Here we reported two unrecorded naturalized species from Korean flora. Andropogon virginicus L. of Graminaeae and Euphorbia postrata Aiton of Euphorbiaceae are collected from Dong-gu, Ulsan-si and Sinjindo-ri, Taean-gun, Chungcheongnam-do respectively. A. virginicus L. was easily distinguishable from Themeda triandras var. japonica Makino by keel on glume, 2-4 racemes and long hairy rachis. Thus, the new Korean name, 'Na-do-sol-sae', was given. E. postrata Aiton was cleary distinguished from related taxa by hairs on only edges of fruits. The new Korean name, 'Nu-un-ttang-bin-dae' was given considering the species epithet. Descriptions, illustrations and photographs showing habitat were given.

The freshwater algae were collected at reservoirs and small ponds in Gyeonggi-do and Jeju-do on June 2016. Four species of Korean previously unrecorded algae were collected in domestic fresh waters: Coelastrum rugosum, Cosmarium baccatum, Cosmarium norimbergense and Staurastrum connatum var. pseudoamericanum. The morphological characteristics of the four taxa identified in this study were showed mostly similar to the characteristics of the previously reported characteristics. However, Cosmarium baccatum was larger than the previously recorded species and Staurastrum connatum var. pseudoamericanum was wider than the previously recorded species.

We reported an unrecorded plant species, Galium bungei var. miltorrhizum (Hance) Jeong & Pak in Korea. This species is found in Gyeonggi-do, Chungcheongbuk-do, Jeollabuk-do, Gyeongsangbuk-do, and Gyeongsangnam-do. G. bungei var. miltorrhizum is distinguished from related taxa by glabrous stem and glabrous or rarely short papillate mericarps. This taxon was named 'Dung-geun-ne-ip-gal-kwi' in Korean based on shapes of leaves. We provided a description, illustrations, photographs, and a key of related taxa in Korea. And we propose a new combination (Galium bungei var. miltorrhizum).

In a survey of undiscovered taxa in Korea, three zygomycete fungal strains-EML-W31, EML-HGD1-1, and EML-RUS1-1-were isolated from freshwater, grasshopper fecal, and soil samples in Korea. On the basis of the morphological characteristics and phylogenetic analysis of internal transcribed spacer and 28S rDNA, the isolates of EML-W31, EML-HGD1-1, and EML-RUS1-1 were confirmed to be Cunninghamella bertholletiae, Cunninghamella echinulata, and Cunninghamella elegans, respectively. These species have not been previously described in Korea.

A taxonomic study was carried out to discover unrecorded species of South Korean Exetastes of which six taxa were previously known. In the present study, another six taxa were newly recognized from the country: E. adpressorius, E. allopus, E. fukuchiyamanus, E. illyricus, E. sapponensis and E. tomentosus. With the result of this study, 11 species and one subspecies in Exetastes are in total known from South Korea. In addition, a key to the South Korean species and the diagnoses and digital images of the six newly recorded species are provided.

Leuzea chinensis (S. Moore) Susanna (Asteraceae), a previously unrecorded species in Korea, was found in Yeongdeok-gun, Gyeongsangbuk-do. Symplocos nakaharae (Hayata) Masam. (Symplocaceae), which had been recorded in the literature but whose native habitat was yet to be identified, was found in Geojedo Island, Gyeongsangnam-do. It was confirmed that Epilobium parviflorum Schreb. (Onagraceae) grew naturally on the islands of Jeollanam-do. Detailed morphological descriptions and geographical distribution of the three taxa are provided.

Two unrecorded alien plants, Pilea microphylla (L.) Liebm. (Urticaceae) and Elsholtzia griffithii Hook. f. (Lamiaceae), were found in Korea. P. microphylla was discovered in Seoul-si and Jeju-do. This species is distinguished from other related Korean taxa by leaf characteristics such as spatulate or obovate shape and 2-7 mm long with entire margin. E. griffithii was discovered in Incheon-si. This species is defined by spikes, narrowly lanceolate bract with 3 mm long and relatively shorter corolla length as ca 2.5 mm. Here, we provide Korean name, descriptions of the morphological characteristics, photographs and a key to allied taxa.

Specimens donated by the late Dr. Miki, deposited in the Osaka Museum of Natural History (OSA), were examined. Among about 3,6000 specimens, 104 specimens consisting 48 taxa were from Korea. These were collected by 14 collectors, including Dr. Miki and Hyung-Doo Chang. Taxonomic comments on Korean aquatic vascular plants collection were made, especially on Ranunculus kadzusensis, Potamogeton pectinatus, Zostera japonica, Ruppia truncatifolia, and the Utricularia species, including the three unrecorded species from Korea.

More than one-hundred-twenty specimens of Basidiomycetes, Ascomycetes and slime molds were collected in Seoul National Polytechnic University Campus during the priod from June 1984 to November 1987 and examined for identity. They were classified into 25 families, 53 genera and 81 species. Among them, one genus and 2 species were confirmed as unrecorded taxa in Korea. The unrecorded genus was genus Hapalopilus and was named 'Band Dal Busut' in vernacular. The unrecorded 2 species were Hapalopilus rutilans and Hygrophorus nitratus. They were named 'No Lan Ban Dal Busut' and 'Jil San Beot Geot Busut,' respectively and their characteristics were here reported.

Algific talus slopes provide microclimates suitable for disjunct or relict populations of northern plant species at low elevation habitats in the temperate zones. The propose of this study was to assess the phytogeographical significance and produce a strategy for the comprehensive conservation of the vegetation on algific talus slopes. Therefore, we studied the floristics of bryophytes on 15 algific talus slopes in Korea. The bryophytes on the algific talus slopes in Korea consisted of 59 families, 138 genera, 226 species, two subspecies, and five varieties, totaling 233 taxa. Peculiarly, many northern bryophytes, such as Andreaea rupestris var. fauriei (Besch.) Takaki., Buxbaumia minakatae S. Okamura, Racomitrium lanuginosum (Hedw.) Brid., Hylocomium splendens (Hedw.) Schimp., and Pleurozium schreberi (Willd. ex Brid.) Mitt. were found on the algific talus slopes. Of them, unrecorded species from south Korea numbered 14 taxa and unrecorded species from the Korean peninsula numbered seven taxa. A similarity analysis based on the bryophyte flora showed that the index of similarity between regions with similar environmental factors was high. This means that the bryophyte flora composition on each algific talus slopes was affected by topography and microclimate. Algific talus slopes are phytogeographically significant microhabitats where northern plant species that advanced southward during the latest glacial age have been isolated and adapted. However, algific talus slopes have constantly been destroyed or damaged by humans without consideration of conservation. Conservation strategies to ensure the biodiversity and effective management of algific talus slopes in Korea are discussed in detail.
