While preparing a floristic study of Korean hepatics, we discovered the following 10 unrecorded species from Mt. Jiri-san (maximum height, 1,915 m) and Mt. Seorak-san (maximum height, 1,708 m): Neotrichocolea bissetii (Mitt.) S. Hatt., Calypogeia angusta Steph., Cephaloziella massalongii K. Mller, Harpanthus scutatus (F. Weber & D. Mohr) Spruce, Plectocolea torticalyx (Steph.) S. Hatt., Anastrophyllum michauxii (F. Weber) H. Buch, Lophozia excisa (Dicks.) Dumort., Lophozia lantratoviae Bakalin, Mylia verrucosa Lindb., Scapania sphaerifera H. Buch. They are distributed near streams and/or on the top of a ridge on Mt. Jiri-san and Mt. Seorak-san.

A total of ten unrecorded liverwort species in the Hepaticae flora of Korea were collected on Mt. Deogyu (1,614 m). The ten species are Tetralophozia filiformis (Steph.) Urmi., Herbertus buchii $Jusl{\acute{e}n$, Bazzania japonica (Sande Lac.) Lindb., Cephaloziella hampeana (Nees) Schiffner ex Loeske., Jungermannia japonica Amak., Marsupella alpina (Gott. ex Husn.) Bernet., Pedinophyllum interruptum (Nees) Kaal., Frullania polyptera Tayl., Jubula hutchinsiae ssp. javanica (Steph.) Verd., and Marchantia polymorpha ssp. montivagans Bischl. and Boisselier-Dubayle. They are distributed near streams and/or at the top of a ridge on Mt. Deogyu.

While preparing a floristic study of Korean hepatics, we discovered the six unrecorded species of Lejeuneaceae from Mt. Seolak, Mt. Gaya, Geojedo, Wando and Gageodo. Archilejeunea kiushiana, Drepanolejeunea angustifolia, Lejeunea aquatica, Lejeunea otiana, Leucolejeunea japonica, and Spruceanthus semirepandus, are reported here. A. kiushiana was characterized by unlobed underleaves, homogeneous oil-bodies, and four to six perianth-keels. D. angustifolia is similar to D. ternatensis, but it differs in the dorsal margin of the leaf-lobe, which is entire or denticulate, spines never present, and leaf cells smooth or with minute dorsal bulging. L. aquatica is similar to L. japonica in that it has a wider and similar shape (wider than long) of its underleaves and has homogeneous oil-bodies. The former, however, has minute leaf-lobules (5-15 cells), 1/10 to 1/5 the length of the leaf-lobe, versus leaf-lobules 1/4 to 1/3 the length of the leaf-lobe. L. otiana is similar to L. kodamae in that it has a large and acute first tooth of the leaf-lobule but differs in having plain leaf-lobules obliquely quadrate and an indistinct second tooth. Drepanolejeunea (Spruce) Schiffn. is widely distributed in tropical and subtropical regions (Mizutani, 1961). L. japonica is characterized by entire underleaves; one large, coarsely segmented oil-body per leaf cell; and a large second tooth of the leaf lobule, two to six cells long, and two to three cells wide at the base. S. semirepandus is widely distributed in tropical and subtropical regions in Asia. This species is characterized by small homogeneous and numerous oil-bodies, up to 10 smooth perianthkeels, and leaf-lobe acute at the apex.

This study presents a survey on the bryophytes in Dongbaek-dongsan located at Seonheul Gotjawal on the north-eastern face of Mt. Halla in Jeju Island, Korea. A total of 85 taxa belonging to the Bryophyta (22 families 44 genera 62 species), Marchantiophyta (12 families 16 genera 23 species) were found. Among them, 3 moss species, Diphyscium perminutum Takaki, Racomitrium japonicum Dozy & Molk., and Isopterygium minutirameum (M$\ddot{u}$. Hal.) A. Jaeger. were new additions to the bryophyte flora of Korea. The liverwort index was 27.0%. Predominant life-form was weft. The rates for the bryophytes dominating in mesic to hygric sites were higher than for the bryophytes mainly observed in xeric habitats. We considered that the composition and distribution of species are affected by the different environmental factors according to the evergreen broad-leaved forests, wetlands and exposed spaces. Moreover, the rocks were the substrate type that play a major role in providing the micro-habitats for bryophytes in this area. Particularly, the bryophytes of swamps in this area were very unique and various for its limited space and showed plant communities with mosaic spatial pattern, along with vascular plants. We suggest more detailed and comprehensive studies on the swamps where endemic fern Mankyua chejuense B. -Y. Sun, M. H. Kim & C. H. Kim inhabits to provide valuable information for the conservation and restoration of the species and habitats.

This study introduces the bryological history and literature of the Korean Peninsula. The French missionary Urban Faurie was the first person to collect Korean bryophytes at the beginning of the 20th century. Most of his bryophyte collections from Korea were studied and recorded by Jules Cardot (for mosses) and by Franz Stephani (for liverworts). Japanese studies of Korean bryophytes were described in chronological order. Hong Won Shic and Choe Du Mun carried out an inventory and flora research on bryophytes in South Korea. The most recent bryological studies of North Korea are also reviewed here as a reference.

1. This study was made on the flora of Hepaticae in the crater of Mt. Hanla ($33^{\circ}$20' N. Lat. $126^{\circ}$4' E. Long), Isl. Quelpart. 2. the total fo the occurring species of the crater are twelve, out of which the following 6 species are new to the Korean flora. (1) Bazzania tricrenata (Wahlenb.) Trev. (2) Plagiochila satoi Hatt. (3) Scapania ampliata St. (4) Radula boryana (Web.) Nees. (5) Cololejeunea kodamae Kamimura. (6) C. macounii (Spruce) Evans. 3. The hepaticae flora of the crater consists of the following elements: Holarctic element. 4 species (33%), East Asiatic element. 2. species (16%), Korean-Japan element. 5. species (41%), North-Pacific element. 1 species (8%).
