A taxonomic study on the Fuirena, Kobresia, and Scleria of Korea(Cyperaceae)
Oh, Yong Cha ; Lee, Chang Shook ; Lee, Jae Kyung ;
Korean Journal of Plant Taxonomy, volume 32, issue 4, 2002, Pages 363~382
Morphological characters of three taxa belonging to three genera (Fuirena, Kobresia, and Scleria) in Korean Cyperaceae were reexamined. The anatomical patterns of stems and leaves, and epidermal patterns of achenes and leaves were investigated by a scanning electron microscope (SEM) and a light microscope (LM). Based upon the results, the scientific and Korean names, which have not been clearly established, were reviewed. Morphological characters such as length and width of stem, leaf, bract, scale, achene, and shape of achene, spikelet, style base, scale, perianth, and anatomical characters such as shape of stem and leaf, shape of achene epidermal cell and silica body of leaf, size and frequency of stomatal complex, presence of bulliform cell were useful for an identification of the three taxa.

RAPD analyses were compared for 17 taxa of Korean Iris including the subgenus Sisyrinchium and Belamcanda. Eighty scorable RAPD markers were formed from the PCR reactions using 10 random oligoprimers. In this systematic analyses which used neighbor-joining methods including bootstrapping analyses with genetic coefficients, the Korean Iris were divided into three subgenera (Limniris, Crossiris, Pardanthopsis), or two genera (Limniris, Pardanthopsis). The molecular data agree with the previous classification system that recognized two sections and six series for the subgenus Limniris because the subgenus is comprised of four clades in the RAPD analyses. According to the molecula data, the series Chinensis should be divided into two groups. The minutoaurea group is composed of I. koreana, I. odaesanensis, and I. minitoaurea, while the rossi group is comprised of two varieties of I. rossi. The series Tripetalae is closely allied with the series Sibiricae, whereas the series Ensatae is recognized as a sister group to the series Ruthencae. The molecular phylogeny, which was based on RAPD analysis, for the most part agreed with the data proposed by previous authors. This is because the basis of morphological and ITS sequence data suggests that the RAPD markers should be very useful in addressing phylogenetic questions about the genus Iris.
A taxonomic study of Viola section Chamaemelanium in Korea-based on morphological characters
Whang, Sung Soo ;
Korean Journal of Plant Taxonomy, volume 32, issue 4, 2002, Pages 397~416
A taxonomic study of Viola section Chamaemelanium in Korea, based on morphological characters, was conducted with light microscopy and scanning electron microscopy. Two species, V. orientalis W. Becker and V. brevistipulata (Fr. et Sav.) W. Becker, are recognized by rhizome and cauline habits, trichomes on the ovary and the shape and beards of stigmas. The latter can be split further into three varieties, var. brevistipulata, var. minor Nakai and var. laciniata (Boiss.) W. Becker, according to the leaf morphology in particular. Viola brevistipulata var. laciniata has the most tooth number, and its teeth are irregular erose but the other two varieties are regular sinuate or serrate. As for the size of leaves, V. brevistipular var. brevistipulata is the largest but V. brevistipulata var. minor is the smallest among the varities. Of them, V. brevistipulata var. laciniata is newly recorded in Korea. It was also revealed that both development and arrangement of the beards developed on the ovary and stigma were particularly diagnostic in the identification of the Viola section Chamaemelanium species.
A taxonomic review of Korean Polygonatum (Ruscaceae)
Jang, Chang-Gee ;
Korean Journal of Plant Taxonomy, volume 32, issue 4, 2002, Pages 417~447
Polygonatum taxa of Korea were classified as two sections, three series and 14 species and 2 varieties and reviewed taxonomically. Among the examined taxa, endemics in Korea were recorded as two species; P. grandicaule Y. S. Kim, B. U. Oh & C. G. Jang and P. infundiflorum Y. S. Kim, B. U. Oh & C. G. Jang. The habitat of Korean unrecorded species, P. acuminatifolium Kom. and P. odoratum var. odoratum were confirmed in this study. Keys to the sections, series and species including description of each taxon were provided here.
