Taxonomic review for the Cyrnopterus melanotilingia (H. Boissieu) C. Y. Yoon in Apiaceae
Koo, Ja-Choon ; Kim, Mu-Yeol ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 345~358
The systematic position of Cymopterus melanotiligia (H. Boissieu) C. Y. Yoon in Apiaceae was revaluated based on the ITS sequence data. Its diagnostic characteristics include its asymmerty mericarps, 3-4 mericarp ribs, winged dorsal ribs, and ternate leaves. It is morphologically similar to Tilingia tsusimensis and Pimpinella having ternate leaves. It is distinguished from Ostericum having symmerty mericarps, 5 mericarp ribs, and rounded dorsal ribs. Also it looks like Angelica with broadly winged lateral ribs and strongly dorsally compressed mericarps, but is distinguished by having its conspicuous calyx teeth and unilayer pericarps. Cymopterus melanotiligia formed a different clade group with Cymopterus species distributed in North America based on ITS sequences, and it supports the close relationships with Halosciastrum melanotilingia. Thus, we conclude that this species is here referred to Halosciastrum melanotilingia (H. Boissieu) Pimenov & Tikhomirov.
Comparative study of fruit wall structure in Lapsana L. and Lapsanastrum J. H. Pak & K. Bremer (Asteraceae; Lactuceae)
Pak, Jae-Hong ; Choi, Kyung ; Ito, Motorni ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 359~370
The mature fruit wall structures were investigated in Lapsana communis, its six subspecies and the four species of Lapsanastrum (Asteraceae; Lactuceae). Lapsanastrum differs from Lapsana communis in some features: two or three protrudent costae verse equally developed costae, hairly versus glabrous exocarp, respectively. Moreover, Lapsana has no sclerenchymatous‐fiber cells in mesocarp, while Lapsanastrum has sclerenchymatous fiber cells. The differences in fruit wall structure between Lapsana and Lapsanastrum obviously support the separation of Lapsanastrum from Lapsana s. lat.
Phylogenetic relationships of Coryloideae based on waxy and atpB-rbcL sequences
Yoo, Ki-Oug ; Wen, Jun ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 371~388
Phylogenetic studies were conducted for 35 populations of the subfamily Coryloideae (Betulaceae) based on waxy gene of nuclear DNA and atpB-rbcL intergenic spacer region of chloroplast DNA. Waxy data analysis suggest that Coryloideae is monophyletic; Corylus is monophyletic and basally branching within the subfamily Coryloideae; Ostryopsis is sister to the Carpinus and Ostrya clade, and the Ostrya is monophyletic (BS=86, PP=99). AtpB-rbcL intergenic spacer region analysis shows that Ostryopsis appeared as the most basal clade within the Coryloideae; Corylus is monophyletic(BS=98, PP=100) and placed between Carpinus-Ostrya and Ostryopsis clade; Carpinus and Ostrya formed a clade with a high support value(BS=100, PP=100). Carpinus sect. Carpinus is monophyletic, whereas sect. Distegocarpus is paraphyletic in the waxy tree. Corylus formed two subclades, but discordance at the infrageneric classification based on morphological characters. In the atpB-rbcL tree, Carpinus and Corylus taxa form a polytomy within the each clade. Results from the two data sets differ mainly in the relative position of Ostryopsis, the monophyly of Ostrya, and the relationships within the Carpinus-Ostrya clade. Further studies are needed for clarify the taxonomic position and the generic limitation.
Seed morphology of Euphorbia section Zygophyllidium and related taxa
Jin , Sun-Mi ; Park, Ki-Ryong ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 389~403
Seed morphological studies of 12 species of sect. Zygophyllidium and related Poinsettia using light and scanning electron microscopy were conducted to test the hypotheses of the sectional boundaries and species relationships. Characteristics of seeds, and the keys of identification of 12 species were presented. Seeds of 12 species were divided into 6 types based on the UPGMA tree from numerical analyses using nine seed characters. Type I, including E. uniglandulosa, is characterized by the foveolate seed with granulate testa cells. Type II, including species E. exstipulata, E. lagunensis, E. bilobata, E. hexagonoides and E. chersonesa, was recognized by the presence of inter-cellular granules among testa cells. Type III, including E. cyathophora, has a seed with acute apex, and concentric circles on the surface of testa cells. Type IV, including species of E. dentata and E. pentadactyla, has a seed with caruncle and lacking inter-cellular granules among testa cells. Type V, including E. hexagona, was characterized by the ovate seeds and lacking inter-cellular granules. Type VI, including E. eriantha and E. lacera, was recognized by the seeds with rectangular shape with caruncle. Based on the seed morphology, sect. Zygophyllidium should be defined only species with E. exstipulata, E. lagunensis, E. bilobata, E. hexagonoides and E. chersonesa. E. hexagona, traditionally included in this section, was closely related to E. dentata from Poinsettia.

