The morphological study of Galium L. (Rubiaceae) in Korea
Jeong, Keum Seon ; Pak, Jae-Hong ;
Korean Journal of Plant Taxonomy, volume 42, issue 1, 2012, Pages 1~12
DOI : 10.11110/kjpt.2012.42.1.001
To clarify the morphological variations of Galium, its morphological characteristics were examined using maximum parsimony analysis. The key characteristics as well as the range of variation in each characteristic were investigated at the species level and were employed to elucidate the relationships between the taxa. This study confirmed that species belonging to genus Galium formed a monophyletic group and comprised two main clades. Sect. Cymogaliae and sect. Leptogalium are polyphyly groups, and other sections are monophyletic group. This study also suggests that the fruit hairs, the types of petal apexes, and the colors of the petals are the most valuable taxonomic characteristics for differentiating different sections. The numbers of the leaves and leaf shape provide useful taxonomic characteristics for the identification of different species.

The trnL-F region islocated in the large single-copy region of the chloroplast genome. It consists of the trnL gene, the trnL intron, and the trnL-F IGS. Molecular evolution and phylogenetic relationships in Korean Thalictrum L. were investigated using data from the cpDNA trnL-F region. Bayesian and parsimony analyses of the data set with the gap characteristics recovered well-resolved trees that are topologically similar, with clades supported by some indels evolution. Indel events of cpDNA trnL-F in Korean Thalictrum were interpreted as phylogenetically informative characteristics. Sect. Physocarpum (excluding T. osmorhizoides) was an early-diverging group with in the genus and the remaining section formed strongly supported clades. Korean Thalictrum has various evolutionary patterns, such as the spatial distribution of the nucleotide diversity and transversion-type base substitutions in the trnL-F region.
A palynological study of the genus Artemisia L. (Asteraceae) in Korea
Park, Myung Soon ; Chung, Gyu Young ;
Korean Journal of Plant Taxonomy, volume 42, issue 1, 2012, Pages 24~39
DOI : 10.11110/kjpt.2012.42.1.024
The palynological study of 31 taxa of Korean Artemisia L. was carried out to evaluate their taxonomic characteristics and to determine the relationships among the taxa. The size and shape of the pollen are not used as characteristics to classify the taxa of Korean Artemisia L., but the granule distribution ands pinule connection on the exine were useful for an interspecific classification and for reflecting the relationship between some taxa. It is considered that Artemisia pollen has evolved from a connected spinule and a nearly psilate surface into 1) a connected spinule and a granule surface, 2) a disconnected spinule and a granule surface, 3) a disconnected spinule and a dense granule surface. These pollen characteristics with external morphological characteristics, a geographical distribution and a somatic chromosome number are considered to be good characteristics for distinguishing the relationship of some taxa, such as the A. japonica group (A. hallaisanensis, A. angustissima, A. littoricola) and the A. sacrorum group (A. sacrorum var. sacrorum, A. sacrorum var. incana, A. sacrorum var. iwayomogi).

The NE Asiatic Solidago virgaurea complex in Korea has been reported on 5 taxa (S. virgaurea subsp. asiatica, S. virgaurea var. taquetii, S. virgaurea var. coreana, S. virgaurea subsp. leiocarpa, and S. virgaurea subsp. gigantea). However, the broad morphological variations and a lack of diagnostic characteristics have made it difficult to distinguish these taxa and have thus resulted in a complicated taxonomy in the complex. Therefore, to clarify the classification and delimitation of each taxon, the morphological characteristics of the S. virgaurea complex were investigated by examining the original descriptions and type specimens. Field work was also conducted to investigate the morphological and geographic features. In conclusion, S. japonica Kitam., as a legitimate name, was distributed all over the country except for the Is. Ulleung-do in Korea, as distinguished from S. virgaurea L. Both S. virgaurea var. taquetii and S. virgaurea var. coreana were considered as synonyms of S. japonica, as their morphological characteristics were within the variation range of those of S. japonica. Furthermore, S. virgaurea subsp. leiocarpa does not occur in Korea. Additional investigations are required to clarify the classification of S. virgaurea subsp. gigantea, whose populations were not found during the investigation in this study. S. dahurica, meanwhile, was distributed in the northern part of North Korea.