A taxonomic review of Korean Asparagales and Liliales (Liliopsida)
Jang, Chang-Gee ; Pfosser, Martin F. ;
Korean Journal of Plant Taxonomy, volume 32, issue 4, 2002, Pages 449~465
A systematic review for Korean Liliopsida was carried out with rbcL and atpB sequence data. Congruent phylogenetic trees were obtained from two different data sets. Korean Liliopsida consists of the three orders, Asparagales, Liliales, and Dioscoreales sensu Dahlgren et al. Members of Dioscoreales were used as an outgroup for inferring relationships among Asparagales and Liliales in the molecular studies. Iridaceae showed close relationship to Asparagales both in the rbcL and atpB sequence trees rather than to Liliales. Family Nartheciaceae (previously included within Melanthiaceae s. lat.) appeared as a paraphyletic assemblage basal within Liliales, but did not show relationships to other orders. Genera of Ruscaceae (previously Convallariaceae) like Disporum, Clintonia, and Streptopus had to be transferred to Colchicaceae, Liliaceae, and Calochortaceae, respectively. A revised list of families for Korean members of Liliopsida is suggested.
Development of Female Gametophyte of Six Species of Corydalis (Fumariaceae)
Oh, Byoung-Un ; Jang, Chang-Gee ;
Korean Journal of Plant Taxonomy, volume 32, issue 4, 2002, Pages 467~480
The development of the female gametophyte of Corydalis albipetala, C. ambigua, C. filistipes, C. nobilis, C. solida, C. ophiocarpa have been comparatively investigated using laser scanning confocal microscope (LSCM) and light microscope. An archesporium was originated from one of the outmost parietal cells beneath the one-layered epidermis of protuberant nucellus, and acted directly as a megaspore mother cell (MMC). These species had linear tetrads after successional meiotic division during the megasprogenesis. A functional megasprore developed from one of the tetrad in the chalazal end, and the rest three being degenerated. The developmental type of the female gametophyte was monosporic in accordance with the Polygonum type. Prior to anthesis the female gametophyte was organized. So mature embryo sac was comprised a three-celled egg apparatus, three large antipodals were developed from the apex of each antipodal cell, and extended toward micropylar end to be contacted with egg apparatus. Two synergids were usually observed as degenerated condition, and in this time the apices of antipodal haustoria were connected with the degenerated synergids. The developmental characteristics of seven-nucleate female gametophytes were common in all the species investigated. But the shape of mature embryo sac was ovoidal in C. albipetala, C. filistipes, C. ophiocarpa and C. solida, reflexed in C. ambigua, and rather flattened ovoidal in C. nobilis. Also, the type of megasporangium was anatropous in all the species except C. ambigua with campylotropous ovule.
Unrecorded fern species from Korean flora: Thelypteris interrupta (Thelypteridaceae) and Dryopteris subexaltata (Dryopteridaceae)

Unrecorded fern species of Korean flora, Thelypteris interrupta (Willd.) K. Iwats. (Thelypteridaceae) and Dryopteris subexaltata (H. Christ) C. Chr. (Dryopteridaceae), were collected from Jeju island off the south coast of Korean peninsula and reported here. T. interrupta is most similar to T. acuminata (Houtt.) C. V. Morton in morphology, however, the two species are readily distinguishable by the plant color including rhizome, stipe base and spore, and the presence of glandular hair as well as the distribution pattern of sorus on lower leaf surface. D. subexaltata is also well distinguishable from its relatives, D. sparsa (D. Don) Kuntze, D. sabaei (Franch. & Sav.) C. Chr., and D. yakusilvicola Sa. Kurata by the presence of proliferation, shape of pinnae, distribution pattern of sori on lower leaf surface, and shape of indusium.
