Palynological contributions to the taxonomy of family Oleaceae, with special empahsis on genus Forsythia (tribe Forsytheae)
Lee, Sang-Tae ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 175~181
Traditionally, the Oleaceae has been divided into subfamilies Oleoideae and Jasminoideae. In the present paper, the taxonomical results so far made on the family were reviewed on the basis of palynology. The subfamilial classification is not well supported palynoligically, because both Myxopyrum of Jasminoideae and Comoranthus of Oleoideae having foveolate surface are well distinguished from the rest of the family having reticulate surface. The recent subfamily Nyctanthoideae (Takhtajan, 1977) including the monotypic Nyctanthus, was suggested to be included within the Jasminoideae although its closest relative on the palynological basis is different from that on the molecular basis. Tribal classification systems of the Jasminoideae are not well supported palynologically on the basis of surface character: presence or absence of bands on the mural ridge surface of the reticulum. On the basis of palynology, tribe Forsythiae including Abeliophyllum, Fontanesia, and Forsythia is monophyletic, and Fontanesia is well distinguished from the rest two. Korean species of Forsythia is divided into two: Forsythia koreana group and F. ovata-nakaii-saxatilis group. Recent discovery of F. saxatilis at a locality of F. ovata raised a question if the distinction between the two species on the basis of hairiness would be right. In the recent molecular studies, F. saxatilis var. lanceolata seems to be identified as F. saxatilis. Molecular studies showed that F. saxatilis (seemingly var. lanceolata or var. pilosa) is close to F. koreana. The fact in which the molecular result showed a close relationship between F. saxatilis varieties and F. koreana, is controversial to the result by floral and vegetative morphology. An intensive taxonomic study of these taxa would be needed.

As a part of the on-going effort to conserve endangered Scrophularia takesimensis Nakai in Korea, its genetic structure and diversity from 3 population, consisted of 14 subpopulations in Ulleung Island were analyzed using RAPD band patterns. Out of 60 primers tested, 33 generated amplified bands with its genome, including 149 polymorphic and 67 monomorphic bands. The highest number (146) was found in northern population, especially, 64 in HY subpopulation; the smallest (40) in eastern population. An examination of its genetic structure with AMOVA revealed that about 60% of all variations could be assigned to among subpopulations within populations. Population differentiation among populations and subpopulations is seriously going now because of habitat fragmentation due to human activities, such as road and small port construction. Although the habitats of S. takesimensis in Ulleung Island, Korea are disappeared at an alarming rate, significant levels of genetic variation still exist at species level, and population level, especially northern population. Therefore, three conservation strategies should be needed urgently; 1) preservation of populations as it stands, 2) establishment of recovery plan to connect population and subpopulations genetically, and 3) long-term monitoring.

Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 194~201
In order to acquire information on chloroplast DNA markers to evaluate the genetic diversity of evergreen broad leaved plants, we investigated the intraspecific variation of cpDNA in eight non-coding regions of nine species commonly distributed in East Asia. Although no variations were detected in psbA-trnH, rpoB-trnC, rpl16 and atpB-rbcL regions, a relatively large amount of intraspecific variations was detected in the psbC-trnS, rps16 and trnL-F regions. These results suggested that these three cpDNA markers are suitable to assess genetic diversity of the species investigated in this study. In contrast, intraspecific variations were detected in seven taxa except Hedera rhombea and Neolitsea aciculata. Neolitsea sericea and the taxa of Quercus had many polymorphic sites.

Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 202~208
The present study was focused on the careful investigation of Glechoma longituba flowers collected from four populations in Korea to clarify their precise sexual systems. All floral characters of this taxon were examined by using a stereo microscopy. The nutlet size and production were compared between two distinct morphs (i.e., hermaphrodites and females), and pollen viability test of hermaphrodite and intermediate phenotype (i.e., individuals with a mixture of females and perfect flowers) was also observed by light microscopy (LM). All of the investigated floral characters of G. longituba are significantly different from one sexual morph to another. Hermaphroditic plants were larger than the female ones in corolla width and length, calyx length, filament length, anther length, and style length (all P < 0.0001, respectively). However, the nutlet width of the female plants was larger than those of the hermaphrodites (P = 0.013). Nutlet production of females was higher than hermaphrodites in Na-Ju population [H (Hermaphrodite): ca. 17.76%, F (Female): ca. 37.45%], but in Mun- San population was no significant difference between these sexual morphs (H: ca. 57.52%, F: ca. 53.16%). We have found significant differences between the fertile pollen grain of hermaphrodite and sterile pollen grain of intermediate phenotype based on pollen size and viability. The results of the present study suggest that compensation (flower size dimorphism, seed set, and pollen viability) is one of the main mechanisms in order to maintain female plants in gynodioecious G. longituba.

