Numerical taxonomy of tribe Forsythieae (Oleaceae) in Korea
Kim, Dong-Kap ; Kim, Joo-Hwan ;
Korean Journal of Plant Taxonomy, volume 34, issue 3, 2004, Pages 189~203
Numerical analysis based on 33 morphological characters from 25 populations of 8 species of tribe Forsythieae in Korea was conducted to investigate the taxonomic delimitation and discuss the systematic relationships. In this study, Fontanesia phyllyreoides Labill was adopted as comparing outgroup to discuss the taxonomic status of Abeliophyllum distichum and elucidate the taxonomic relationships between tribe Forsythieae and tribe Fontanesiae. Based on the results of PCA, the sum of contributions for the total variance of three major principal components was 79.6% (PC1 54.2%, PC2 15.4% and PC3 10.0%, repectively). Two dimensional plotting from PCA results recognized three distinct generic clusters. Among the populations of Forsythia, two distinct groups were clustered as I. koreana-saxatilis-viridissima and II. ovata-nakaii. However, 15 populations of Abeliophyllum distichum were arranged randomly without any tendency, and the infraspecies of Abeliophyllum distichum could be recognized as individual variations. Fontanesia phyllyreoides Labill was clustered independently and intertribal limitation was clearly distinguished.
Numerical taxonomy of Rhus sensu lato (Anacardiaceae) in Korea

Numerical analysis based on the 67 morphological characters from 28 populations of 6 species of Korean Rhus sensu lato (Anacardiaceae) was performed for the taxonomic delimitation. Based on the results of PCA with 47 quantitative characters, the sum of contributions for the total variance of three major principal components was 77,9% (PCl 35.2%, PC2 22.5% and PC3 20.2%). The sum of contributions for the total variance of three major principal components were 90,7% (PCl 37.7%, PC2 33.0% and PC3 20.0%) based on the results of PCA with 20 qualitative The characters. Two dimensional plotting from PCA results recognized six distinct species. UPGMA phenogram based on simple matching coefficient method recognized clear taxonomic delimitations among six taxa. On the cluster analysis, qualitative characters were more useful for grouping the species treated. Numerical analysis was very valuable to delimit the Korean taxa of Rhus s.l.
Reconsideration of Prunus sargentii complex in Korea - with respect to P. sargentii and P. takesimensis -

Prunus sargentii complex of subgenus Cerasus is an Eastem Asiatic plant group that exhibits a broad range of morphological variation and includes P. takesimensis, P. yedosensis, P. verecunda, and P. sargentii. In this study, a morphological analysis was undertaken to determine whether the observed morphological variation was primarily attributable to morphological discontinuities among the taxa. P. sargentii, which distributed eastem area in Korea, northern area in Japan and far east Russia had umbel like inflorescence and additionally was characterized by sticky bud and leaf twigs, compared with P. serrulata complex. Also, P. verecunda in Korea and Japan was characterized by umbel like inflorescence and presence of hair in leaf, petiole and pedicel, and was treated as a variety of P. sargentii. Evidence obtained from multivariate morphometric analyses indicated that the entity of P. takesimensis formed a cohesive group somewhat distinct from P. sargenti.. Especially, P. takesimensis was characterized by relatively small flowers (26-32mm in diameter) and many flowers [(2)3-5] per umbel inflorescence, compared with P. sargentii (34-48mm and 2(3) per inflorescence) and should be recognized as an independent and endeImic taxon in Korea. Additionally, P. yedosensis, which was known to have umbel inflorescence (short peduncle type) with pubescent style based on the type specimen, was comprised of corymb inflorescence (long peduncle type) as well. The morphological differentiation between these two types of P. yedosensis was not considered sufficient to warrant recognition of specific status because of the putative hybrid origin, no distinctive geographical distribution pattern, and existence of various peduncle length on Island Jeju-do of Korea.
A taxonomy study on 9 taxa of Carex L. (Cyperaceae) in Korea

For nine taxa of the genus Carex which consist of C. arenicola, C. chordorhiza, C. curta, C. gibba, C. laevissima, C. leiorhyncha, C. neuromrpa, C. maakii and C. remouscula with mixed pistillate and staminate flowers, morphological characters such as inflorescense, spikelet, inflorescence bract, utricle, pistillate and staminate scales, achene, length between two spikelets were observed to find useful characters for their identification. Especially, the shape and the number of spikelet were very useful characters to divide the treated nine taxa into two groups, the their keys were prepared. The first group was comprised of five species of C. arenicola, C. chordorhiza, C. curta, C. gibba, and C. remouscula, which were characterized by broadly oboval or narrowly elliptical shape of spikelet, and 3-9 spikelets per infIorescence and gradual decrease in length between two spikelets. The second group was composed of four species of C. laevissima, C. leiorhyncha, C. neurocarpa, C. maakii, which were distinguished by oval shape of spikelet, and 17-20 spikelets per infIorescence and repetition of increase.
Corydalis namdoensis B.U. Oh et J.G. Kim: A new species of Corydalis sect. Corydalis (Fumariaceae) from Korea

A new species of Corydalis sect. Corydalis (Fumariaceae), C. namdoensis B.U. Oh et J.G. Kim, is described from the central and southern part of Korea. The new species is distinct from its close relative C. albipetala in having very variable leaf shapes, broadly flattened fusiform fruits, seed arrangement nearly in two rows in capsule, V-shaped inner petal apex and limited distribution area.