Cho, Seong-Ho ; Kim, Ki-Joong ; Park, Chong-Wook ; Sun, Byung-Yun ; Chung, Myong-Gi ; Pak, Jae-Hong ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 405~431
Cuticle micromorphology of 22 species of Quercus and outgroup were examined by the SEM. Twenty-two species selected each two or three species in all section of the genus Quercus. The genus Trigonobalanus and Alnus are selected as outgroups. Ten characters of the inner surface and eight characters of the outer surface of the cuticle have been described. Some characters, such as the present of papillae, arrangement of subsidiary cell, shape of anticlinal cell wall are considered important character for infrageneric classification. A parsimony analysis of 18 characters resulted in 72 most parsimonious trees with its lengths of 66 steps. The topology obtained from the analysis showed two major lineages. Subgenus Cyclobalanopsis formed one clade by 75% and subgenus Quercus formed another clade by 57% bootstrap value. Based on the cuticle morphology, the two subgenus delimitation of Camus was supported. However, sect. Erythrobalanus and sect. Cerris formed one group, and sect. Lepidobalanus formed polytomy.
The morphology of Thalictrum L. in Korea
Park , Seong-Jun ; Park, Seon-Joo ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 433~458
This study were examined for their external morphological characters such as root, leaf, inflorescenses, flower, stamen, pistil, and fruit as to Korean Thalictrum L. and discussed taxanomic value of characters, and made out a new key. This study confirmed that specialized stems and roots type were divided into fibrous type, fibrous having a tuber type, long fusiform tuberous type, tuberoid type, rhizome type and stolon type. The stem were divided into two types based on existence and nonexistence of striate or pubescent. Leaves were usually 2-3-ternately and was divided into three types based on leaf apex, leaf base and number of lobe. Inflorescenses were divided into two type; corymb, panicle. Flower is bisexual, and don't have petal. It was divided from existence and nonexistence of calyx when it flowering. Especially, the stamens were divided from anther shape and apex shape, degree of dilation of filament, epidermic shape of filament etc., and the pistils were divided from glandular on ovary, length of carpel stipe etc.. The fruit is a achene and it was divided from achene shape, achene rib or wings, achene stipe length. This study suggest that useful characters for identifying section are degree of dilation of filament, anther shape, achene rib and wings, degree of dilation of achene. Also, roots, leaf shape, stamen and pistil shape, achene beak and achene length, achene and leaf hair appear to be useful characters for identifying species.
Spore morphology of Korean Thelypteridaceae
Moon, Su-Mi ; Sun, Byung-Yun ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 459~476
Taxonomic characteristics of spores of 17 species belonging to 6 genera of the Korean Thelypteridaceae are examined. Description of each species and key to the species are provided. Spores of Korean Thelypteridaceae are monad and monolete with bilateral symmetry. Perispore, the sporoderm of spore, was found in all the species examined. The perispores and exospores of Thelypteris japonica var. japonica, T. japonica var. glabrata and Pseudocyclosorus subochthodes are much similar to each other, but the rest of taxa examined shows diverse patterns of the surface ornamentation of perispores and exopores enough to distinguish genera and sometimes to distinguish species in some genera. Previous study reported that perispore is not easily distinguished from exospore in Cyclosorus and Leptogramma. However, three species of Cyclosorus examined here show different pattern having scabrate or verrucate exospores and cristate or echinate perispores. Leptogramma pozoi ssp. mollisima also have echinate perispore and fossulate exospore. Macrothelypteris oligophlebia var. elegans and M. viridifrons have scabrate exospore which is contrast to previous report of reticulate exospore. Thelypteris glanduligera, T. angustifrons and T. laxa show same patterns of perispore and exospore with reticulate perispore and fossulate exospore and hence cannot be distinguished by spores only.
