Korean Journal of Plant Taxonomy, volume 40, issue 4, 2010, Pages 193~201
The Ryukyus Archipelago consists of about 200 nearly subtropical islands located between Japan proper and Taiwan. Previous studies have found the Ryukyus to be a region of high biodiversity with many endangered vascular plant taxa, but they are not comprehensive. Here, we discuss the phytogeographic features and circumstances of the endangered plant taxa, make suggestions for effective in situ conservation, and highlight endangered plants in the Ryukyus that require further study.

The most useful criteria and selection procedures of biological indicators have been developed in Korea because they have taken into account local and national concerns on biological responses against climate change. On the basis of these criteria and selection procedures, 100 climate-sensitive biological indicator species were selected to predict biodiversity distribution shift by climate change and manage biological resources integratedly at the national level. It is expected that selection and monitoring of biological indicators by climate change will provide significant information to prepare protective strategies of vulnerable species against climate change and adaptive policies under the changing environment in Korea. In this paper, we have reviewed what kinds of criteria were considered in selecting bioindicators to assess responses of biological organisms against climate change. Definition and selection steps of bioindicators were proposed, and the 100 species of climate- sensitive biological indicators were selected out of 33,253 taxa reported in Korea.

Korean Journal of Plant Taxonomy, volume 40, issue 4, 2010, Pages 208~217
Crossosomatales is a recently recognized order in the rosid II clade with about 64 species in eight morphologically distinct families that have been previously classified in as many as 15 other orders. Phylogenetic relationships among the families and genera within Crossosomatales were investigated using chloroplast atpB, matK, and rbcL sequences employing maximum parsimony, maximum likelihood, and Bayesian methods. The phylogenetic framework was used to examine the patterns of morphological evolution and synapomorphies for subclades within Crossosomatales. The combined data with representative species from all genera in the order strongly supported monophyly of Crossosomatales. Strong support was found for the families in the Southern Hemisphere, in which Aphloiaceae is sister to the clade of (Geissolomataceae, (Ixerbaceae + Strasburgeriaceae)). The sister relationship between the Southern Hemisphere clade and families distributed primarily in the Northern Hemisphere was also supported. As in the previous studies, following relationships were found within the Northern Hemisphere clade: Staphyleaceae is sister to a clade of (Guamatelaceae, (Stachyuraceae + Crossosomataceae)). The pattern analysis indicates that evolutionary pattern of morphological characters is complex, requiring multiple changes within Crossosomatales. Several reproductive traits, such as inflorescence, aril, stigma, and conspicuous protrusion from pollen aperture, corroborate the molecular phylogeny.

A total of ten unrecorded liverwort species in the Hepaticae flora of Korea were collected on Mt. Deogyu (1,614 m). The ten species are Tetralophozia filiformis (Steph.) Urmi., Herbertus buchii Juslen, Bazzania japonica (Sande Lac.) Lindb., Cephaloziella hampeana (Nees) Schiffner ex Loeske., Jungermannia japonica Amak., Marsupella alpina (Gott. ex Husn.) Bernet., Pedinophyllum interruptum (Nees) Kaal., Frullania polyptera Tayl., Jubula hutchinsiae ssp. javanica (Steph.) Verd., and Marchantia polymorpha ssp. montivagans Bischl. and Boisselier-Dubayle. They are distributed near streams and/or at the top of a ridge on Mt. Deogyu.

