Paeonia lactiflora is a valuable natural resource for horticulture and traditional Chinese medicine. To propose conservation strategy and future utility of the wild Paeonia lactiflora populations recently found around the Gyeongju National Park, genetic diversity analysis using microsatellite markers were performed. Three populations in and near the Gyeongju N.P. and one population from Jilin, China were analyzed for five microsatellite markers, producing 61 alleles with mean observed heterozygosity(
) of 0.452.

, which incorporates the allele sizes, suggested considerable differentiation between them, but without significant statistical support. STRUCTURE analysis also suggested segregation of regional populations with presence of gene flow among the three Gyeongju N.P. populations. Considering small population size and scarcity of mature individuals, further protection and long-term monitoring are needed.

During the floristic survey on Phnom Bokor National Park, Kampot, Cambodia, we encountered Balanophora fungosa var. indica, which is a tropical holoparasitic plant. To identify its host species, we collected host roots and trees nearby and tried to identify them using DNA barcoding approach. We applied plastid rbcL and matK gene regions as DNA barcode markers, and successfully amplified and sequenced the markers from 15 host roots and seven tree samples. Obtained host root sequences were identified as Primulaceae, Celastraceae, Myrtaceae, and Oleaceae, while trees nearby are Oleaceae, Myrtaceae, Sapindaceae, Rosaceae, Clusiaceae, Ericaceae, and Lauraceae. At genus level, host species are identified as Myrsine, Euonymus, Syzygium, and Olea, but failed in species discrimination. Myrsine (Primulaceae) and Olea (Oleaceae) are reported here as host species of B. fungosa var. indica for the first time. Further sampling and comparative work, and DNA barcoding will help recognize the biodiversity of the area and host species of Balanophora, together with their evolution.

Jasminum attenuatum Roxb. ex G. Don, a species of Oleaceae, was recently found in Kon Ka Kinh National Park of Vietnam that represents a new record to the flora of the country. The plant can be differentiated from its allied species J. latipetalum C.B. Clarke and J. simplicifolium subsp. funale (Decne) Kiew by the shape of its leaf blade, in having 5-20 flowered inflorescence, linear bracts, and obconic and glabrous calyx with shorter lobes. The present study provides the species description, illustrations, micrographs by scanning electron microscope of the pollen grains, and important taxonomic notes. Furthermore, a comparison of the diagnostic characters between this species and the above mentioned related species is made.

This study employed inter-simple-sequence repeat (ISSR) to assess genetic variation among 189 individuals representing 10 populations (nine in Korea and one in Japan) of Millettia japonica, which has recently been lifted from the endangered species of Korea. The calculated Shannon's information index value (I = 0.2689) of the species was appreciable and was higher than other endangered leguminous woody taxa. Gochang (I = 0.2968), Namhae (I = 0.2951), and Mt. Toham (I = 0.2823) populations showed relatively high genetic diversity, whereas the Kyushu (in Japan) population (I = 0.2487) exhibited the lowest. The results of an analysis of molecular variance indicated that 86.49% of the diversity was attributed to within populations, and 13.51% to differences among populations, suggesting that M. japonica populations do not have significant geographic differentiation and that the gene flow between populations exists to some extent (Nm = 1.8446). Continuous habitat monitoring should be conducted to conserve genetic diversity of M. japonica, particularly for those populations with relatively high genetic diversity. Selection of many individuals from the populations in Gochang, Namhae, and Mt. Toham is thought to be an appropriate strategy for ex situ conservation of M. japonica in Korea.

This study presents a survey on the bryophytes in Dongbaek-dongsan located at Seonheul Gotjawal on the north-eastern face of Mt. Halla in Jeju Island, Korea. A total of 85 taxa belonging to the Bryophyta (22 families 44 genera 62 species), Marchantiophyta (12 families 16 genera 23 species) were found. Among them, 3 moss species, Diphyscium perminutum Takaki, Racomitrium japonicum Dozy & Molk., and Isopterygium minutirameum (M
. Hal.) A. Jaeger. were new additions to the bryophyte flora of Korea. The liverwort index was 27.0%. Predominant life-form was weft. The rates for the bryophytes dominating in mesic to hygric sites were higher than for the bryophytes mainly observed in xeric habitats. We considered that the composition and distribution of species are affected by the different environmental factors according to the evergreen broad-leaved forests, wetlands and exposed spaces. Moreover, the rocks were the substrate type that play a major role in providing the micro-habitats for bryophytes in this area. Particularly, the bryophytes of swamps in this area were very unique and various for its limited space and showed plant communities with mosaic spatial pattern, along with vascular plants. We suggest more detailed and comprehensive studies on the swamps where endemic fern Mankyua chejuense B. -Y. Sun, M. H. Kim & C. H. Kim inhabits to provide valuable information for the conservation and restoration of the species and habitats.
A taxonomic study of the genus Actinidia in Korea
Kim, Yoon-Young ; Oh, Byoung-Un ;