The taxonomy of the umbelliferous species Angelica amurensis and its allies was reviewed on the basis of molecular phylogenies derived from sequences of nuclear ribosomal DNA internal transcribed spacer (ITS) regions. Strict consensus of six minimal length 119-step trees derived from equally weighted maximum parsimony analysis of combined nuclear rDNA ITS1 and ITS2 sequences from 29 accessions of Angelica and outgroups indicated that Angelica purpuraefolia, known to be endemic to Korea, is the same species as A. amurensis. Comparisons of sequence pairs across both spacer regions revealed identity or 1-2 bp differences between A. purpuraefolia and A. amurensis. These results indicated that the two taxa are not distinguished taxonomically. Also, nuclear rDNA ITS regions are discussed as potential barcoding loci for identifying Korean Angelica.

Various aneuploidy and polyploidy have been reported in the genus Aconitum L. (ca. 300 species worldwide, Ranunculaceae), and there is a demonstrated association between major lineage diversification and polyploidy. This study reports chromosome counts of eight Aconitum from Korea, including the first counts for A. japonicum Thunb. subsp. napiforme (H. L
v. & Vaniot) Kadota (2n = 32) and A. longecassidatum Nakai (2n = 16). The study also includes chromosome numbers for two taxa on the Critically Endangered species list in Korea. Among Korean native species, chromosome numbers in Aconitum subgenus Aconitum range from 2n = 16 to 2n = 64 with diverse levels of polyploidy (2x, 4x, and 8x), whereas Aconitum subg. Lycoctonum exhibits only diploids (2n = 16). Greater chromosome number diversity in subg. Aconitum than subg. Lycoctonum might explain higher species diversity within the former subgenus (more than 250 species worldwide). Investigating chromosome number diversity of Aconitum in a phylogenetic framework will be a critical step to understand species richness of the genus.
Morphological multivariate analyses of Isodon excisus complex (Lamiaceae) in Korea
Kim, Sang-Tae ; Ma, Youn-Ju ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 223~229
The taxonomy of the Isodon excisus complex has been ambiguous and problematic because the morphological characters, especially characters related to the leaf distinguishing subgroups of the complex in the original descriptions, are variable. To elucidate the taxonomic structure of the I. excisus complex in Korea, 34 characters were measured from 70 OTUs representing different locations and analyzed by principal component analysis (PCA). The analysis showed that principle component axis 1, 2, 3 (PC1, PC2, PC3) represents 52.0% of the total variance and characters showing high loading values for PC1 were leaf shape, density of non-glandular hairs on the lower surface of the leaf, and characters related to the teeth of the leaf. The length of apical tooth and the angle between two widest points of the leaf were highly correlated to PC2 and PC3, respectively. Three-dimensional scatter plotting of OTUs for PC1, PC2, and PC3 axis showed that the areas of previously recognized three subgroups of I. excisus completely overlapped. Our result supported that just one taxon, I. excisus var. excisus, should be recognized in the complex at the variety level.
Unrecorded liverwort species from Korean flora: Alobiellopsis parvifolius (Cephaloziaceae), Calypogeia japonica (Calypogeiaceae), Hattoria yakushimensis (Lophoziaceae), Nardia subclavata (Solenostomataceae)
Choi, Seung-Se ; Bakalin, Vadim A. ; Kim, Chul-Hwan ; Sun, Byung-Yun ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 230~234
While preparing a floristic study of Korean hepatics, we discovered the 4 unrecorded species Alobiellopsis parvifolius, Calypogeia japonica, Hattoria yakushimensis and Nardia subclavata. A. parvifolius is often confused with Solenostoma fusiforme (Steph.) Amak. in appearance, but the former differs by occasional presence of underleaves and a large hyaline outer cells of stem. C. japonica is similar to C. tosana (Steph.) Steph. The former, however, is separated from the latter by 2-3 biconcentric oil-bodies per cell compared to 3-5 grape oilbodies per cell. H. yakushimensis is a monotypic genus based on a Japanese species. This genus is characterized by unlobed, closely imbricate leaves with margins distinctly incurved and usually pigmented with a reddish purple color. N. subclavata is similar to N. assamica (Mitt.) Amakawa in large underleaves and globular oil-bodies. The former, however, is separated from the latter by convex trigones versus concave trigones, smooth cuticles versus smooth to verrucose cuticles, and oil-bodies occurring in each cell versus occurring in approximately half or fewer leaf cells.

Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 235~241
Five unrecorded species (Oedipodium griffithianum, Myurella tenerrima, Trachypus bicolor, Coscinodon humilis, Meteorium miquelianum subsp. atrovariegatum) with one unrecorded family and two unrecorded genera, were reported as new to the Korean moss flora. The monotypic family Oedipodiaceae consisting of a single genus and single species was distinguished from Splachnaceae by small plants that were 10 mm in length simple or sometimes branched, obovate-spathulate to
orbicular, costa ending below the apex and entire margins except for the lower long-ciliate portion The species was first found at the top of the Mt. Seorak at an altitude of 1708 m. The two genera, Myurella and Coscinodon were found in the Korean Peninsula. Myurella tenerrima (Theliaceae) was found around the top of Jung-bong on Mt. Jiri. It was mixed with other mosses in the crevices of rocks in the alpine regions. The species is similar to M. sibirica, yet it can be distinguished by the position of papilla in the median laminal cells. Coscinodon humilis (Grimmiaceae) were found on the ridge of Mt. Gaya. C. humilis has a variety of hyaline apex according to leaf position and forms a capsule so it can be distinguished by family. Trachypus bicolor and Meteorium miquelianum subsp. atrovariegatum are unrecorded species. T. bicolor (Trachypodaceae) were found on the ridge of Mt. Gaya. T. bicolor is similar to T. humilis but distinguished by the costal lengths of the leaves. M. miquelianum subsp. atrovariegatum (Meteoriaceae) was found in Gageo-do. This species was distinguished by the plant form and morphology of stem leaves in the same genus.
Sciaphila nana Blume (Triuridaceae) : Unrecorded species from Korean flora
Yim, Eun-Young ; Kim, Moon-Hong ; Song, Gwan-Pil ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 242~245
In this study, we described and illustrated an unrecorded species from the Korean flora, Sciaphila nana Blume, which is included in the order Pandanales and the family Triuridaceae. This taxon was found at Mul Oreum in Namwon-eup, Seogwipo-si, Jeju Special Self-Governing Province for the first time in Korea. The order Pandanales can be distinguished from the order Liliales by the anomocytic or tetracytic stomata and syncarpous or apocarpous gynoecia of the Pandanales. The family Triuridaceae and the other four taxa in the Pandanales, Cyclanthaceae, Pandanaceae, Stemonaceae, and Velloziaceae, are easily distinguished because the Triuridaceae are microtrophic herbs with scaly leaves. S. nana has a subulate style with a glabrous apex, ovate to narrow ovate leaves and bracts, male perianth segments with a knob-like structure at the apex, and a dimorphic perianth. Therefore, it is easily distinguished from S. tenella, S. multiflora, S. secundiflora, S. thaidanica, S. ramosa, and S. arfakiana.

So, Ji-Hyeon ; Kim, Myoung-Jun ; Lee, Nam-Sook ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 246~248
Triadenum breviflorum (Wallich ex Dyer) Y. Kimura in Nakai & Honda (Hypericaceae), previously known only in northeast India, China and Taiwan, was found in a few wetlands of Jeju Island in 2008. Additionally, some images online of T. breviflorum suggest that it exists in other places on the Korean peninsula but that it has been misidentified as Triadenum japonicum. This species is distinguished from the latter by white petals, inflorescence from nodes 6-11, linear to narrowly elliptic leaves, and an attenuated base. The local name Huin-kkot-mul-go-chu-na-mul implies a white flower rather than the flesh-pink color of T. japonicum. The morphological characteristics of the species are provided with photographs of the habitat.

Kim, Chan-Soo ; Kim, Soo-Young ; Byun, Gwang-Ok ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 249~252
Scutellaria tuberifera C. Y. Wu & C. Chen belonging to Lamiaceae, a species previously unrecorded for Korean flora, was collected streamside in the Andeok valley of Seogwipo-Si, on Jeju island. This species can be distinguished from others of Scutellaria from Korea by having rhizomes with leafless and branching stolons at the nodes, globose to ovoid tubers 5-7 mm in diameter at the terminal parts, and stems densely spreading pilose. Photos of the habit and illustration are provided.
A newly recorded naturalized species in Korea: Prunus speciosa (Koidz.) Nakai (Rosaceae, Prunoideae)
Kim, Chan-Soo ; Moon, Myung-Ok ; Kim, Soo-Young ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 253~258
Prunus speciosa (Koidz.) Nakai belonging to Prunoideae of Rosaceae, a species previously unrecorded in Korean flora, is described. Prunus speciosa (Koidz.) Nakai is similar to Prunus sargentii Rehder and Prunus jamasakura Siebold ex Koidz., but different because it has toothed lobes of calyx tubes with the apex of leaf serrations aristate. This species is naturalized widely in the eastern parts of Jeju Island but is endemic to Japan.
Taxonomic status of three taxa of Elsholtzia (E. hallasanensis, E. springia, and E. splendens var. fasciflora) (Lamiaceae) based on molecular data
Lee, Chang-Shook ; Hwang, Kung-Ae ; Kim, Jin-Ok ; Suh, Hyoung-Min ; Lee, Nam-Sook ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 259~266
Elsholtzia hallasanensis, E. springia, and E. splendens var. fasciflora (Lamiaceae) were reported recently as new species or new varieties of E. splendens according to their morphological characteristics. To reappraise the taxonomic status of these additional taxa and to determine the relationships between all Korean Elsholtzia taxa except E. saxatilis, which is distributed in North Korea, molecular studies based on the nrDNA (ITS) and cpDNA (rpl16, and trnH-psbA) sequences of seven taxa of Elsholtzia and one outgroup were carried out. The molecular data support that E. angustifolia and E. minima are distinct species from E. splendens and E. ciliata, respectively, because they have several private marker genes and show monophyly. The molecular data also support that E. splendens has a very close taxonomic relationship with both E. hallasanensis and E. springia. We found that E. splendens var. fasciflora, with multiple inflorescence, was based on several private marker genes and on the monophyly of its trees, suggesting that it can be considered as a variety. Elsholtzia springia, with the same sequences and the same morphological characteristics with E. hallasanensis after transplanting, should be treated as a synonym of E. hallasanensis. Moreover, we consider the taxonomic status of E. hallasanensis as E. splendens var. hallasanensis (Y. Lee) N.S. Lee & C.S. Lee, stat. nov.

