Most evergreen Quercus species are typical, dominant members of Korean evergreen forests. However, little is known about the distribution status of Q. myrsinifolia Blume there. To enhance our knowledge about their natural range in Korea, we conducted field surveys based on specimen records and an extensive literature search. We also determined their exact number as a first step in planning their conservation. The results indicated that these trees are strictly limited to Jin Island, and 169 mature individuals were the maximum number and occurred in only three subpopulations on that island. Previous misidentifications and perhaps mislabeled locations for plant specimens were the main reasons for earlier confusion about distribution. We believe that these results can provide guidance when making specific recommendations for management interventions. These discoveries also demonstrate the value in having reliable information about plant specimens in general. We also speculated about what makes this species particularly vulnerable to local extinction.

A new species, Pseudostellaria baekdusanensis M. Kim (Caryophyllaceae), has been named and described from Mt. Baekdu of the Korean peninsula. Pseudostellaria baekdusanensis shares several characteristics (same size leaves, axillary or terminal flowers, emaginate petals, etc.) with its related species P. japonica (Korshinsky) Pax. It is, however, distinct from P. japonica which have large plant (25-35 cm), leaf blade margins and midveins with long hairs, shallow emaginate petal apex, (2) 3 styles, and cleistogamic flowers by having small plants (9-13 cm), leaf blade basal margins with long hairs, deep emaginate petal apex, 2 styles, and non-cleistogamic flowers.

A new speices, Potentilla gageodoensis M. Kim found in Is. Gageodo, Jeollanamdo Province, Korea, is firstly named and described. This species is similar to its related species P. fragarioides in having several characteristics like pinnately compound leaves, pubescent leaf blades and leaf petioles, different leaflets size, absent stolons, etc., but is distinct from P. fragarioides which has thin leaf textures, 7-13 leaflets, elliptic terminal leaflets, small petal size, and ciliate leaflet margin by having thick leaf textures, 5 leaflets, broadly ovate terminal leaflets, large petal size, and densely white ciliate leaflet margin.

We report a new record of Jasminum albicalyx Kobuski in Vietnam. The plant differs from J. pedunculatum Gagnep., a closely related taxon, by foliar and floral characters such as less number of lateral veins, presence of domatia at vein axils on the abaxial surface of leaf, smaller bracts, white calyx having more number of lobes and less number of lobes in corolla. Morphological description, line drawing and color photographs are provided in addition to the species key of allied species of Jasminum albicalyx in Vietnam.

The taxonomic status of a new forma, Opuntia humifusa (Raf.) Raf. f. jeollaensis E. J. Kim & S. S. Whang, and the taxonomic relationships of three Korean cladodes were studied based on DNA sequences of three genes. The new forma O. humifusa f. jeollaensis (Wanggasi-Chunnyuncho) is simlilar to O. humifusa (Chunnyuncho), but differ in having both flower with the reddish inner center, and strong and many 3 cm long spines. Molecular studies showed that the new forma grouped into Macrocentra series instead of Humifusa series which included Korean O. humifusa. We designated the new taxa firstly studied here as a new forma, because the taxa have been mainly cultivated in farmlands in Jeolla-do area rather than distributed in nature. The taxonomic relationships of three Korean cladodes are discussed in detail.

The unrecorded plant, Aster hispidus var. leptocladus (Compositae), was reported from Mt. Palgong-san, Daegu-si, Korea and was named as `Gin-ssuk-bu-jaeng-i` after its slender leaves. It is distinguished from var. hispidus by having glabrous linear cauline leaves with acute apex, small heads and involucre, short pappus in disc florets. It had been considered as Japanese endemic plant especially adapted to serpentine area.
Phylogenetic study of East-Asia Astragalus L. based on morphological characters