An intensive study of the embryology of Gymnospermium microrrhynchum was conducted to provide information regarding a discussion of the phylogenetic relationships of the genus, which is yet unstudied. Our results indicated that Gymnospermium is similar to other genera of Berberidaceae in terms of its embryological features. Nevertheless, newly reported and unique features are the well-developed endothelium and the undifferentiated seed coat type. Until the study of Gymnospermium, it may have been considered to be closer to Caulophyllum and Leontice in the tribe Leonticeae. These three genera share many morphological features as well as molecular similarities, by which they are kept in the same tribe, Leonticeae. However, very little detailed embryological data regarding these genera have been published thus far. Gymnospermium was characterized according to the basic type of anther wall formation as well as its glandular tapetum, successive cytokinesis in the microspore mother cell, two-celled mature pollen grains, anatropous and crassinucellate ovules with a nucellar cap, well-developed endothelium, its Polygonum type of embryo sac formation, its nuclear type of endosperm formation, and its undifferentiated seed coat type. In comparison with Nandina, there are many differences, such as the dehiscence of the anther, the cytokinesis in the microspore mother cells, the shape of the megaspore dyad, and the seed characteristics. Although we had no available detailed embryological information regarding Caulophyllum and Leontice, which are genera that are more closely related to Gymnospermium, we could deduce from the phylogenetic relationship that Gymnospermium, Caulophyllum, and Leontice are more closely related to each other than other genera of Berberidaceae on the basis of the seed characteristics.

The taxonomy of umbel genus Sium L., Apiaceae in Korea was reviewed on the basis of molecular phylogenies derived from sequences of nuclear ribosomal DNA internal transcribed spacer (ITS) regions. The ITS sequence-derived phylogeny indicates that S. heterophyllum, endemic to Korea, is identical to S. tenue, which is known as endemic to Ussuri regions. Comparisons of sequence pairs across both spacer regions gave divergence values and revealed the identity between S. tenue and S. heterophyllum on Mt. Moonsoo. On the other hand, the ITS sequences support species delimitation of S. ternifolium, as reported recently as a new species that differs from other Sium species. The ITS sequence divergence values of 1.4 and 1.6% support species delimitation between S. serra and S. ternifolium.

Two newly naturalized species were recorded from Incheon (Youngjong-do) and Ulsan. Among them, Bidens polylepis S.F. Blake (Asteraceae) was widespread and was found in the following locations: Unbuk bridge, Unbuk-dong, Jung-gu in Incheon, and Chuiseosan, Banggi-ri, Samnam-myeon as well as a Saemmul mountain cabin on Jaeaksan, Sangbuk-myeon in Ulju-gun, Ulsan. Bidens polylepis can be distinguished from congeneric species by its larger ray-flowers. The Korean name of Bidens polylepis was newly formulated based on the characteristic of its yellow ray-flowers and on the Korean name of the genus Bidens (Asteraceae). The other species, numerous populations of Saponaria officinalis L. (Caryophyllaceae) were found in two areas in Jeotgae village, Unseo-dong, Jung-gu, Incheon. Saponaria officinalis can be distinguished from congeneric species in the family by two features, shallow calyx teeth and a petal with appendages at the base of the blade.

Korean Journal of Plant Taxonomy, volume 40, issue 4, 2010, Pages 247~250
We report Polygonum plebeium R.Br. (Polygonaceae) as an unrecorded species from the Geumgang River, Buyeo-gun; Galmae-dong, Guri-si; the Chungju Reservoir, Jecheon-si; the Daecheong Reservoir, Okcheon-gun; and the Daecheong Reservoir, Daejeon, in Korea. It is distinguished from P. aviculare by pedicels that articulate in the middle and by its smooth and shiny achenes. The new Korean name, 'Ae-Gi-Ma-Di-Pul', is given considering the small-sized plant. In this study, a description and illustrations of the species and photos of the habitat are provided.

