Genetic variation and differentiation among populations of Euphorbia ebracteolata (Euphorbiaceae) in Korea
Cho, Young-Woo ; Park, Ki-Ryong ;
Korean Journal of Plant Taxonomy, volume 45, issue 1, 2015, Pages 1~7
DOI : 10.11110/kjpt.2015.45.1.1
Using starch gel electrophoresis, ten isozyme loci were examined in nine populations of Euphorbia ebracteolata in Korea. Populations of E. ebracteolata tend to have higher within-population levels of genetic variation (A = 2.2, P = 61.1, He = 0.165) along with low levels of genetic differentiation (
= 0.075) compared to previously reported Euphorbia species. The relatively high genetic variation in E. ebracteolata may be due to its long-lived regional distribution and to the outcrossed nature of the species. Low levels of genetic differentiation and the absence of unique alleles in E. ebracteolata populations suggest that Korean populations diverged recently. This study does not support the recognition of var. coreana and for. magna as separate taxa, and suggests that they should be combined with E. ebracteolata.

A new species, Fimbristylis drizae J. Kim & M. Kim, is named and described from Sucheong Lake, Jeongeup-si, Jeollabuk-do, Korea. Fimbristylis drizae shares several characters (five-angled culm, 1-2 bladeless sheath, and compound anthela inflorescence) with the related species F. diphylloides Makino. It is, however, distinct from F. diphylloides, which has two to three stigmas, ovate spikelets, two stamens, a blackish brown scale, and a roadside habitat. In contrast, the new species has two stigmas, oval spikelets, one (or rarely two) stamens, a yellowish brown scale, and a lakeside habitat.

Draba ussuriensis Pohle is reported from Mt. Baekdu in this paper as a new member of Korean flora. D. ussuriensis is a white-flowered perennial herb and similar to Draba mongolica Turczaninow. However, D. ussuriensis differs from Draba mongolica Turczaninow in a number of characters. The stems and pedicels of D. mongolica are covered by dense trichomes, while those of D. ussuriensis are glabrous or glabrescent. D. ussuriensis has fewer cauline leaves compared to D. mongolica. The Korean name of D. ussuriensis Pohle stems from the specific epithet of its scientific name. In addition, D. mongolica is a new name, replacing the previously misidentified names of D. glabella Pursh, D. daurica DC., D. incana L., and D. nipponica Makino in several different studies. We corrected the name based on a comparative morphological study of specimens collected from Mt. Baekdu and Gwanmobong and related species. As a result, Korean Draba consists of three species: two white-flowered species and one yellow-flowered D. nemorosa L.
A new species of Huperzia (Lycopodiaceae) from Jeju Island, Korea: Huperzia jejuensis
Lim, Jina ; Sun, Byung-Yun ;
Korean Journal of Plant Taxonomy, volume 45, issue 1, 2015, Pages 17~21
DOI : 10.11110/kjpt.2015.45.1.17
A new species belonging to Lycopodiaceae Mirb. Huperzia Bernh. s.l. is described and illustrated: Huperzia jejuensis B.-Y. Sun & J. Lim. H. jejuensis has been considered conspecific with H. integrifolia (Matsuda) B.
llg. ex. Z. Satou, but it is clearly distinguished by the characteristics of linear-lanceolate leaves with parallel margins from the base to the mid-part, minute dentate margins from the mid-part to the end of the leaf, and cuspidate gemma apex. Because the habitat of the new species was confined to Jeju Island, 'jejuensis' was chosen as the specific epithet of the scientific name of the new taxon.
A new distribution of Dalbergia hupeana Hance (Fabaceae) in Korea and its taxonomic characteristics
Choi, In-Su ; Jin, Dong-Pil ; An, Suk-Ja ; Choi, Byoung-Hee ;
Korean Journal of Plant Taxonomy, volume 45, issue 1, 2015, Pages 22~28
DOI : 10.11110/kjpt.2015.45.1.22
A new distribution of Dalbergia hupeana has been reported at Mt. Yudal in Mokpo-si, Korea. It was previously thought to be restricted to China, but is now recognized as a new addition to Korean flora. Species identification was confirmed according to morphological characteristics and DNA sequences. The genus Dalbergia is clearly distinguished from other leguminous tree species in Korea due to its diadelphous (5+5) stamens. Here, we describe the characteristics of the genus and species and speculate about whether its origins are native or introduced in Korea.

