Systematic study of Korean Asparagus L. based on morphology and nuclear ITS sequences
Cho, Seong-Hyun ; Kim, Young-Dong ;
Korean Journal of Plant Taxonomy, volume 42, issue 3, 2012, Pages 185~196
DOI : 10.11110/kjpt.2012.42.3.185
Morphological and geographical examinations as well as phylogenetic analyses using ITS sequences were performed for Asparagus L. in Korea. A total of five species of Asparagus were confirmed to be distributed in South Korea. The shape of cladophylls, length of pedicels, and shape of perianth were considered to be important characteristics for the identification of Koran Asparagus species. A monophyly of each species was evident in the ITS phylogenetic trees in which multiple accessions (5 to 24, depending on species) represented each of the five Korean species. A. rigidulus Nakai, once considered conspecific to A. schoberioides Kunth, formed a distinct lineage in the ITS trees. Pedicels of A. rigidulus, which is distributed mainly in coastal areas, were about two times longer than those of A. schoberioides occurring in inland areas, suggesting that they should be treated as distinct taxa.
A New species of Elsholtzia (Lamiaceae): E. byeonsanensis M. Kim

DOI : 10.11110/kjpt.2012.42.3.197
A new species, Elsholtzia byeonsanensis M. Kim is named and described from Byeonsan, Jeollabukdo Province, Korea. Molecular data confirmed that this new taxon was distinguished from other congeneric species. Elsholtzia byeonsanensis shares several characteristics (secund spikes, ovate leaves, long corolla length, etc.) with its related species E. splendens, but it is distinct from E. splendens which has a large plant, green stem color, chartaceous leaf textures, non-shiny leaf surfaces, pubescent petioles, pubescent leaf blade surfaces, pubescent bract surface, and open woodland habitats by having a small plant, purple stem color, coriaceous leaf textures, shiny leaf surfaces, glabrous petioles, glabrous leaf blade surfaces, glabrous bract surface, and marine habitats.
A New species of Viola (Violaceae): V. ulleungdoensis M. Kim & J. Lee
Lee, Jungsim ; Choi, Changhak ; Han, Kyeongsuk ; So, Soonku ; Hwang, Yong ; Kim, Muyeol ;
Korean Journal of Plant Taxonomy, volume 42, issue 3, 2012, Pages 202~206
DOI : 10.11110/kjpt.2012.42.3.202
A new species, Viola ulleungdoensis M. Kim & J. Lee is named and described from Is. Ulleung, Gyeongsangbukdo Province, Korea. Molecular data confirmed that this new taxon was distinguished from other congeneric species. The Viola ulleungdoensis shares several characteristics (acaulescent leaves, beardless lateral petals, glabrous petioles and peduncles, etc.) with its related species V. selkirkii, but is distinct from V. selkirkii which has present adventitious buds, same leaves after flowering, small leaves, and high altitude habitats by having absent adventitious buds, larger leaves after flowering, large leaves, and low altitude habitats.
First record of Hylodesmum laxum (Fabaceae) from Korea
Lee, Ji-Yeon ; Kim, Myeong Jun ; Oh, Chung-Keun ; Choi, Byoung-Hee ;
Korean Journal of Plant Taxonomy, volume 42, issue 3, 2012, Pages 207~210
DOI : 10.11110/kjpt.2012.42.3.207
Hylodesmum laxum (Candolle) H. Ohashi & R. R. Mill subsp. laxum was recorded from Korea. The species is widely distributed in S. E. Asia, but in Korea the plant was the first found in the evergreen forest of Seogwipo-si in Jeju-do. Hylodesmum H. Ohashi & R. R. Mill was raised as a separate genus recently based on Desmodium sect. Podocarpium Benth. Except for two species, all Korean species included in the former Desmodium are classified into the genus Hylodesmum. A key to and enumeration of the Korean species of Hylodesmum are provided.
First report for Platanthera brevicalcarata (Orchidaceae) in Korea
Eum, Sang Mi ; Lee, Nam Sook ;
Korean Journal of Plant Taxonomy, volume 42, issue 3, 2012, Pages 211~214
DOI : 10.11110/kjpt.2012.42.3.211
Platanthera brevicalcarata Hayata (Orchidaceae), previously known to be distributed from Taiwan to southern Japan, was found in the Jeju-do, Korea. This species is distinguished from the related taxon Platanthera chlorantha by its small plant size, white sepal with distinct one green vein, and short-cylindrical spur. The local name Young-ju-je-bi-ran is originated from the local name of Mt. Halla. The morphological characters and illustration of the species are provided with line drawing and photograph from the natural habitat.
Taxonomy of Korean Calanthe species and few of its mutants based on AFLP data
Srikanth, Krishnamoorthy ; Koo, Ja Choon ; Ku, Jajung ; Choi, Kyung ; Park, Kwang-Woo ; So, Soonku ; Choi, Yong-Gook ; Whang, Sung Soo ;

Five Korean Calanthe species, C. discolor, C. bicolor, C. sieboldii, C. reflexa, and C. aristulifera, were studied using amplified fragment length polymorphism (AFLP) to assess their taxonomic and genetic relationships. Sixteen accessions belonging to five native Calanthe spp. and mutants with yellow tepal and white lip (YW mutants) were studied. We identified 50 putative markers using AFLP analysis. The results of AMOVA showed that genetic variance was higher between species than within species. Genetic dissimilarity when compared with the rest of the species was the lowest for individuals of the YW mutants and the highest for individuals of C. reflexa. The mutants clustered outside the major group. Calanthe bicolor clustered with C. discolor, suggesting that its genetic composition is closer to that of C. discolor. Though it is suggested to have originated as a result of natural hybridization between C. sieboldii and C. discolor, introgression is likely to have occurred in the direction of C. discolor based on the data of molecular marker, clustering and genetic dissimilarity. Calanthe reflexa and C. aristulifera were genetically the most diverse of the species studied. In conclusion, the results showed that there is genetic diversity in Korean Calanthe species, that C. bicolor introgressed in the direction of C. discolor and that the YW mutants are genetically closer to C. sieboldii.
Floristic diversity assessment and vegetation analysis of Upper Siang district of eastern Himalaya in North East India

Present paper is an outcome of a four-year floristic survey work carried out in Upper Siang district of eastern Himalayan region in India which is also recognized as one of the 39 known 'Biodiversity Hot-Spots' of the world. We present here with a vegetation analysis of this area along with a checklist of 1,003 taxa belonging to 110 families, 529 genera, 994 species, 1 subspecies and 8 varieties of the angiosperms. Besides, one new species, 3 new records to India and 82 endemic species were also recorded. The diversity of herbs and shrubs were found higher than the tree species. Orchidaceae was found the most dominant family followed by Poaceae and Fabaceae. Many threatened plants have also been reported from the area. However, rapid urbanization and Jhum cultivation are imposing direct threat to the natural vegetation. We suggest some conservation measures that could help protecting this natural heritage.
