Nervilia nipponica Makino (Orchidaceae), a genus and species previously unrecorded for the Korean flora, was collected in the deciduous forests of Mt. Halla, Jeju Island. This species was known to be distributed mainly from tropical to subtropical regions of Taiwan and Japan. Genus Nervilia is distinguished from other genera of tribe Nervilieae (Orchidaceae) by having only a single, plicate leaf which develops and senesces before flowering shoots appear, stems unbranched, two pollinia, and sometimes lacking a viscidium.

To find unrecorded diatom species in the Nakdong River Estuary and Yeongil Bay, bottom sediments in the estuary, and seagrasses in the bay were collected from 12 sampling sites. Eighteen species and four genera are added to the national flora of diatom as newly recorded one. In the Nakdong River Estuary, twelve species are new records to Korea, Martyana atomus (Hustedt) Snoeijs, Pseudostaurosira perminuta (Grunow) Sabbe & Vyverman, Trachysphenia acuminata M. Peragallo, Trachysphenia australis Petit, Fallacia clipeiformis ($K{\ddot{o}}nig$) D.G. Mann, Amphora graeffeana Hendey, Amphora jostesorum Witkowski, Metzeltin & Lange-Bertalot, Amphora ostrearia var. vitrea (Cleve) Cleve, Amphora wisei (Salah) Simonsen, Halamphora eunotia (Cleve) Levkov, Halamphora lineata (Gregory) Levkov, Nitzschia littorea Grunow. In Yeongil Bay, four species are added as new, Licmophora gracilis var. anglica ($K{\ddot{u}}tzing$) H. Peragallo & M. Peragallo, Tabularia investiens (W. Smith) Williams & Round, Nitzschia composita Giffen, Nagumoea neritica Witkowski & Kociolek. Two species occurred simultaneously in both regions, Fragilaria cassubica Witkowski & Lange-Bertalot and Hyalinella lateripunctata Witkowski et al.

A recently published Korean Flora, "The genera of vascular plants of Korea (GFK)", includes the descriptions and keys for 217 families, 1,044 genera, and 3,209 species of Korean vascular plants. We reclassified these taxa according to the recent APG classification system, which resulted in 64 orders, 204 families, 1,044 genera and 3,209 species. Twenty-two families from the GFK were abandoned because of changes to the familial delimitations in the APG system. In contrast, the number of families in the Liliaceous group was increased. The Liliaceae in the GFK included 31 genera and 109 species. These taxa are now assigned to 10 families in four different orders including Liliales, Asparagales, Alismatales, and Dioscoreales because of the drastic changes to the monocot classification system in the past 20 years. In addition, the family name of the Aucubaceae was changed to Garryaceae. As a result, the number of families in the GFK has been reduced to 204. The results were summarized in four tables and two figures at the levels of unofficial higher taxonomic hierarchies, orders, families and genera. This new information can provide a guidelines for selecting the phylogenetic analysis unit for the Korean tree of life (KTOL) project. Futhermore, the updated classification system also provides an important summarization for the systematic community for placing the Korean flora in a modern phylogenetic context.

The current surveys of Ulva in the subtidal area around Jeju Island give a chance to discover unrecorded green algal species of the Korean macroalgal flora. As a result of this investigation, we found Ulva adhaerens Matusmoto & Shimada, inhabiting the subtidal regions, up to 15 m deep, and conducted the DNA barcoding on plastid rbcL-3P and tufA regions with describing the morphological characteristics. Our specimens of U. adhaerens forms a monophyletic clade with the Japanese type specimen and U. piritoka Ngāti Kuri, Heesch & W.A. Nelson from New Zealand exhibiting each 0.3% sequence divergences, respectively, in the plastid rbcL-3P. The genetic variation of U. adhaerens clade is 1.0-3.9% in rbcL-3P and 4.8-9.8% in tufA to each Ulva species, including the generic type, U. lactuca Linneaus. The morphology of Korean U. adhaerens specimens is identical to the type specimens of U. adhaerens from Japan having the development of rhizoidal filaments from both of the cell layers of the distromatic blade and the extension of rhizoidal clumps with adhesive trait between blades by extended rhizoidal clumps at the basal blades. The thallus attachment to substrate is by numerous minute discoidal plates made up of rhizoids originating from the inner part of distromatic blades in basal. Although there are still some problems to resolve the relationship between U. adhaerens and U. piritoka in the rbcL dataset and the phylogenetic pattern of the Group II intron of rbcL, we propose the new record of U. adhaerens in Korean macroalgal flora based on the morphological characteristics of Korean specimens. Continued study of the genus Ulva by morphological and molecular assessment will delimit the species of Ulva, elucidate the relationships between them, and uncover the species diversity.

Detailed descriptions of five species of the lichen genus Canoparmelia Elix & Hale. are presented. Until now, three species of the genus Canoparmelia, including C. apata (Krempelh.) Elix & Hale, C. owariensis (Asah.) Elix, and C. texana (Tuck.) Elix & Hale have been reported in South Korea. Canoparmelia carneopruinata (Zahlbr.) Elix & Hale, C. crozalsiana (de Lesd.) Elix & Hale, and C. ecaperata (M$\ddot{u}$ll. Arg.) Elix & Hale are new to the South Korean lichen flora. An artificial key is provided for all species of Canoparmelia, including the three new records.

Two species of the Korean Agaricales are described and illustrated in this paper. Two genera Cystoagaricus and Limacella are new to Korean agaric flora. All of these, Cystoagaricus strobilomyces and Limacella glioderma are recorded for the first time in the Korean fungus flora. The collections cited are all preserved in the Herbarium Conservation Center of National Academy of Agricultural Sciences.

Three species of the Laboubeniales from Korea are described. They are new to the mycological flora of Korea. Corethromyces purpurascens on several parts of Ochthephilum densipenne, Laboulbenia barbara on the metasternum of Philonthus longicornis and L. compressa on the elytra of Harpalus tinctulus were found.

A recent rise in mean global temperatures suggests a shift in the temporal cycles of natural seasons. The impacts of warming trends can alter the temporal and spatial distribution of flora and fauna. Especially, phenological cycles are very sensitive to the occurrence of alternation of hot and cold seasons. Phenological calendars reflect the natural seasonality. In more detail, phenological cycles affects agriculture and human health (i.e. the amount of fruit production and allergies), as well as tourism industries like flower fairs or festivals. (omitted)
