ABSTRACT. Two species of the genus Frullania are revealed in the Late Eocene amber from Rovno (Ukraine). One is referred to F. varians, a widespread species in Baltic amber, whereas the second species with entire underleaves, similar to those in extant F. davurica and F. jackii, is described as a new species, F. ucrainica Konstant. & Ignatov. The latter is known by one short shoot fragment with perianth. A number of specimens are illustrated and briefly described as Frullania sp., as the deficit of characters does not allow precise identification.
