Min-oreum, Jeju-do. D. mettenianum var. mettenianum (vernacular name: 'Kit-ju-reum-go-sa-ri') is distinguished from other Korean congeners of the genus Diplazium by having pinnae shallowly or halfway lobed, lower pinnae stalked, lanceolate, pinna segments serrate margin and obtuse apex. A new Korean name, 'Kit-ju-reum-go-sa-ri', was given based on the shape of pinna halfway lobed. Descriptions and illustrations of this taxon and its photograph in the habitat are provided along with a key to the species of Diplazium from Korea.

This study aimed to elucidate the distribution of vascular plants in Namhansanseong (Gwangju-si, Gyeonggi-do), Korea. The results of 30 field surveys from June 2019 to June 2020 identified 568 total taxa, representing 513 species, 10 subspecies, 40 varieties, 3 forms, and 2 hybrids in 335 genera and 107 families. Among them, 17 taxa were endemic plants to Korea, and one taxon were endangered plant and three taxa were red list plants. The floristic target plants amounted to 63 taxa, specifically one taxon of grade V, seven taxa of grade IV, 12 taxa of grade III, 14 taxa of grade II, and 29 taxa of grade I. And 66 taxa were northern lineage plants. Alien plants were recorded a total of 61 taxa with a Naturalized Index of 10.7%, the Urbanization Index was calculated to be 9.8%. As the result of comparison with previous studies, in this study a total of 213 taxa were newly identified representing 187 species, three subspecies, 19 varieties, one form, and two hybrids in 161 genera and 66 families.

Surveys on Jeju-do (Quelpart Isl.) unearthed about 40 earthworm species or sub-species. Several considered new to science are described. Only a dozen were previously known and these are taxonomically reviewed. The two most commonly recorded in surveys by S. Kobayashi in the 1930s were Drawida anchingiana Chen, 1933 and Metaphire quelparta (Kobayashi, 1937), neither recently relocated. Morphologically similar taxa, supported with DNA barcodes, for Moniligastridae, are Drawida anchingiana seogwipo, D. anchingiana halla and D. iucn spp. or sub-spp. nov. For Megascolecidae, new taxa and synonyms are: Amynthas arx and A. aucklandis spp. nov. that have seminal grooves rather than the eversible male pores of Metaphire plus Amynthas simplex is another new species. Amynthas sangumburi Hong & Kim, 2002 is recognized as a probable new synonym within the A. corticis (Kinberg, 1867) species-group while Amynthas corticis saeseum sub-sp nov. is described. Amynthas gracilis (Kinberg, 1867) is a new record from Jeju and Korea (with A. bouchei, A. omodeoi and A. edwardsi all by Zhao & Qiu, 2009 possible synonyms of this species group from China) with a Jejuan sub-species, A. gracilis insularum, sub-sp. nov. Presence on Jeju of Amynthas carnosus (Goto & Hatai, 1899) is confirmed (its further new synonyms are Chinese A. fuscus Qiu & Sun, 2012 and A. taiwumontis Shen et al., 2013), as is A. micronarius (Goto & Hatai, 1898) (with new synonym A. montanus Qiu & Sun, 2012 also an invalid secondary homonym). Amynthas phaselus maculosus (Hatai, 1930) is in new combination with A. kamitai (Kobayashi, 1934) and A. minjae Hong, 2001 syns. nov. Two newly described Metaphire quelparta sub-spp are M. q. seogwipo and M. q. valhalla these being supported with DNA barcodes despite the nominal taxon not yet being confirmed.

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.
