This study was carried out in order to catalogue the folk plants of 7 counties and cities of northern region of Chungcheongbuk-do from March to October, 2011. Based on the 626 survey sheets collected from 67 residents at 17 places of 7 counties and were subsequently analysed. The identified folk plants in the northern region of Chungcheongbuk-do consisted of a total 348 taxa; 98 families, 250 genera, 298 species, 5 subspecies, 38 varieties, and 7 forms. The use by its usage were: 223 taxa; edible, 123 taxa; medicinal, 4 taxa; dye, 2 taxa; aroma, 6 taxa; spice, 32 taxa; ornamental, 11 taxa; oil, 4 taxa; starch, 22 taxa; and others, respectively, so the edible use is the highest. The most useful part was the leaf, followed by fruit and root. The consistency comparison between the scientific and the local name were the highest in the 50's and the lowest in 80's.

The diversity of the genus Megacollybia in Korea was examined based on morphological observation and analysis of molecular data. Currently, the genus is consisted of nine species with a global distribution. However, only M. platyphylla has been reported in the floral survey of Korea. During our re-evaluation of the taxonomic diversity of Megacollybia in Korea, six Megacollybia specimens collected in 2012 were identified based on internal transcribed spacer (ITS) sequences and morphology. Here, we report two Megacollybia species, M. clitocyboidea and M. marginata, as newly recorded species from Korea. The microscopic features of the two species are provided in this study. To our knowledge, this is the first phylogenetic analysis of Korean Megacollybia species.

Rhododendron keiskei Miq. var. hypoglaucum Suto & Suzuki (Ericaceae) was found in Yeosu-si, Jeollanam-do, Korea. This species is distinguished from related taxa in Korea by lepidote hairs entire, flower-bud terminal, inflorescences umbel-like racemes, corolla lepidot outside, white tinged with yellow. This taxon was named 'Seom-Jin-Dal-Lae' in Korean based on its habitat. We provide its description, illustrations, photographs and a key of related taxa in Korea.

Carex kamagariensis K. Okamoto was found in throughout the nation. This species is distinguished from other related taxa in Carex sect. Mitratae by pistillate scales with a long arista and achenes constricted above in the middle. A new Korean name, 'Jom-mok-po-sa-cho', is based on its small size and floral character similarity to C. genkaiensis. In this study, a description, illustrations and habitat photos of the species are provided. The key of its related species is also provided.

Despite poorly documented species delimitation and unresolved taxonomic nomenclature, four species of Symplocos (S. coreana, S purnifolia, S sawafutagi, and S. tanakana) have been described in Korea. In this study, we carried a comparative wood anatomy analysis of all four species of Korean Symplocos to understand the wood anatomical variations among them. The results of this study indicated that Korean Symplocos are comparatively indistinguishable in terms of their qualitative wood features, except for exclusively uniseriate rays present in S. purnifolia instead of uniseriate to multiseriate in other three species. Nevertheless, differences are noticed in quantitative wood variables such as the vessel density, vessel size, and ray density. The vessel density of S. purnifolia is more than twice as high as those of S. sawafutagi and S. tanakana. In contrast, the vessel circumference and diameter on both plants of S. sawafutagi and S. tanakana is nearly twice as large as those of S. purnifolia. Symplocos coreana has characteristic intermediacy between these two groups in terms of vessel features and is closer to S. purnifolia in terms of its ray density level. A cluster analysis based on a paired group (unweighted pair-group method with the arithmetic mean, UPGMA) algorithm using the Euclidean similarity index clearly differentiates S. purnifolia from the remaining species, representing the first branch of the phenogram.

Two alien plants Holosteum umbellatum L. and Asperugo procumbens L., belonging to Boraginaceae and Caryophyllaceae, respectively, have been first recorded in Hongseong-gun, Chungcheongnam-do and Incheon, South Korea. This initial investigation reports to inform the importance of detection and extermination of these potential weeds in surrounding areas. Furthermore, we report the morphological characteristic features of these two alien plants.

An unrecorded Orchid species, Habenaria dentata (Sw.) Schltr. (Orchidaceae), was recognized in Gahoe-myeon and Ssangchaek-myeon, Hapcheon-gun, Gyeongsangnam-do, South Korea. H. dentata is closely related to H. radiata (Thunb.) Spreng., it can distinguished by sepal white and larger than petals, and serrated margins of the labellum. A new Korean name, 'Keun-hae-o-ra-bi-nan-cho', was given based on its taller stem and more flowers (at least with three) in comparison to H. radiata (Thunb.) Spreng. We provide here its redescription, illustrations, photographs, and a key to its closely related taxa.

The purpose of this research is to valuate the economic value of the arboretum which will be provided in Multifunctional Administrative City by estimating citizens' willingness to pay with double-bounded dichotomous choice contingent valuation method, and to provide the basic information necessary for designing and managing it for the future by identifying the types of the variables affecting the WTP. It was found that respondent's average WTP for arboretum was \23,508, and when this figures applied to all the Seoul citizens aged between 20 and 59, the economic value of it was \157,000,000,000. The variables affecting the amount of WTP were visit intention, variety seeking tendency, level of income and environmental attitude. However, environmental attitude negatively affected the amount of WTP. Average WTP for the entrance fee was \5,090, and both variety seeking tendency and visit intention were influencing factor affecting the amount of WTP. Respondents were taking charging entrance fee for granted because most of arboretums are commercial. It can be expected that much of maintenance cost will be covered from the entrance fee.

We collected nearly 70 specimens of Amanita species during a diversity study of Korean mushrooms conducted in 2012. In this study, we primarily investigated 23 Amanita specimens belonging to sections Amanita and Vaginatae. Based on sequence data of the internal transcribed spacers and partial large subunit of ribosomal RNA and morphological characteristics, we identified the following 15 phylogenetic species: A. alboflavescens, A. ceciliae, A. farinosa, A. fulva, A. griseofolia, A. ibotengutake, A. melleiceps, A. orientifulva, A. pantherina, A. rubrovolvata, A. sinensis, A. subglobosa, A. vaginata, A. cf. vaginata f. alba, and an undescribed Amanita species. In this study, four of the identified Amanita species (A. griseofolia, A. ibotengutake, A. orientifulva, and A. sinensis) were reported for the first time in Korea.

We report a taxon of the unrecorded genus Knorringia (Polygonaceae) from Baengryeongdo, Ongin-gun, Incheon-si in the Korean peninsula. This taxon is K. sibirica (Laxm.) Tzvelev subsp. sibirica., has been known from Siberia, Mongolia and China. The new Korean name, 'Si-be-ri-a-yeo-kkwi', was given considering the species epithet and the type locality, Siberia. Description, illustration and photograph showing habitat were given.