A taxonomic study on the spikelet morphology of Korean Poa L. (Poaceae)
Jung, Su-Young ; Chung, Gyu-Young ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 477~502
Morphological characters of inflorescence, spikelet, rachilla, glume, lemma and palea about 17 taxa of Korean Poa L. were investigated to evaluate their taxonomic significances. The bulbil present or not, inflorescence shape, callus shape of lemma and surface shape of palea were thought to be the subgenus characters. The keels shapes of palea, the number of lower glume, lateral nerve shape of lemma were thought to be the section characters. The number of floret, rachilla present or not, the number of lower glume, nerve shape of glume, surface shape of lemma were thought to be the species characters. Consequently, 17 taxa of the Korean Poa L. is classified into 3 subgenus (Ochlopoa, Stenopoa, Stenopoa), 7 section(Arenariae, Ochlopoa, Homalopoa, Poa, Pandemos, Tichopoa, Stenopoa). 6 taxa, P. ullungdoensis, P. takeshimana and P. matsumurae, P. nipponica, P. radula, P. viridula, not included in the existing classification system, were suggested to their taxonomic category in infragenic rank, and P. nemoralis, had been included in section Stenopoa of subgenus Stenopoa, was proposed to move to section Poa of subgenus Poa. P. ullungdoensis, reported as new species in 1955, was grasped its taxonomic identity.
The first record of Bidens radiates var. radiates in Korea
Hong , Suk-Pyo ; Kim, Sun-Yu ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 503~507
During the systematic study of the genus Bidens L. (Asteraceae) in Korea, we found two specimens collected from Bujeon Plateau, Hamgyungnam-do, which are recognized as a new taxon (B. radiata Thill. var. radiata) for the flora of Korea. The Korean name for this taxon is newly designated as 'Sam-ip-gu-wa-ga-mak-sa-ri'. The close relative of this taxon is B. radiata Thill. var. pinnatifida (Turcz. ex DC.) Kitam., but B. radiata var. radiata can be distinguished from B. radiata var. pinnatifida by having mostly 3-parted and lanceolate lobe of leaf. The key for varieties of B. radiata is given.

The first record of Gentianopsis (Gentianaceae) in Korea: G. contorta (Royle) Ma
Ji, Seong-Jin ; Kim, Yoon-Young ; Oh, Byoung-Un ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 523~529
We confirmed an unrecorded taxon under the genus Gentianopsis (Gentianaceae) into Gentianopsis contorta (Royle) Ma, which was collected from Geumdaebong, Jeongseon-gun, Gangwon-do in the central part of Korean peninsula. This taxon was known to be distributed mainly Himalayan mountainous area such as India, Nepal and Pakistan, and also growing in China and Japan. In this study, we carried out species description based on the morphological characters, and gave the new Korean name, ‘Kko-in-yong-dam’ by the characteristics of floral morphology. In addition, some fine figures on several important characters and key to the this and relative species were provided.

Kim, Jin-Seok ; Lee , Gang-Hyeop ; Pak , Jae-Hong ; Kim, Sang-Yong ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 531~537
We report an unrecorded species of Corydalis sect. Corydalis (Fumariaceae), C. caudata (Lam.) Pers., that have been found in the central part of Korea. This species is easily recognized by its bearded calyx, upwardly curved spur, and multi-branched characteristics. We named it 'Soo-yeom-hyeon-ho-saek' as korean common name.

Im, Hyung-Tak ; Kim, Kyu-Sick ; Oh, Byeong-un ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 539~545
Distribution of Carex miyabei Franch., formerly considered as an endemic species of Japan, in Korea is verified and reported here. It is distinguished from the morphologically similar species in the same section, such as C. lasiocarpa Ehrh. var. occultans (Franch.) Kük., C. drymopila Turcz. ex Steud. var. abbreviata (Kük.) Ohwi, and C. glabrescens (Kük.) Ohwi, in having long-beaked and acutely 2-toothed perigynia which are densely covered with stout short hairs.
Two naturalized plants of Lespedeza (Leguminosae) in Korea: L. lichiyuniae & L. dauidii
Han, Jeong-Eun ; Choi, Byoung-Hee ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 547~555
Two naturalized plants of Lespedeza from Korea are reported. L. lichiyuniae T. Nemoto, H. Ohashi & T. Itoh is similar to L. cuneata (Dum. Cours.) G. Don. and L. juncea (L. .f.) Pers. in morphology, but the species differs from them by pink or purple flowers and the under surface of leaflets and cleistogamous pods with densely hairs. L. davidii Franchet is distinguished by distinctly large leaflets from the other Korean Lespedeza and by plants covered with densely tomentose hairs from the Korean species of subgenus Macrolespedeza. In Korea two plants are found on the parks or roads prepared recently.