Sasa borealis (Hack.) Makino & Shibata is widely distributed in South Korea. With amplified fragment length polymorphism (AFLP) markers, we analyzed the genetic diversity of S. borealis to predict and measure the phytogeographical factors of these populations. Relatively high levels of genetic diversity (PPL = 37.2%, h = 0.143, I = 0.205) and genetic differentiation (
= 0.395) were confirmed in populations of S. borealis. Moreover, an analysis of molecular variance (AMOVA) showed that the rate of differentiation among the populations was 47.7%. The results showed that genetic diversity is inversely proportional to the latitude of the S. borealis populations, indicating that the distribution of S. borealis may have extended from lower to higher latitudes. This method of investigating the correlation between genetic diversity and latitude presents critical information for estimating changes in distributions and plant conservation due to climate change.
Melia toosendan and M. azadarach are a single species due to their genetic similarity
Kim, Hoe-Won ; Yeon, Seung-Woo ; Kim, Ki-Joong ;
Korean Journal of Plant Taxonomy, volume 45, issue 1, 2015, Pages 36~44
DOI : 10.11110/kjpt.2015.45.1.36
The nucleotide sequences of six markers, including nuclear ITS, chloroplast matK, rbcL, atpF-H, psbK-I and psbA-trnH, were analyzed for the plants known as Melia toosendan collected in Southwest China; M. azadarach planted in Southeast China, Korea and India; and species related to Sapindaceae in order to clarify the species boundary between M. toosendan and M. azadarach. The result of a phylogenetic analysis using the nuclear ITS and five chloroplast marker sequences determined that the plants known as M. toosendan and M. azadarach are the same species. These two species have been treated as a single species or as two different species depending on the researcher. The result of the present study supports the contention that the two species are the same. In addition, a sister species to M. azadarach registered in various countries with various basionyms is Azadirachta indica, a well-known medicinal plant. It has previously been classified as a member of the genus Melia.

This study was carried out to investigate the flora of Mt Hanseok (Inje-gun, Gangwon-do) from March, 2013 to August, 2014. Vascular plants were summarized, numbering 603 taxa including 101 families, 337 genera, 520 species, 5 subspecies, 69 varieties and 9 forms. Among the 603 investigated taxa, 14 Korean endemic, 17 rare plants and 99 plants specially designated by the Ministry of Environment were also included. Naturalized plants amounted to 37 taxa. The percentage of naturalized plants species and the urbanization index were estimated to be 6.1% and 11.5%, respectively. Useful plants of the 603 taxa listed consist of 223 taxa (36.9%) which are edible plants, 217 taxa (35.9%) which are pasture plants, 165 taxa (27.3%) as medicinal plants, 67 taxa (11.1%) as ornamental plants, 22 taxa (3.6%) which are timber plants and 9 taxa (1.4%) of miscellaneous plants.

In order to illustrate the flora of vascular plants distributed in the area of Mt. Hambaek-san and its neighboring mountains, the authors collected vascular plants intensively on Mt. Hambaek-san (1,573 m), Mt. Geumdae-bong (1,418 m) and Mt. Daedeok-san (1,307 m) from April of 2012 to August of 2014. All of them consisted of 90 families, 310 genera, 532 species, 4 subspecies, 73 varieties and 13 forms, with a total of 622 taxa. The total number of vascular plants in the investigated area was 808 taxa (17.55% of all vascular plants in Korea) with the addition of voucher specimens from previous investigations. Among the collected plants, endemic ones were 21 taxa, rare and endangered ones 26 taxa, naturalized ones 30 taxa, useful ones 464 taxa, and floristically specific ones of Korean floristic zones 62 taxa except for species of the first and second grade. Among the floristic zones of the Korean Peninsula, this investigated area showed the typical vegetation of a temperate middle province into which more northern elements than southern elements flowed.

This study presents a comprehensive account of the flora of hydrophytes and hygrophytes on Jeju Island. This approach aims to contribute to fundamental information about the conservation of plant diversity in wetlands. Field surveys were carried out from May of 2010 to September of 2014 in various types of wetlands on Jeju Island. A total of 189 taxa, including 52 families, 98 genera, 181 species, 6 varieties, 2 forma and 189 taxa, were found. Among them, 99 taxa (38 families, 60 genera, 96 species and 3 varieties) were hydrophytes and 90 taxa (23 families, 45 genera, 85 species, 3 varieties and 2 forma) were hygrophytes. In addition, Eleocharis
yezoensis H. Hara (Cyperaceae) was newly added to the flora of Korea. The protected wild plants designated by the Ministry of the Environment were 5 taxa, including Brasenia schreberi J. F. Gmel. and Dysophylla yatabeana Makino. The endangered species found included one Critically Endangered Species (i.e., Mankyua chejuense B.-Y. Sun, M. H. Kim & C. H. Kim), 5 Endangered Species (e.g., Lysimachia leucantha Miq.) and 7 Vulnerable Species (e.g., Tillaea aquatica L.). The floristic regional indicator plants found in this area were 44 taxa comprising 10 taxa of grade V, 7 taxa grade IV, 15 taxa of grade III, 5 taxa of grade II, and 7 taxa of grade I. The identified naturalized plants were 10 taxa; 8 families, 8 genera, 9 species and 1 variety. In the wetlands on Jeju Island, high plant species diversity was shown, and a number of rare plants and phytogeographically important plants were found. For these reasons, we consider that the wetlands on Jeju Island are very important areas from a botanical point of view. It is necessary to establish specific protection and maintenance policies in an effort to conserve these wetlands and species.
