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.