Korean Journal of Plant Taxonomy, volume 40, issue 4, 2010, Pages 251~254
We describe a new taxon of Goodyera (Orchidaceae), G. x tamnaensis N.S. Lee, K.S. Lee, S.H. Yeau & C.S. Lee, sp. nov., from Jeju Island. This taxon is presumed to be a hybrid between G. schlechtendaliana and G. velutina based on several morphological characteristics, i.e., leaf venation, a patterned leaf surface and raised leaf epidermal cells, the color of the flower and the bract, the lateral sepal shape, and the hair length. The morphological characteristics and illustrations of the species based on the holotype are provided together with photographs of the habitat.
A New Species of Asarum: A. yeonbyeonense M. Kim & S. So
So, Soon-Ku ; Hwang, Yong ; Lee, Chung-Hee ; Kim, Mu-Yeol ;
Korean Journal of Plant Taxonomy, volume 40, issue 4, 2010, Pages 255~261
A new species, Asarum yeonbyeonense M. Kim & S. So, is named and described from Mt. Baekdu in Korea. This new species is distinctly different from the related species A. mandshuricum (Maxim.) M. Kim & S. So according to the purple band at the base of the calyx lobes and the thick calyx lobes. In addition, Asarum sieboldii var. viridiluteolum Y. Lee is closely related to A. yeonbyeonense M. Kim & S. So due to its reflexed calyx lobes; however, this variety has green calyx lobes and pubescent petioles. Therefore its scientific name was changed to Asarum yeonbyeonense var. viridiluteolum (Y. Lee) M. Kim & S. So, and its Korean name should be changed into Nokyeonbyeon-Jokdoripul.

Korean Journal of Plant Taxonomy, volume 40, issue 4, 2010, Pages 262~266
A new variety of Elsholtzia splendens (Lamiaceae) was found by the roadside of a mountain base at Jungmun-dong, Seogwipo-si, Jeju-do. The new taxon is termed Elsholtzia splendens var. fasciflora N.S. Lee, M.S. Chung & C.S. Lee, var. nov. The Korean name 'Da-bal-kkot-hyang-yu' was given. The morphological characters and illustrations of the species based on the holotype are provided together with a photograph of the habitat. It is distinctly distinguished from Elsholtzia splendens var. splendens by a few characteristics: leaves that area 2-4 cm long, leaves beneath the inflorescence, typically mostly 4; and inflorescence mosyly 2-4, fascicled, involucres oval.

Korean Journal of Plant Taxonomy, volume 40, issue 4, 2010, Pages 267~273
The distribution of three typical warm-temperate evergreen trees, Quercus acuta Thunb., Neolitsea sericea (Blume) Koidz., and Machilus thunbergii Siebold & Zucc., were surveyed on the Korean Peninsula based on field and specimen investigations and the distribution maps of the three species were prepared. The distribution patterns of the species correspond to the south coast floristic region in Korea, which includes the distributional areas of Jeju-do, Isl. Ulleung, the southern coastal areas, and the areas up to the islands around Incheon in the Yellow Sea. The northernmost limit of the distribution of Quercus acuta is Isl. Nap of Incheon in the west, and a new distribution was found at Isl. Ulleung in the East Sea; additionally, the limit of Neolitsea sericea is the Deojoek archipelago of Incheon. The northernmost limit of Machilus thunbergii is Isl. Daecheong of Incheon, which is the highest latitude among those of the three species. This distribution survey of evergreen broad-leaved trees in Korea can be used as basic data for the delimitation of floristic regions and as a bio-indicator of climatic change.

This study was performed to report the augmented wild populations of Forsythia koreana (Rehder) Nakai and Abeliophyllum distichum Nakai in Korea. Forsythia koreana was found in Budong-myeon, Cheongsong-gun, Gyeongsangbuk-do. The overall size of the natural habitat of Forsythia koreana is 5 m
5 m. A total of 12 individuals were recorded in the wild, and 3 of them were in the seedling stage. The wild habitat is in a secondary forest, which is co-dominated by Pinus densiflora Siebold & Zucc and Robinia pseudoacacia L, with 15% coverage. The coverage of the shrub layer is 40% and is dominated by Spiraea prunifolia for. simpliciflora Nakai. The natural habitat of Abeliophyllum disitichum, which is recorded in Uisong-up, Gyeongsangbuk-do, is distributed in sites characterized by boulders along streams, with a patchwork of 15 scattered areas over a habitat size of 50 m
15 m. Quercus variabilis Blume is a dominant species in this habitat, with this species dominating at the sub-tree layer. Celtis aurantiaca Nakai also dominates at the shrub layer. The natural ranges of these two species in Korea were mapped based on the terms of the extent of occupancy (EoO).
