Eight species of Chondria from Korea are described. C. expansa Okamura occurs on the bed of Corallina pilulifera community in the intertidal zone of Cheju Island. The erect axes of the plants of C. expansa are terete or compressed. The plants of terete one are more frequently found in Cheju Island. C. intertexta Silva was previously known as C. intricata Okamura in Korea. The pericentral cells of the plants of C. intertexta include a radial spine-from structure. C. arcuata Hollinberg, C. lanceolata Harvey and C. lancifolia Okamura are added to Korea flora. C. crassicaulis Harvey is doubtful of the affinity with the genus Chondria. The plants of C. pellucida sp. nov. was known previously as C. dasyphylla (Woodward) C. Agardh in Korea. However, the plants at hand are quite different in morphology from the type collections of the latter species. C. chejuensis sp. nov. occurs on bed-rock slightly covered with sand in the lower tidal zone of Hengwon, Cheju Island. C. atropurpurea Harvey and C. stolonifera Okamura of which were previously reported in Korea are excluded in this study because of scanty material.