In order to find useful taxonomic morphological characters, 17 taxa from East-Asia Astragalus and Oxytropis anertii were investigated. In this study, seed coat structure, fruit surface, and fruit anatomical structures were selected to classify the species in Astragalus. As a results, useful morphological and anatomical characters in East-Asia Astragalus were life cycle, leaflet shape, raceme, petal color, seed color, pod shape, absent or present of hairs in pod surface, bent degree of dorsal suture, and thickness of endocarp. Using medicinal sources in China, A. floridus, A. membranaceus, A. membranaceus var. mongholicus and A. tongolensis were formed same group. However, these were not completely consensus in the morphological characters. The other hand, A. koraiensis and A. sikokianus, which have controversial taxonomic issue, have clearly no differences morphological characters each other. Therefore, A. koraiensis, A. sikokianus, and A. bhotanensis should be conducted a comparative study on the DNA sequences and molecular cytology in order to clarify the taxonomic treatments in the near future.

Lonicera insularis Nakai (Caprifoliaceae) is Korean endemic plant that lives along the shore of Ulleungdo and Dokdo. The aim of this study is to construct a phylogenetic relationship within six species (L.maackii, L.chrysantha, L.subsessilis, L. harai, L. morrowii) of genus Lonicera L. and Wigela subsessilis as outgroup and intraspecific variation of L. insularis using chloroplast DNA five regions sequences. Sequence analysis revealed that both L. insularis and L. morrowii showed complete homologies in the intergenic regions of trnL-trnF, trnS-trnG, psbM-trnD and matK coding region. However, sequence in the petN-psbM intergenic region showed a single nucleotide difference between both species, thus we designated them as CP01 and CP02. The plants having CP01 are prevalent in the Ulleungdo and Dokdo, while L. insularis and L. morrowii from Ulleungdo and of Dokdo, and Japan have CP02. This confirmed the existence of two cp DNA lineages with different geographical distributions. We can infer the allopatric speciation by geographical barrier. The result will provide the important basal data to study speciation and specie evolution of ocean islands such as Ulleungdo and Dokdo.
Phytogeographic study on the Holocene hypsithermal relict plant populations in the Korean peninsula

The Holocene Hypsithermal Interval(or climatic optimum) was the warmest post-glacial period: temperatures rose to as much as
above present temperatures. We hypothesize that southern plants expanded northward and upward during the Hypsithermal Interval. The Hypsithermal relict populations are defined as populations which distribute mainly in Is. Cheju and Southern subregions and have populations of short-distance dispersion separated by more than 100 km from the nearest distribution. The Hypsithermal relict species were identified and their distributions were mapped based on botanical floras and checklist, herbaria specimens, ecological studies, and field surveys of selected species. Evaluation of the hypothesis was based on reviews of published pollen stratigraphic and paleoecological studies. The results showed that the Holocene Hypsithermal relicts such as Corylopsis coreana Uyeki, Carpinus turczaninowii Hance, Stewartia koreana Nakai ex Rehder were expanded northward during the Holocene Hypsithermal Interval.

The flora of vascular plants in Sumeunmulbaengdui wetland located in Hallasan National Park was surveyed 9 times from September, 2010 to May, 2014. This survey resulted in 236 taxa in total composed of 202 species, 2 subspecies, 27 varieties and 5 forms of 148 genera under 69 families. They were categorized by their life forms into 8 groups of 37 megaphanerophytes, 26 nanophanerophytes, 2 epiphytes, 3 chamaephytes, 84 hemicryptophytes, 33 geophytes, 21 hydrophytes, 30 therophytes. Among them, 10 taxa of Korean endemic plants and 9 taxa of rare and endangered plants were included. In addition, the floristic regional indicator plants were 43 taxa comprised of 3 taxa of grade V, 7 taxa of grade IV, 12 taxa of grade III, 8 taxa of grade II and 13 taxa of grade I. 2 species of alien plants, Erechtites hieracifolia Raf. and Taraxacum officinale Weber were found. Sustainable interest and protective measures to Sumeunmulbaengdui wetland are required, since this area is comparatively larger in size and higher in plant diversity than other Ramsar wetlands in Jeju-do Province.
