In this study, we report a new record of the clustered bur-reed Sparganium glomeratum (Laest. ex Beurl.) Beurl., from Yongneup Moor of Daeamsan Mt. in Gangwon-do, Korea. This species is distributed in the cool temperate and circumboreal regions of the Northern Hemisphere. As we recorded this species in a high-altitude wetland, we named it "Du-me-heuk-sam-neung" after the Korean word that translates to "Sparganium found in deep mountains." We provide descriptions of the morphological characteristics, photographs, and detailed illustrations of S. glomeratum, as well as a key to allied taxa in Korea.

Sparganium coreanum, a barely recognized species in Korea, was rediscovered during a field survey by the authors, who conducted a re-examination of specimens deposited in the Herbarium of the Korea National Arboretum (KH). This species was described initially by H. $L{\acute{e}}veill{\acute{e}}$ from a specimen collected by F. Taquet from Jeju-do (Taquet 2150). Subsequently, however, it was overlooked and unrecognized among South Korean flora. Several populations of S. coreanum were found in the southern part of the Korean Peninsula and on Jeju-do, although it has long been recognized as S. erectum owing to certain vegetative morphological characteristics shared between the two species, such as robust stems, a similar plant height, and globose rhizomes. However, it is distinct from S. erectum by the number of female heads on the lowest inflorescence branch and the size and shape of the fruit. In this study, we provide a detailed description, illustrations, and photographs with a revised taxonomic key for identification of Sparganium species in Korea.

Pollen analysis on a 320cm core collected from paengsung area (36°56′50"N, 127°03′10"E) in southwesterm korea was carried out to investigate the changes in past climate and vegetation in that area. In this research it was found that pollen zones are divided into two layers of substage IIb and IIc. Pollen zone IIb, the lower layer, was dominated by high percentages of deciduous broadleaved trees such as alnus, Quercus, Corylus, Betula, Carpinus and Salix. Trapa, Typhaceae and Nymphaceae growing in wet habitat and Chenpodiaceae were pornounced amont the nonrboreal pollens. At that time, it seems that it was warmer and more humid than present. In pollen zone IIc, the upper layer, pollen of Pinun was dominant and those of Artemisia, Gramineae, Compositae, Cyperaceae and spore increased while of Quercus, Betula and Nymphaceae decreased. It is supposed that the climate of this zone was drier that the lower laywer.

Three different species of cattails (Typha orientalis, Typha angustata, Typha latifolia) cultivated in South Korea were examined as raw materials for the production of pulp and paper. Soda pulping with anthraquinone was used for the stems and the leaves of cattail, separately. Addition of anthraquinone in soda pulping improved the yield greatly. Chemical components between three cattail species and within each species (leaves and stem) gave little differences. Average fiber length of the bleached cattail fibers was a little shorter than that of the HwBKP of Eucalyptus. Average fiber width of the cattail fibers was a half of that of the HwBKP. Compared to the HwBKP, cattail pulp gave higher breaking length, higher opacity, and better smoothness at equivalent freeness.

This paper deals with pollen analysis of a 190cm core collected from the Chollipo Arboretum sedimentary basin($N36^{\circ}47$ 43", $E1269^{\circ}$ 7") in southwestern Korea in order to know the change of the climate and vegetation. In this research it is found that the pollen zones are divided into two layers. Pollen zone, I, the lower layer, is flourished with broadleaved trees such as Quercus, Alnus, Corylus, Betula, Carpinus and Castanopsis, and about 30~40% of pollen of those trees consist of that of Q. acuta/glauca and Castanopsis which are evergreen trees. And pollen of Trapa, Typhaceae and Nymphaceae living in wet habitat, is dominant among the nonarboreal pollen. Therefore we can conclude that it ould be warmer and more humid than present in this area of the past. In pollen zone, the upper layer, pollen of Pinus is dominant and those of Artemisia, Gramineae, Compositae and spore are increased in quantity, while pollen of Quercus, Belula and Nymphaceae decreased. It it supposed that the climate of this zone was drier than that zone.that zone.

Two unrecognized species of Sparganium of Korea were found during the our field expeditions and phylogenetic analyses of specimens deposited in the Herbarium of Korea National Arboretum (KH). S. coreanum H. $L{\acute{e}}v$. was first reported as a new species based on the specimen (Taquet, 2150) collected from Jeju Island. It has been recognized as synonym or infraspecific taxa of S. stoloniferum and S. eurycarpum or even never recognized recently. However, phylogenetic tree showed that S. coreanum is monophyletic and has sister relationship with S. eurycarpum. Furthermore, additional distribution localities were also found by herbarium survey. Morphological characteristics and distribution information of S. coreanum will be discussed. Another Sparganium species found from Mt. Daeam is occurring either as floating or emergent. Although we could not identify this species since lack of any flowers or fruits for two year surveys, phylogenetic analyses results showed that this species belong to the clade of S. glomeratum, which is distributed in high elevation lakes and marshes of Europe, Asia, and North America. Additional survey of morphology and report will be needed.

Pollen analysis of moor peat of Daeam Mountain revealed vegetational history around Daeam Mountain. The pollen stratigraphy might be zoned into three, Zone I, Zone II and Zone III for the past 2, 200 years. The time required for amount of the accumulated peat in the moor was estimated in terms of the balance of the accumulation and decay of organic carbon of the deposit peat. Zone I(770~2, 200 yr BP) had Pinus and Quercus as main elements. Gramineae decreased while Typhaceae, Cyperaceae and spores such as Polypodiaceae increased. Zone II(300~770 yr BP) showed warming trend which is suggested by high pollen concentrations of Quercus, Juglans, Carpinus, Ulmus and by a more diverse flora of deciduous borad-leaved trees than Zone I. Pinus decreased in this zone. It suggests that the overall environment became milder than Zones I and III. Zone III(earlier than 300 yt BP) was predominantly Quercu and Pinus with amount of nonarboreal species such as Artemisia, Gramineae and Chenopodiaceae, that was grown under dry conditions. It suggests that overall environment vecome humid by comparison with the present time and it is surmised the course of boggy ground formation by a retrogressive succession.

Genus Typha L. (Typhaceae; Cattail in common) is one of the hydrophytic plants found in semi-aquatic regions. About nine to 18 species of the genus exist all over the world. In Korea, the most commonly found cattail species are T. laxmanni and T. angustifolia. The aim of this study was to prepare a cDNA library and sequences and analyze expressed sequence tags (ESTs) from these species, T. laxmanni and T. angustifolia. In the case of T. laxmanni, we observed that 715 out of 742 ESTs had high quality sequences, whereas the remaining 27 ESTs were low quality sequences. In this study, we identified 77 contigs, 393 unassembled clones and 65.7% singletons. Furthermore, in the case of T. angustifolia, we recorded 992 high quality EST sequences, and by excluding 28 low quality sequences from among them, we retrieved 120 contigs, 348 unassembled clones and 48.9% singletons. The basic local alignment search tool (BLAST) and Kyoto encyclopedia of genes and genomes (KEGG) database results enabled us to identify the functional categories, i.e., molecular function (16.5%), biological process (22.2%) and cellular components (61.3%). In addition, between these two species, the no hits and anonymous genes were 4.2% and 11.7% and 6.2% and 11.2% in T. laxmanni and T. angustifolia, respectively, based on the BLAST results. The study concluded that they have certain species-specific genes. Hence, the results of this study on these two species could be a valuable resource for further studies.
