Taxonomic identities of Artemisia capillaris Thunb. and A. scoparia Waldst. & Kit.
Park, Myung-Soon ; Nam, Bo-Mi ; Chung, Gyu-Young ;
Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 1~9
Artemisia capillaris Thunb. and A. scoparia Waldst. & Kit. are classified by their root shape, leaf size and capitulum size. However, these characteristics are not nearly as useful when attempting to identify the two species owing to the continuous variation in them. Another important taxonomic characteristics is the habit, whether it is the subshrubs or perennial herbs of A. capillaris Thunb. or the annual or biennial herbs of A. scoparia Waldst. & Kit.. All observed specimens and living individuals in Korea are subshrubs or perennial herbs, and annual or biennial examples are not found. Therefore, it is considered that A. scoparia Waldst. & Kit. is not distributed in Korea.

Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 10~15
Fifteen populations comprising three taxa and a putative hybrid of Fallopia sect. Reynoutria in Korea were examined for their leaf flavonoid constituents. Nineteen flavonoid compounds were isolated and identified; they were glycosylated derivatives of the flavonols quercetin and kaempferol, and of the flavones apigenin and luteolin. Among them, quercetin 3-O-galactoside and quercetin 3-O-glucoside were major flavonoid constituents, and present in all taxa. The flavonoid data appear to be very useful for taxon delimitation, and all taxa examined are readily distinguished by their flavonoid profiles. In addition, the flavonoid data suggest that the Nonsan population may be of hybrid origin involving F. japonica var. japonica, F. forbesii, and F. sachalinensis. In F. japonica var. japonica, there is no apparent correlation between their levels of polyploidy and flavonoid chemistry, but geographical variation of the flavonoid profiles among some populations was detected.
Taxonomic study of Korean Scirpus L. s.l. (Cyperaceae) I. Morphology of Bolboschoenus (Asch.) Palla, Schoenoplectus (Rchb.) Palla, Schoenoplectiella Lye, Scirpus L., and Trichophorum Pers

Scirpus L. s.l. of Cyperaceae has been regarded as a monophyletic group, but the taxa of Scirpus s.l. were rearranged into the five independent genera in recent molecular phylogenetic research: Bolboschoenus (Asch.) Palla, Schoenoplectus (Rchb.) Palla, Schoenoplectiella Lye, Scirpus L., and Trichophorum Pers. In this study, we examined the morphological characteristics and presented the delineation of the five genera of Scirpus s.l., including 21 taxa from South Korea. As a result of our investigation and analysis of domestic collections and those from abroad, the each taxon could be identified using key characteristics of the rhizome features; a cross-section of culm; the degree of development and the width of leaves; the shapes of the membranous region of leaf sheath; and the shapes and size of inflorescence, bract, floral scale, and achene. These major characteristics are illustrated and artificial keys are suggested in this study. In addition, we suggest a new combination for an unrecorded taxon of Schoenoplectiella that was discovered in Gangwon-do, Goseong-gun and give it the Korean name, as 'a-do-song-i-go-raeng-i'.
Comparative seed morphology of Solanaceae in Korea
Kong, Min-Jung ; Lee, Jong-Su ; Hong, Suk-Pyo ;
Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 35~46
The seed morphology of 22 taxa (12 genera) of Solanaceae in Korea was studied by stereo and scanning electron microscopy, and a detailed description of seed morphological features for all examined taxa is provided. The color of the seed is yellow to black, and the shape is reniform to circular. Its size is 0.56-4.29 mm in length and 0.38-3.20 mm in width. The largest sample was found in Datural metel, while the smallest was in Petunia hybrida. Three different surface types (verrucate, verrucate-reticulate, and reticulate) were recognized in the studied taxa. The top of the anticlinal wall produces appendages known as 'fibrils'. This projection of anticlinal wall was found to be specific to the genus Solanum (S. japonense, S. lyratum, and S. lycopersicum). The morphological features (seed shape, size, color, hilum shape, surface type, and fibrils) of the family Solanaceae in Korea are described and their systematic implications are briefly discussed.