A comparative study of the petiole anatomy in the tribes Forsythieae (Abeliophyllum, Forsythia) and Fontanesieae (Fontanesia), including one related genus Myxopyrum belonging to Myxopyreae, was carried out using light microscopy. The anatomical characteristics of the distal, medial and proximal parts of the petiole were studied to document any differences. We are described in detail based on their quantitative and qualitative characteristics. Three crystal types (acicular, druse, and prismatic crystals) were found in both Fontanesia and Myxopyrum within all of the studied taxa. Uni-cellular non-glandular trichomes were found in Abeliophyllum and three Forsythia taxa (F. europaea, F. giraldiana, and F. japonica). All features were compared and the vascular patterns of the petiole were distinguished in two types: Type 1A: Trace continuous arc - without crystals (Abeliophyllum, Forsythia), 1B: with crystals (Myxopyrum), Type 2: Trace invaginating at ends with crystals (Fontanesia). A detailed anatomical description of the studied taxa is provided, and its systematic importance is also briefly discussed. In conclusion, some petiole anatomical characteristics (e.g., the main vascular patterns, the presence/absence of crystals) can be useful for diagnostic features as well as partly for supporting the recently proposed molecular phylogeny.
A new record for Korean flora: Drosera spathulata Labill. (Droseraceae)
Son, Sung-Won ; Lee, Byung-Chun ; Chung, Jae-Min ; Yang, Hyung-Ho ; Lee, Seong-Won ;
Korean Journal of Plant Taxonomy, volume 42, issue 1, 2012, Pages 64~67
DOI : 10.11110/kjpt.2012.42.1.064
Drosera spathulata Labill., belonging to the family Droseraceae, was recently recorded for the first time in a forest wetland in Busan-si, Gijang-gun, Cheolma-myeon. This plant is distributed from eastern Australia throughout South East Asian, Japan, China, Taiwan, and now, Korea. This species, related by taxa to D. rotundifolia, is distinguished by possessing a smaller leaf size (10-20 mm long, 2.5-4.5 mm wide), racemes that are glandular-hairy, and pinkish petals. The newly given Korean name, 'Jom-kkeun-kkeun-yi-ju-geok' reflects the small size as compared to related taxa. A description of the key characteristics, an illustration, and photographs of the habitats of this plant are provided in this report.
Sceptridium atrovirens and S. microphyllum (Ophioglossaceae): First report in Korea and its phylogenetic position based on morphology
Lee, Chang Shook ; Kim, Yoo Sung ;
Korean Journal of Plant Taxonomy, volume 42, issue 1, 2012, Pages 68~75
DOI : 10.11110/kjpt.2012.42.1.068
Two unrecorded species (Sceptridium atrovirens and S. microphyllum), previously known only in Japan, were found in a forest in Dosun-dong, Seogwipo-si, Jeju-do for the first time in Korea. S. atrovirens was distinguished from other related species of the genus Sceptridium in Korea by having the thickest rhizome and root, irregularly crenulate or roughly serrate, and a shorter sporophore blade. The local name was newly given as 'Sup-go-sa-ri-sam' for the species, denoting the habitat. S. microphyllum was distinguished by having the smallest plant height, compact sterile blades, and partly lateritious tropophyll in winter. The local name was newly given as 'Aegi-go-sa-ri-sam' for species, meaning of a small size. To reveal the interspecific relationships within the genus Sceptridium in Korea, cladistic analysis was performed for 27 morphological characteristics. The morphological characteristics and illustrations of the two taxa, as well as photographs at the habitat, are provided with a taxonomic key to the species of Sceptridium in Korea.
An unrecorded species from Korea: Poa tuberifera Faurie ex Hack. (Poaceae)
Jung, Su-Young ; Ji, Seong-Jin ; Yang, Jong-Cheol ; Park, Soo-Hyun ; Lee, You-Mi ;
Korean Journal of Plant Taxonomy, volume 42, issue 1, 2012, Pages 76~79
DOI : 10.11110/kjpt.2012.42.1.076
An unrecorded species, Poa tuberifera Faurie ex Hack., was found in Saryeoni forest, Jocheon-eup, Jeju-si, Jeju-do. It can be distinguished from P. acroleuca Steud. and P. acroleuca var. submoniliformis Makino by its morphological characteristics, with panicle branches bearing sparse spikelets and lemmas not wavy-haired at the base. P. tuberifera is known to be an endemic plant of Japan, but its distribution in South Korea is confirmed through the present study.

Two naturalized plants belonging to Plantaginaceae and Labiatae are newly recorded for Korean flora. Nuttallanthus canadensis (L.) D. A. Sutton, a taxon of the unrecorded genus Nuttallanthus (Plantaginaceae), was founded in Seogwipo-si, Jeju-do. This species can be distinguished from the Linaria species by its corolla with a pale blue to a pale purple color, a lower lip longer than the upper lip and seed with 4-7 angles when cross-sectioned. Lamium purpureum var. hybridum (Vill.) Vill. was found in Gwangju Metropolitan city, Jeongeup-si, Jeollabuk-do and Gochang-gun, Jeollanam-do. It can be distinguished from L. purpureum L. by its irregularly dentate bracts and upper lips 3-4 mm in length. New Korean names were given, as Sol-lip-hae-rancho to Nuttallanthus canadensis (L.) D. A. Sutton and Eu-reop-gwang-dae-na-mul to Lamium purpureum var. hybridum (Vill.) Vill. In addition, their descriptions, photos, illustrations and keys to related genera and species are provided here.

Song, Imgeun ; Park, Seonjoo ;
Korean Journal of Plant Taxonomy, volume 42, issue 1, 2012, Pages 98~107
DOI : 10.11110/kjpt.2012.42.1.098
This study was carried out to investigate the non-indigenous of Dokdo belong to Ulleung-gun, Gyeongangbuk-do, Korea, from 2008 to 2011. We divided the study into three steps depending on the recorded times of plants on Dokdo since 1973, when the ecosystem was disturbed by many plantation events. The results are as follows: 30 taxa (52.6%) until 1973, 24 taxa (42.1%) after 1973, and 3 taxa (5.3%) of cultivated plants depending on the 57 taxa of Dokdo. Management of the non-indigenous plants of Dokdo is necessary due to the great increase in interest by people, with many visitors to Dokdo.