The genus Actinidia has been recorded as having total six taxa, composed of four species and two varieties, in Korea. However, its taxonomy remains complex because of disagreement on taxonomic characters used for species boundaries. Based upon morphological, anatomical, and palynological characters, we re-evaluated species delimitations in the genus Actinidia. Critical observation of wild populations and extensive herbarium materials including types were also carried out. It is generally considered that leaf thickness and shape, hair type and color were important diagnostic characters to identify species, but these characters were insufficient to be diagnostic characters because of their wide variation ranges. On the other hands, pith pattern, winter bud protrusion rate, scale leaf number, anther color, fruit shape, and maturity season were taxonomic significance. A. arguta var. platyphylla and A. arguta var. rufinervis have been identified by hair type and color, but these characters showed continuous variation in A. arguta. Therefore, two varieties are treated as synonyms of A. arguta. Consequently four species are recognized in Korea: A. polygama, A. kolomikta, A. rufa, and A. arguta. A key is provided, as well as complete descriptions of the species examined, including information on nomenclatural types, and synonymies.
First record of Fimbristylis hookeriana Boeckeler (Cyperaceae) from Korea
Kim, Jonghwan ; Kim, Muyeol ;
Korean Journal of Plant Taxonomy, volume 43, issue 4, 2013, Pages 296~299
DOI : 10.11110/kjpt.2013.43.4.296
A newly recorded species, Fimbristylis hookeriana Boeckeler, was found in Gyema-ri, Hongnongeup, Yeonggwang-gun, Jeollanam-do and Munyeo-do Is., Gunsan-si, Jeollabuk-do, Korea. Fimbristylis hookeriana is closely related to F. dichotoma, which has ovoid spikelets, deciduous scales, pubescent culms, and short style. However, this species is distinguished by very narrowly ovoid spikelets, persistent scales, glabrous culms, and long style. We propose a new Korean name, 'Ba-Wi-Ha-Neul-Ji-Gi', meaning that this inhabits on dried rocks near seashore. Redescription, illustrations, photographs, table, and a key to species of the Fimbristylis Vahl in Korea are provided.

Subalpine species, Sorbus pohuashanensis in the Korean peninsula, which is assumed to be evolved from hybridization between S. commixta and an unknown species based on the flavonoids data. Morphometric analysis was conducted on the basis of 19 leaf and flower (or fruit) characters. A total of 721 samples in 13 populations of Sorbus pohuashanensis and S. commixta from Korea and additional specimens of S. commixta, S. pohuashanensis, and S. wilsoniana from Japan and China were examined to reveal the hybridization patterns and morphological differences. We found a preliminary evidence where Korean mountain rowan is more related to a Chinese inland taxon, S. wilsoniana, rather than Northeastern Chinese S. pohuashanensis in terms of flavonoids. The current morphological structure of the Korean mountaion rowan, however, which is more similar to S. commixta, was neither associated with that of S. wilsoniana nor that of S. pohuashanensis. This indicates that this morphological variation represents an intermediate of S. commixta and S. wilsoniana via a more ancient hybridization event in terms of qualitative characters, such as stipules, buds, and carpels. These morphometric differences together with other distinguishing characteristics suggest that the Korean mountain rowan should be considered as a conspecific species of S. commixta, although this demonstration of hybridization with the current phenetic species concept contradicts longstanding historical species concept.

Morphological characters of aggregated achenes, and achene and its epidermal microstructures were observed for 7 taxa belonging to the section Adonanthe of subgenus Adonanthe [A. amurensis Regel et Radde, A. bobroviana Sim., A. davidii Franch., A. multiflora Nishikawa et Ko. Ito, A. pseudoamurensis W. T. Wang, A. ramosa Franch. and A. tianschanica (Adolf) Lipsch. ex Bobrov] and for 1 taxon belonging to the section Lophocarpa of subgenus Adonis (A. aestivalis var. parviflora M. Bieb.). The morphological characters such as shape of aggregated achenes, length of aggregated achenes, shape of achene, and recurved type of persistent style were useful in the classification of the subgenera Adonanthe and Adonis, and each species of the series under section Adonanthe. Epidermal microstructures of achene were grouped into three types according to the presence of microwrinkles and their arranged patterns. These microwrinkles were absent in A. amurensis, were of parallel type in A. bobroviana, A. pseudoamurensis, A. ramosa, and A. aestivalis var. parviflora, and were of parallelperpendicular mixed type in A. davidii, A. multiflora, and A. tianschanica. Also, a new key to them was made using morphological characters of their aggregated achenes and achene.

Records found on labels of specimens deposited at Kyoto University (KYO) and references about three Japanese taxonomists, Koidzumi, Gen'ichi (1883-1953), Ohwi, Jisaburo (1905-1977), Kitamura, Siro (1906-2002) were assembled to produce collector's itineraries from 1930 to 1935 in Korea. The quality of data on labels of the specimens varies, but most are only the collector's name and country of collection, often, the locality data are only textual, and the Chinese and Japanese names, as well as the ethnic dialects common to the region, varies widely. It is estimated that approximately 2,000 specimens collected from Korea by three taxonomists are currently held within the collections of Kyoto University herbarium (KYO). Koidzumi, who was the professor of Kyoto University, traversed different northern parts of the country, such as Island Jeju-do, Mt. Keumkang-san, Hamkyongbuk-do during summer (July to August) in 1932, 1933, and 1935. In 1930 and 1932, Ohwi spend three months in the unexplored mountains in northern parts, such as Hamkyeongnam-do, Hamkyeongbuk-do, and Gangwon-do. On the other hand, for two months in the middle of 1935 visited Jeju-do, Mt. Jirisan and travelled through southern parts. Unlike two previous botanists, major collections in Korea by Kitamura took place twice in one major area in northern part and Jeju-do and Mt. Keumgang-san in 1930, 1932, and 1935.
