While conducting a floristic study of Korean hepatics, we discovered two unrecorded species, which were collected from wind holes near the Donggang River, Korea. Mannia fragrans (Balb.) Frye & L. Clark and Mannia androgyna (L.) A. Evans are hereby reported for the first time in Korea. M. androgyna is characterized by pale grayish oil bodies in both the aerenchyma and basal tissue, and saccate spores with a conspicuous proximal disc. M. fragrans is characterized by a gynoecial segment with a whitish apical brush of scales, a commonly aromatic smell, and areolate spores with a conspicuous proximal disc. Two unrecorded species are described and illustrated based on Korean material.

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 oil-bodies 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.

This study presents a survey of the bryophytes of evergreen broad-leaved forest near Baekyaki Oreum in Gujwa-Seongsan Gotjawal in the eastern part of Jejudo Island, Korea. A total of 53 taxa belonging to Bryophyta (11 families 26 genera 39 species) and Marchantiophyta (9 families, 9 genera 14 species) were determined, and the liverwort index was found to be 26.4%. The predominant life-form was the mat type. The rates of bryophytes dominating at mesic to hygric sites were higher than those of bryophytes, which were mainly observed in xeric habitats. These values indicate that the forest areas in this study area have a high density level. Upon an investigation of the substrates, bryophytes on rocks were most diverse. It was also found that volcanic rock masses of various sizes lay scattered over the study area and offer numerous micro-habitats for bryophytes. This is related to the characteristics of Gotjawal. We consider that more detailed studies should be conducted on regional scales to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests of Jejudo Island.

This study presents a survey of bryophytes in a subtropical forest of Nabeup-ri, known as Geumsan Park, located at Aewol Gotjawal in the northwestern part of Jejudo Island, Korea. A total of 63 taxa belonging to Bryophyta (22 families 37 genera 44 species), Marchantiophyta (7 families 11 genera 18 species), and Anthocerotophyta (1 family 1 genus 1 species) were determined, and the liverwort index was 30.2%. The predominant life form was the mat form. The rates of bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that such forests are widespread in this study area. Moreover, the rock was the substrate type, which plays a major role in providing micro-habitats for bryophytes. We suggest that more detailed studies of the bryophyte flora should be conducted on a regional scale to provide basic data for selecting indicator species of Gotjawal and evergreen broad-leaved forests on Jejudo Island.

Recently, it has become known that Gotjawal terrain is an important area, therefore the study on this area has conducted in the geological, ecological, and cultural aspects. The studies on bryophytes of Gotjawal, however, have not been sufficiently performed. This study presents a survey on the bryophytes of the evergreen broad-leaved forest of Cheongsu-ri at Hangyeong Gotjawal in the southwestern part of Jejudo Island, Korea. A total of 72 taxa belonging to the Bryophyta (18 families 43 genera 55 species) and Marchantiophyta (11 families 13 genera 17 species) were determined and the liverwort index was 23.6%. Predominant life-form was weft. The rates of the bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that the forests are widespread and dense in this study area. Upon an investigation of the substrates, the bryophytes on rocks were most diverse. The results appear to stem from the fact that volcanic rock masses of various sizes lay scattered over the study area, offering numerous micro-habitats for bryophyte due to one of the characteristics of Gotjawal. We suggest that more detailed studies should be conducted at the regional scale to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests on Jejudo Island.

본 연구는 제주도 한라산 북동사면의 선흘 곶자왈에 위치하고 있는 동백동산의 선태식물을 대상으로 하였다. 식물상 조사 결과, 선류는 22 과 44 속 62 종, 태류는 12 과 16 속 23 종으로 총 85 종이 확인되었다. 이 중 Diphyscium perminutum Takaki, Racomitrium japonicum Dozy & Molk., 그리고 Isopterygium minutirameum (M$\ddot{u}$. Hal.) A. Jaeger.는 한국미기록식물에 해당하여 본 연구를 통해 기재하였다. 태류지수는 27.0%이고, 직물형의 생활형에 해당하는 선태식물이 가장 많이 분포하는 것으로 나타났다. 또한 중습성 또는 습성의 환경에 주로 생육하는 선태식물의 비율이 건조한 환경에서 주로 출현하는 선태식물의 비율보다 높았다. 본 연구를 통해 조사지 내의 상록활엽수림, 습지, 나지 등에 의한 다양한 환경 요인이 종의 조성과 분포에 영향을 미치고 있는 것으로 파악되었다. 그리고 이 지역에서 암석은 선태식물에 미소환경을 제공하는 데 있어 주요한 요인으로 작용하는 기질이었다. 특히, 동백동산의 소택지에 분포하는 선태식물은 면적에 비해 독특하고 다양하며, 관속식물과 함께 모자이크 공간 유형의 식물군락을 이루는 것으로 나타났다. 아울러 제주고사리삼과 자생지의 보존과 복원을 위한 기초 자료를 제공할 수 있도록 한국 고유 양치식물인 제주고사리삼이 자생하는 소택지를 대상으로 한 보다 정밀하고 종합적인 조사를 제안하는 바이다.
