  • Author has studied and reported on taxonomy of Korean sedges, using gross morphology, anatomy and epidermal patterns of the leaf blades(1969, 1971, 1973, 1974). This paper is the 6th report of epidermal patterns of leaf blade on sedges and includes 5 genera, Eriophorum, Fuirena, Kobresia, Rhynchospora and Scirpus. The author proposed to find epidermal patterns of leaf blades as an important taxonomic characteristic of sedges classification. The result of this study, the elements of leaf epidermis, subsidal cells, silica body, cell wall of long cell, prickles, and arrangement of the elements are considered to be significant characteristics for the identification and classification of sedge.

  • The purpose of this study is to review the taxonomic position of Taxus cuspidata var. latifolia endemic to Ulleung Island with related taxa T. cuspidata var. cuspidata, T. caespitosa, and T. cuspidata var. nana based on external morphological characters and DNA barcoding study. T. cuspidata var. latifolia was similar to T. cuspidata var. cuspidata in the arbor, straight trunk, and symmetric arrangement of leaf. But the unique differences between T. cuspidata var. latifolia and T. cuspidata var. cuspidata were leaf size and the exposure of seed from aril. Additionally, sequences of four chloroplast DNA regions including matK, rbcL, trnL intron and trnL-trnF spacer regions were analyzed. Korean Taxus species and their related taxon T. cuspidata var. nana were strongly supported as a monophyletic group in neighbor-joining analysis. Taxus cuspidata var. latifolia showed 100% sequence identity to related taxa. Korean endemic T. caespitosa is also distinguishable from related taxa by prostrate stems and spiral arrangement of leaf. The examinations of external morphology and DNA barcoding study suggest that the taxonomic position of T. cuspidata var. latifolia should be maintained as a variety of T. cuspidata.

  • A taxonomic study of the family Antedonidae is presented. The specimens were collected in the coastal seas of Korea from 1970 to 1994 and deposited in the Natural History Museum of Ewha Womans University. Four species, Heliometra glacialis maxima, Antedon serrata, Antedon parviflora and Andrometra psyche of the subfamilies Heliometrinae and Antedoninae were identified, of which 3 species, Antedon serrata, Antedon parviflora and Andrometra psyche in the subfamily Antedoninae are new to Korea. The subfamily Antedoninae is reported for the first time in Korea.

  • A taxonomic study on marine sponges was conducted with materials collected from Gageodo Island, Korea, from August 1999 to July 2001 by SCUBA diving. Among them, Phorbas gukhulensis n. sp. is new to science. Phorbas gukhulensis n. sp. is similar to P. fitictius Pulitzer-Finali from which it differs in spicule size and growth form.

  • 미국산 사초속 식물의 잎의 표피형에 대한 조사로서 6 Sect., 6 Species에 대해 주사현미경을 사용하여 표피형을 조사하였다. 표피형의 구성요소인 숨구멍(Stomata), 세포벽(Cell wall), 유두돌기(Papillae), 가시돌기 (Prickle), 납질(Waxy)등의 모양을 조사하였다. 표피형 구성세포의 특징이 종류에 따라 차이가 있어 사초속 식물의 감별 및 분류에 좋은 형질이 될수가 있다고 보는 바이다.

  • Taxonomic study for the comantulid crinoids collected from Korea Strait was conducted. A oligophreatan species, Parametra orion (A. H. Clark, 1907) belonging to the family Thalassometridae, was identified and turned out to be new to the Korean fauna. The family Thalassometridae is newly reported in Korea.
