Liverworts from Rovno Amber (Ukraine). 8. Frullania ekaterinae sp. nov. and F. schmalhausenii sp. nov

A study of Rovno amber revealed two liverworts of the genus Frullania (Frullaniaceae, Marchantiophyta), new to the Late Eocene flora of Rovno amber. One of these liverworts is characterized by the mammillose surface of the upper part of ventral lobules. This taxon is described as F. ekaterinae Mamon...

Zusammenfassung:A study of Rovno amber revealed two liverworts of the genus Frullania (Frullaniaceae, Marchantiophyta), new to the Late Eocene flora of Rovno amber. One of these liverworts is characterized by the mammillose surface of the upper part of ventral lobules. This taxon is described as F. ekaterinae Mamontov, Ignatov, and Perkovsky, sp. nov. The other is distinguished by the ventral lobules remote from the stem and tilted outwards. This taxon is interpreted as a new species, F. schmalhausenii Mamontov, Ignatov and Perkovsky, sp. nov.
