ABSTRACT. Tortula edentula sp. n. is described as a new for science from the Kuril Islands, the Russian Far East. Gametophytically it is similar to T. aestiva Hedw., but differs in peristome absence, dark colour of capsules and larger spores. A newly described variety, Barbula indica (Hook.) Spreng. ex Steud. var. kurilensis var. nov. differs from the type variety by more narrow lanceolate leaves, crisped when dry. Description, illustrations and comparison with close species are given.
