Phylogenetic Relationships of Korean Viola (Violaceae) Based on matK and atpB-rbcL Sequence Data of Chloroplast DNA

Korean Journal of Plant Taxonomy, volume 37, issue 1, 2007, Pages 1~15
Phylogenetic studies were conducted ofr 42 populations of Korean viola based on matK gene and atpB-rbcL intergenic spacer region of chloroplast DNA. In the matK tree, section Chamaemelanium and Dischidium were formed as a distinct group. Five subsections of section Nomimium were paraphyletic. In atpB-rbcL intergenic spacer region analysis, two species of sect. Chamaemelanium were monophyletic, and section Dischidium was placed sister ti subsection patellares clade except for V. keiskei. Five subsections of section Nomimium were also paraphyletic as matK tree. the separate data analyses were incongruent in the relationships among 42 populations, especially for the position of section Dischidium and V. keiskei. The combined analyses of two chloroplast regions showed three major clades; section Chamaemelanium and Dischidium (x=6) formed a sister to subsections Hypocarpae and Trigonocarpae (x=10) clade; subsections Bilobatae and vaginatae (x=10 or 12) formed a clade with V. keiskei; and 19 populations of subsection patellares (x=12) except for V. keiskei were recognized as an independent clade within section Nomimium. Although combined data suggest three major clades of Korea viola, the origins of each clade from outgroup were discordance with previous ITS and trnL-F data.

Korean Journal of Plant Taxonomy, volume 37, issue 1, 2007, Pages 17~40
Patterns of morphological variation in Korean Cirsium were examined using numerical analysis, and the delimitation of taxa was evaluated. Principal components analysis of individuals of taxa using 61 morphological characters revealed the presence of two major groups. One group included C. lineare, C. vlassovianum, and C. setidens, the other contained C. pendulum, C. japonicum var. japonicum, C. japonicum var. spinosissimum, C. schantarense, C. nipponicum, and C. rhiniceros. Also, the result of cluster analysis recognized three sections, Onotrophe, Pseudo-eriolepis, and spanioptilon. Korean Cirsium was classified inti three sections; C. japonicum var. japonicum, C. japonicum var. spinosissimum, C. schantarense, C. rhiniceros and C. nipponicum were belonged to sect. Onotrophe, C. setidens, C. vlassovianum and C. lineare were belonged to sect. Spanioptilon, and C. pendulum was belonged to sect. Pseudo-eriolepis. In conclusion, Korean Cirsium was classified inti three sections, eight species, three varieties, and five form.

This study was to establish the floristic composition of northern region in Gyeonggi-Province area(126〫〫〫˚ 45' - 127˚ 37' E, 37˚ 31' - 38˚ 17' N). This work was investigated from April, 1988 to October, 2004. The flora of vascular plants of northern region in Gyeonggi-Province were consisted of total 2,030 taxa; 145 families, 656 genera, 1,611 species, 7 subspecies, 320 varieties, 1 subvarieties and 91 formae. Among them, Korean endemic species were composed of 46 families, 85 genera, 84 species, 35 varieties, 1 subvarieties, and 18 formae, total 138 taxa. The rare and endangered plants based on floral region indicated by Ministry of Environment were 416 taxa; V rank species 18 taxa, IV rank species 79 taxa, Ⅲ rank species 111 taxa, Ⅱ rank species 80 taxa, Ⅰrank species 128 taxa. Also the naturalized plants were 114 species, correspond to 39.7% of among total 287 species appeared in South Korea. the result of PCA, Gwangju mountain chain at northern region of Gyeonggi-Province has rich and diverse vascular plants, and there are many Korean endemic, rare and endangered plants. therefore Gwangju mountain chain must be the core axis in for conserving the plant biodiversity and richness.
A taxonomic Study of Lysimachia sect. Spicatae (Primulaceae) Based on Morphological Characters
Kim, Jin-Man ; Tae, Kyoung-Hwan ; Kim, Joo-Hwan ;
Korean Journal of Plant Taxonomy, volume 37, issue 1, 2007, Pages 61~78
The general morphological characters of Lysimchia sect. Spicatae were reviewed. From the results, numerical analyses were conducted based on 34 morphological characters from 14 populations of three species in Korea in order to investigate the key characters among the treated taxa and taxonomic delimitation and to discuss the systematic relationship. Habitat, leaf apices, presence or absent of hair on leaves, stipules, stems and bracts, branch of stems, kind of hair on floral axis and pedicels, shape of florescens were important diagnostic characters to identify the species. The relationship between Lysimachia clethoides and L. ba교stachys was more close than that of L. fortunei based on the quantitative characters. Also, a new key was made up from the result.
A Naturalized Plant of Lespedeza (Leguminosae) in Korea: L. floribunda Bunge
Han, Jeong-Eun ; Choi, Byoung-Hee ;
Korean Journal of Plant Taxonomy, volume 37, issue 1, 2007, Pages 79~85
A naturalized plant of Leguminosae is reported in Korea. L. fioribunda belongs to subgenus Lespedeza of Lespedeza which is characterized by having chasmogamous flowers. The plant is native in China and recently naturalized in Seoul and Chungcheongnam Province of Korea. A key to the species of subgenus Lespedeza in Korea including L. floribunda is provided.
