ABSTRACT. A list of 172 species of mosses and 57 species of liverworts collected by the first author in 2002 in two localities in SW Kamchatka is provided. These localities are: the Middle Bannaya River – 52°54’N 157°30’E  (#1 in Fig. 1) and the interfluve of Bolshaya Bystraya and Nachilova Rivers – 53°06’N 156°53’E– (#2 in Fig. 1). The list is annotated by data on frequency, distribution, ecology, reproduction, and, in some cases, on taxonomy and on sporophytes occurrence. 17 species of mosses and 15 species of liverworts are new for Kamchatka. Jungermannia evansii is recorded for first time for Eurasia. New combination is proposed: Schistochilopsis obtusa (Lindb.) Potemkin comb. nov. A taxonomic and geographic consideration of the species list is provided.
