A new species of Corydalis sect. Corydalis (Fumariaceae), Corydalis cornupetala Y.H. Kim et J.H. Jeong is described from Gyeongsan-si, Gyeongsangbuk-do in Korea. This new species is distinguished from the other species of the sect. Corydalis by some flower characters such as, purplish white petal with two dark stripes and horn-shaped apex of outer petal. The linear leaflets of C. cornupetala are similar to the lineariloba type of C remota Fisch. ex Max. or C. namdoensis B.U. Oh et J.G. Kim, but much longer and narrower. The linear or lanceolate bract of C. cornupetala is also distinctive from the elliptical shape of C. remota and C. namdoensis.

In order to estimate the genetic relationships among four taxa of Korean Symplocaceae and their regional populations, RAPDs analysis was performed. The length of the amplified DNA fragments ranged from 150 to 1,900 bp. Ninety-two RAPD bands were scored for 11 primers and the genetic distance was calculated with by Nei-Li's genetic dissimilarity. Deciduous and evergreen groups were clearly separated in the UPGMA analysis. Symplocos coreana was clustered as a distinct group, and S. sawafutagi and S. tanakana were also clustered at specific level, respectively. The RAPD data was useful to cognize the genetic variation and to iscuss the relationships among Korean Symplocaceae

A comparative micromorphological study was examined on the leaves of the genus Glechoma and related genera (Nepetinae, Lamiaceae) by scanning electron microscopy (SEM) in order to evaluate their significance in the taxonomy. The leaves of taxa Marmoritis, Nepeta sect. Glechomanthe, G. hederacea var. longituba (Korea) are revealed amphistomatic type, while the remnants of taxa had hypostomatic type. The size range of the guard cells is 12.50-28.75 × 9.17-21.25 μm: the smallest one was found in M. pharicus (12.50-15.83 × 9.17-11.25 μm), while the largest one was measured to G. hederacea var. longituba (Korea: 28.75-28.88 × 21.25-21.38 μm). The stomatal type of genera Agastache, Dracocephalum was mostly diacytic, however for the rest rarely together with anisocytic and anomocytic, except G. hederaca var. longituba (Korea), Meehania urticifolia by having combined with diacytic and anomocytic. The shapes of epidermal cells are differ from in abaxial and adaxial side, and dived with two types (e.g., platelet, stripe pattern). Five types (three glandular, two non-glandular hairs) of trichomes are distributed in leaves. Among trichomes, long and stalk capitates glandular trichome, subsessile glands are different from studied taxa so that leaf micromorphological characters are significance features in the taxonomy.

The morphological characters for 4 taxa of Korean S ymplocaceae were exarnined. Based on morphological examination, numerical analysis was performed to clarify the taxonomic relationships among the taxa. It was found that epidermal characters of leaves, cellular deposition of petals, cellular boundary of petioles, growth of stigmas and pollen grains and their surfaces were useful diagonostic characters. From the results of PCA analysis, four taxa were grouped as species clusters including each populations. Four species of Symplocos were clustered as species groups with clear delirnitation. Morphological, numerical, and palynological analyses supported the previous morphological studies on this family.

For 20 taxa of Korean Allium, including 16 species and 5 varieties, examined were morphological characters (i.e. sexuality, structure and shape of underground part, types and growing patterns of leaf and scape, and shapes of perianth, filament and pistil). The specialization and the evolutionary trends of taxonomic characters were inferred from morphological examination. Taxonomic relationships and system of Korean Allium were also studied. The characters showing evolutionary trends were the structure and shape of underground part including rhizome and bulb, leaf, scape, inflorescens, filament and ovary. It seemed that thin and short rhizome developed from thick and long one, and the membranous simple bulb tunic evolved into fibrous reticulate one. The presence of hyaline sheath in A. monanthum of sect. Microscordum was apomorphic. Both angular leaf blade with 2-rowed vascular bundle and flat blade with 1-rowed vascular bundle were developed from terete one with 2-rowed vascular bundle. The base of filament have differentiated from entire to toothed, and 2-ovuled ovary as well as erect scape before flowering was plesiomorphic type. In addition, sexuality, structure of underground part, the presence of hyaline sheath and cross-section structure of leaf were taxonomic characters with the level of the subgenus in this genus. Shape of rhizome, bulb, leaf, scape and pedicel discriminated each section from other ones in the subgenera easily. The shape and arrangement of perianth and filaments were the diagnostic characters for species level along with shape of ovary and stigma.

Korea national arboretum has worked with the plant taxonomic society of Korea to make the first fully electronic floristic checklist in Korea. The result is an ever-expanding online plant name index containing scientifically authorative, up-to-date information on the approximately 7,000 taxa including cultivars. With 37 contributing taxonomists, KPNI is the largest collaborative research projects ever assembled in Korea. A comprehensive database model for the taxonomic data from literature and other sources is presented, which was devised for the Korea National Plant Index database project (KPNI). Gwangreung database model is based on an approach using entity-relationsip diagram. It encompasses taxa of all ranks, nothotaxa and hybrid formulae, cultivars, full synonymy, basionyms, Korean name, and other nomenclatural information. Ths paper presents an analysis of KPNI work processes and an overview how we are approaching the construction of Gwangreung databaese model. It can help the system engineers of other biological information systems to develop their database based on the accurate and integrative taxonomic database.