Oh, Yong-Cha ; Kim, Sung-Min ; Lee, Chang-Shook ;
Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 47~50
Monochoria vaginalis var. angustifolia (Pontederiaceae) was newly found in a furrow in Imha-ri, Boeun-gun, Chungcheongbuk-do for the first time in Korea. This taxon is distinguished from the other species of the genus Monochoria in Korea by having the smallest plant height, very narrow lanceolate leaves, a cuneate leaf base, and raceme with 1 to 2 flowers. A local name was newly given, 'Ga-neun-moul-dal-ge-bi' for the species. The morphological characteristics and illustrations of the taxon as well as photographs at the habitat are aprovided with a taxonomic key to the species of Monochoria in Korea.
Trichome morphology of Fallopia sect. Reynoutria (Polygonaceae) in Korea
Moon, Hye-Kyoung ; Park, Jin-Hee ; Park, Chong-Wook ;
Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 51~57
The microstructure of the leaf epidermis and trichomes of Fallopia sect. Reynoutria are examined using scanning electron microscopy. Fallopia sachalinensis was distinguished from other taxa in this section by its prominent epicuticular wax layer consisting of protruding wax rodlets. In addition, epicuticular rodlets of F. sachalinensis individuals from Ullung Island and Dok Island appear to be thinner than those from other regions, including Japan and Sakhalin. The stomatal size appears to be related to the ploidy level in the sect. Reynoutria, as the hexaploids, octoploids and dodecaploids tend to have larger stomata as compared to tetraploids. Three basic types of trichomes were found in the section; (1) conical unicellular trichomes, (2) uniseriate filiform trichome consisting of 1-8 cells, and (3) peltate glandular trichomes. The trichome types and their distribution appear to be useful in distinguishing the taxa in the section.
Two new records for the Korean flora: Commelina benghalensis L. and C. diffusa Burm. f. (Commelinaceae)
Kim, Chan-Soo ; Kim, Soo-Young ;
Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 58~65
Commelina benghalensis L. and Commelina diffusa Burm. f. belonging to Commelinaceae, two species previously unrecorded as Korean flora, were collected in the lowlands of Jeju Island in Korea. Commelina benghalensis of the two species is different from others of Commelinaceae in Korea by having funnelform spathes fused at the proximal margin of involucral bracts and cleistogamous flowers. In addition, Commelina diffusa differ from others by having a three-valve capsule and lanceolate and a base cordate or rounded spathelike involucral bracts. The somatic chromosome number of Commelina benghalensis was 2n=2x=22 and the sizes of chromosomes were very small, ranging from 1.25 to 2.70
. However, the Commelina diffusa chromosome number exceeded 2n=ca. 100, and a precise count could not be obtained. These species are known to be distributed in tropical and subtropical regions of Asia and Africa below the latitude of Jeju Island of Korea.

Seo, Won-Bok ; Yoo, Ki-Oug ;
Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 66~80
This study investigated the environmental factors and conducted a RAPD analysis for a better understanding of the environmental characteristics and regional genetic variation in samples from 18 different areas of Viola diamantiaca. The habitats are mostly located on the slopes of mountains facing north at an altitude ranging from 614 m to 1,462 m above sea level with angles of inclination ranging from 3 degrees to 30 degrees. A total of 268 vascular plant taxa are identified in 35 quadrates of 18 habitats. The importance value of V. diamantiaca is 11.58%, and four highly ranked species, Sasa borealis (5.61%), Meehania urticifolia (5.21%), Ainsliaea acerifolia (3.62%), Pseudostellaria palibiniana (3.60%) are considered to have an affinity with V. diamantiaca in their habitats. The degree of their average species diversity is 1.36, while this metric for their evenness and dominance are 0.89 and 0.07, respectively. The average field capacity of the soil is 25.99%, with organic matter at 17.47%, and the pH is 5.19. The soil texture was confirmed as sandy loam of eleven and loam of seven. The result of the RAPD analysis, among 78 bands amplified with a primer, 64 (84.6%) showed polymorphism. Eighteen populations could be classified into five groups with similarity coefficient values ranging from 0.53 to 0.86. The Mt. Jiri population, which is geographically segregated, shows basal branching within the 18 populations. Five populations, including two in the southern district in Gangwon-do and three in Chungcheongbuk-do, form a distinct clade. Four populations in the central district of Gangwon-do and Mt. Bohyeon in the Gyeongsangbuk-do clade form a sister to the clade containing two populations in Gyeonggi-do and five populations of the northern district in Gangwon-do. The Mt. Gariwang population is placed between the southern district and the central district in the Gangwon-do clades.

Korean Journal of Plant Taxonomy, volume 41, issue 1, 2011, Pages 81~86
Two unrecorded Poaceae species, Anthoxanthum glabrum and Saccharum arundinaceum, are herein newly reported from Korea. Anthoxanthum glabrum (Ae-Gi-Hyang-Mo) was found in Ansan-si, Gyeonggi-do, Sangju-si, Gyeongsangbuk-do and Hwasun-gun, Jeollanam-do. It is distinguished from A. nitens by the length of its spikelet, glume and lemma. Saccharum arundinaceum (Keun-Gae-Sa-Tang-Su-Su) was found in Mapo-gu, Gangnam-gu, Seoul, and Hwasun-gun, Jeollanam-do. It is distinguished from S. spontaneum by hair on the lower glume and according to the length of the hair on the callus of its spikelet. In this study, a description and illustrations of the species and photos of the habitat are provided.

Naturalized plants were identified and recorded in South Korea based on field surveys and related literatures. These plants consisted of 321 taxa in total, belonging to 40 families, 175 genera, 302 species, 15 varieties and 4 forms. Among the plants the family Compositae was dominant containing 68 taxa (21.2% of the total population) and Poaceae with 62 taxa (19.3%) successively. Most of the plants were herbs and only 7 taxa trees. 221 taxa (68.8%) appeared to have invaded the country during the third period (1964-2010). 41.8% (134 taxa) of the total population were originated from Europe. These invasive plants were assessed with the degree of naturalisation which was categorized as I-V types.
