ABSTRACT. An annotated list of liverworts collected in the forest belt and in the floodplain of the Timpton River in the Aldan Upland includes 80 species. The data on structures associated with reproduction, localities, substrates, habitats, and growth pattern are provided and associated species are listed. Most liverwort species in the study area grow on rocky substrates and decaying wood. Two mainly southern species are new for Yakutia: Harpanthus scutatus and Targionia hypophylla. Diplophyllum obtusatum, Frullania davurica, F. koponenii, Porella platyphylla and Scapania apiculata also occur here on their northern limit of distribution in Siberia.
