First record of Myriophyllum oguraense Miki (Haloragaceae) in Korea
Choi, Hyeok Jae ; Jang, Ju-Eun ; Cheong, Seon-Woo ; Shiga, Takashi ;
Korean Journal of Plant Taxonomy, volume 44, issue 2, 2014, Pages 77~80
DOI : 10.11110/kjpt.2014.44.2.77
Here we report a previously unrecorded species of Korean Myriophyllum L. (Haloragaceae). This taxon, M. oguraense Miki has been regarded as a Japanese endemic for some 60 years. Myriophyllum oguraense and its closely related M. verticillatum L. share the characteristic of having pectinate emergent leaves that are similar in shape to, but much smaller than, the submerged leaves. However, the primary characteristic that differentiates these taxa is the turion shape (club shaped in M. verticillatum and linear in M. oguraense). The common name, `Gin-dong-a-mul-su-sae-mi` was also newly given considering its characteristic turion shape. Photographs and a key to Korean Myriophyllum species are provided in addition to complete descriptions including information on nomenclatural types, distributions and specimens examined.

DOI : 10.11110/kjpt.2014.44.2.88
An unrecorded species, Carex aequialta K
k. (Cyperaceae), was found in Yecheon-gun, Gyeongsangbuk-do and Jeju-si, Jeju-do. This species is distinguished from related taxa, C. maximowiczii Miq., C. suifunensis Kom., C. phacota Spreng., C. dimorpholepis Steud., C. shimidzensis Franch. and C. tegulata H. Lev. & Vaniot, by having suberect lateral spikes, awnless pistillate scales, short rhizomes and corymblike inflorescences. This taxon was named `Mul-kko-ri-sa-cho` in Korean based on its external appearances and habitat. We provide its description, illustrations, photographs and the key of related taxa in Korea.
Leaf anatomy of Pinus thunbergii Parl. (Pinaceae) collected from different regions of Korea
Ghimire, Balkrishna ; Kim, Muyeol ; Lee, Jeong-Ho ; Heo, Kweon ;
Korean Journal of Plant Taxonomy, volume 44, issue 2, 2014, Pages 91~99
DOI : 10.11110/kjpt.2014.44.2.91
Leaf anatomical study of Pinus thunbergii collected from 12 different coastal regions of Korea was conducted to understand the adaptive variation on leaf traits. Basic anatomical features are typical pine needle type with fibrous epidermis, 2-3 layered hypodermis, sunken stomata, monomorphic mesophyll, and well-represented bundle sheath. The bundle sheath surrounds a couple of vascular bundle separated by parenchyma bands. On the basis of their position, the resin ducts are of three types; external, medial and internal of the bundle sheath. The total number of resin ducts in all samples varies from 4 to 12. The stomata were found on stomatal bands throughout the leaf surface. Important dissimilarities observed on P. thunburgii leaf are the number and position of resin ducts and the number of stomata rows in leaf surface.
A taxonomic reexamination of Saussurea pseudogracilis (Compositae)
Sun, Eun-Mi ; Jang, Jeong-Won ; Kim, Byeol-Ah ; Chung, Jae-Min ; Son, Sung-Won ; Im, Hyoung-Tak ;
Korean Journal of Plant Taxonomy, volume 44, issue 2, 2014, Pages 100~110
DOI : 10.11110/kjpt.2014.44.2.100
Saussurea pseudogracilis Kitam. is characterized by its slender leaves, small involucre and small number of involucral bracts compared to Saussurea gracilis Maxim. But some taxonomists insist that it is hard distinguih S. pseudogracilis from S. pseudogracilis. We tried to discern taxonomic identification of S. pseudogracilis by measuring and analyzing 45 qualitative characters and 42 quantitative characters on 165 specimen. S. pseudograilis was not distinguished from S. gracilis not only by qualitative characters but also by quantitative characters even on statistical analysis(PCA). Therefore, S. pseudogracilis is not independent taxonomic species and it is proper to consider S. pseudogracilis as a synonym of S. gracilis.
Molecular phylogenetic study of Pinus in Korea based on chloroplast DNA psbA-trnH and atpF-H sequences data
Hong, Jeong-Ki ; Yang, Jong-Cheol ; Lee, You-Mi ; Kim, Joo-Hwan ;
Korean Journal of Plant Taxonomy, volume 44, issue 2, 2014, Pages 111~118
DOI : 10.11110/kjpt.2014.44.2.111
This study aims to define the phylogenetic relationship within Korean Pinus L. and to find the molecular markers which resolve the phylogenetic relationship in genus Pinus. cpDNA atpF-H and psbA-trnH regions were used as molecular markers. We performed the molecular phylogenetic study on 17 taxa of Pinus in Korea. The combined analyses of two gene loci showed that Korean Pinus was a monophyletic group supported by 100% BP. According to the results of separate analyses, psbA-trnH region seems to work better resolving power to clarify the phylogenetic ambiguity in Korean Pinus than those of atpF-H region. Also, we tried to checked the value and resolution of two chloroplast DNA loci on phylogenetic implications.

A comparative study of leaf anatomy in tribe Sorbarieae (Adenostoma, Chamaebatiaria, Sorbaria, Spiraeanthus) including one related genus Lyonothamnus was carried out using light microscopy. Anatomical characteristics of the leaf blade and midrib were described and taxonomically evaluated. The anatomical characters which described in this study are as follows: thickness of leaf midrib, blade in cross section, cuticle, epidermal cell, stoma, trichome, mesophyll, crystal, main vasculature type. All features were compared and the vascular patterns of midrib were distinguished two types. - Type 1: Trace tripartite (Adenostoma), Type 2: Trace continuous, subtype 2A: flat arc (Chamaebatiaria, Spiraeanthus), subtype 2B: U-shape arc (Lyonothamnus, Sorbaria). In conclusion, some of leaf anatomical characters (e.g., cuticle, epidermal cell, trichome, mesophyll, main vasculature type) can be useful for diagnostic features. Hypostomatic type, dorsiventral mesophyll, Ushape vasculature type would constitute a major characters for genus Sorbaria in Sorbarieae. The detailed anatomical description of studied taxa is provided, and its systematic importance is also briefly discussed.

A newly naturalized plant, Amaranthus powellii S. Watson was found Jail-dong, Uijeongbu-si, Gyeonggi-do, Korea. This species is native to Southwestern USA and Northern Mexico, and it is also naturalized in worldwide of temperate regions. This species was distinguished from the related species, A. patulus Bertol. and A. hybridus L., by leave blades broadly elliptic, rhombic or lanceolate, petals unequal, without conspicuous green mid-veins, and utricle gradually narrowed toward the stigma. Korean name was given as `Min-teol-bi-reum` to A. powellii S. Watson, based on the character, it was hairy less than the three related species, A. patulus Bertol., A. hybridus L. and A. retroflexus L., conspicuously. Descriptions for mophological characters, photographs, illustrations and keys to allied taxa were provided.
