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.