Son, Hyun-Deok ; Kim , Dong-Hyeon ; Im, Hyoung-Tak ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 565~571
In the course of execution for Inventories and Management of Plant Resources of Korea, We found new habitats of 4 plant species which distribution ranges are obscure and/or extremely restricted. A subtropical fern distributed in Jeju-do, Woodwardia japonica (L. f.) Sm., was found in Mt. Gambang-san of Hampyeong-gun, Jeollanam-do. A saprophytic orchid, Galeola septentrionalis Reichb., was found in Mt. Ggachi-bong of Boseong-gun, Jeollanam-do. Peristrophe japonica (Thunb.) Bremek., known in Jeollanam-do, was newly found in Mt. Mudeung-san of Gwangju-si. Viburnum furcatum Blume mainly distributed in Jeju-do and Ulleung-do was found in Mt. Jabyeong-san of Gangneung-si, Gangwon-do.
A new natural habitat of Abeliophyllum distichum Nakai
Kim , Dong-Kap ; Kim, Joo-Hwan ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 573~582
We report a newly found natural habitat of Abeliophyllum distichum in mountainous slope range of Yeongdong-gun, Chungbuk Province. Abeliophyllum distichum Nakai is one of the Korean monotypic endemic species. Natural growth habitats of this species have been recorded from seven sites up to now, and all of the natural habitats are located in middle (Chungbuk Prov.) and middle west (Jeonbuk Prov.) parts of South Korea. Among the previously recorded seven natural habitats, six sites have been designated as Korean national monuments and protected with in situ conservation. New natural habitat of A. distichum is located on northwest slope of stiff hillock area beside the small stream, Seolgye-ri, Yeongdong-eup, Yeongdong-gun, Chungbuk Province. Total growing area is nearly 3,000 ㎡. It is 10-25 cm in soil depth and pH 5.0-6.5 in soil acidity in that area. And many of A. distichum are clustered with 2-5 individuals extended by stoloniferous asexual reproduction. And the total numbers of A. distichum are about 700 individuals with only typical white flowers, and the ratio between pin type and thrum type is 37% and 63%, respectively. The huge population of A. distichum is growing with Quercus mongolica-Fraxinus rhynchophylla association in a mixed forest, and it shows high affinity with Stephanandra incisa, Ligustrum obtusifolium, Euonymus alatus for. ciliatodentatus, and Smilax sieboldi.
The Paleovegetation at Dongdo of Is. Dokdo, Korea
Yoon , Soon-Ock ; Hwang, Sangill ;
Korean Journal of Plant Taxonomy, volume 38, issue 4, 2008, Pages 583~599
Dokdo, small island located in the eastern end of the Korean Peninsula, has been an uninhabited island for long time due to long distance from the land. Moreover, the steep slope of volcanic tuff at Dokdo is well drained for high permeability and Dokdo has few plain areas, swamps and very thin soil layers. In this study, pollen analysis at Dokdo was attempted on the profile of organic sandy soil for the first time in Korea owing to the marine climate environment with high humidity and precipitation including snowfalls in spite of unprofitable condition geologically or geomorphologically. While many historical, political researches have been accumulated for territorial problem of Dokdo with Japan, natural scientific researches with field work are not sufficient, and few paleoecological researches have been done. As a result of pollen analysis, the ratio of the NAP(Non-Arboreal Pollen) and spore was higher than AP(Arboreal Pollen), and the vegetation change existed by showing dramatic decrease of AP at the upper layer. AP was composed of almost Pinus, and a little Alnus, Quercus, Betula, Carpinus, Picea and Ulmus. NAP was composed of Gramineae, Compositae, Chenopodiaceae Cyperaceae, Caryophyllaceae, Liliaceae, Umbelliferae, Artemisia, Lobelia, Rumex, Polygonum. Increase of the NAP such as Gramineae, Artemisia and Chenopodiaceae, they would mostly have been transported from the other areas because agricultural activity is impossible at Dokdo. While one reason of Pinus thunbergii decrease could be regarded as environmental change, the other reason would be lumbering of pine trees by human activity which is adapted to Dokdo environment.
