Abstract
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.