Choi, Byoung-Hee ; Endo, Yasuhiko ; Zhu, Xiang-Yun ;
Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 267~270
A new species of Hedysarum (Fabaceae, Hedysareae) was found in Tibet, China. This new species, Hedysarum hirtifoliolum, belongs to sect. Hedysarum and is readily distinguishable in having greenish yellow flowers, pubescent above surface of leaflets and transversely obovate loments. So far, it is collected from only one locality in Tibet.

Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 271~279
The morphological characteristics of the Korean Scopolia japonica Maxim., commonly known as 'Mi-chi-gwang-i-pul' in Korean, were re-evaluated in comparison with results from previous research, while the distribution map was formulated according to existing flora and voucher specimens. The result of the re-evaluation has shown that there are some distinctive discrepancies compared to the previous reports of some characteristics such as the color of the basal stem, numbers of lateral veins, apex shape of calyx and corolla including the color of corolla. The Korean Scopolia japonica Maxim is found throughout Korea except Jeju-do province. The intra-specific species such as S. parviflora (Dunn.) Nakai, S. lutescens Y.N. Lee and S. kwangdokensis Y.N. Lee were treated as synonyms of S. japonica Maxim. in this research.

Korean Journal of Plant Taxonomy, volume 41, issue 3, 2011, Pages 280~286
The natural habitats and distribution of five rare plants were recently discovered in Korea. Salomonia oblongifolia DC., which grows in mountain wetlands, was found in Gijang-gun, Busan, Gokseong-gun, Jeollanamdo, and Shinan-gun, Jeollanam-do. Glaux maritima var. obtusifolia Fernald, which grows along the coast, was found in Yangyang-gun, Gangwon-do, Pohang-si, Gyeongsangbuk-do and Buk-gu, Ulsan. Tillaea aquatica L. and Limosella aquatica L., which was previously not known to be present in Korea, were discovered in Gijanggun, Busan for the first time. Apocynum lancifolium Russanov, which has a narrow distribution range in Korea, was also found in Samcheok-si, Gangwon-do, Ansan-si, Gyeonggi-do, Siheung-si, Gyeonggi-do, Jung-gu, Incheon, Yeongdeok-gun, Gyeongsangbuk-do and Shinan-gun, Jeollanam-do.

The objective of this study was to discuss the characteristics of the moss flora of Mt. Deogyu located on the border of the Jeonbuk and Kyungnam provinces in Korea. A total of 21 field surveys were carried out at various sites in the mountain area from August 2007 to September 2008. All the collected materials were processed into voucher specimens and were currently deposited in the herbarium at Chonbuk National University (JNU). In this study, we collected and identified 158 moss taxa, which included 156 species, 1 subsp. and 1 var. of 96 genera and 37 families. Unconfirmed taxa in this study, but previously recorded, belonged to 25 taxa, which included 13 families, 19 genera and 25 species. In addition, 183 taxa were found on Mt. Dreogyu, which belonged to 37 families, 101 genera, 1 subsp. and 1 var. The habitat of each collection was examined and the classification system of Ignatov et al. (2006) was used. New vernacular names of 6 families and 11 genera were then determined. Six species, formerly thought be only in North Korea, were shown to be present on Mt. Deogyu, which included Bucklandiella laeta, Anomobryum filiforme var. concinnatum, Herzogiella turfacea, Brachythecium rutabulum, Eurhynchium angustirete and Campylidium hispidulum.
