“…Finally, the ecology of J. polessica is similar to both that of N. herzogii [a strictly corticolous species (Kamimura 1961;Mizutani 1961;Bakalin 2019)] and the East Asian J. kwangsiensis [also strictly corticolous (Chang & Gao 1984)]. Interestingly, J. polessica is found together with a Nipponolejeunea species in a syninclusion within the same amber piece (SIZK-Be-18).…”

“…The study of liverworts from Rovno amber began with the description of several species of the genus Frullania Raddi (Konstantinova et al 2012). In subsequent studies (Mamontov et al 2013;2015a, b, c;2019;2024a, b), seven more species of Frullania were discovered, as well as eight species within the genera Acrolejeunea (Spruce) Schiffn., Anastrophyllum (Spruce) Steph., Cephaloziella (Spruce) Schiffn., Leptoscyphus Mitt., Nipponolejeunea S.Hatt.

A new fossil leafy liverwort species is described based on its inclusion in Eocene Rovno amber. This species has morphology that is characteristic of extant representatives of the families Frullaniaceae and Jubulaceae, i.e., conduplicate-trilobed leaves with a ventral lobule forming a saccate-clavate watersac with its mouth directed towards the base of the stem, larger dorsal lobes and deeply bifid underleaves. The leaf lobes in the studied plant seem to be dentate near the apex, a character state together with the shape of the underleaves and the underleaf insertion, connects the new species with the Jubulaceae, particularly the extant genera Jubula and Neohattoria, rather than with the Frullaniaceae. The minute size of the fossilized plant, as well as the shape and size of the ventral lobules is reminiscent of Neohattoria, but the more distant lobule position and presence of terminal gynoecia with a single floral series of bracts having entire margins better fit species of Jubula. The fossil is therefore better placed in Jubula, as J. polessica sp. nov., based on its overall morphological similarity with extant members of that genus.

The long coexistence of various floral elements, landscape diversity, and island isolation led to the formation of the richest Eurasian hemiboreal liverwort flora in the southern Kurils. This land that covers less than 5000 square kilometres and houses 242 species and two varieties of liverworts and hornworts. The flora ‘core’ is represented by hemiboreal East Asian and boreal circumpolar taxa. Other elements that have noticeable input in the flora formation are cool-temperate East Asian hypoarctomontane circumpolar and arctomontane. The distribution of some species is restricted to the thermal pools near active or dormant volcanoes or volcanic ash deposits; such species generally provide specificity to the flora. Despite the territorial proximity, the climate of each considered island is characterized by features that, in the vast majority of cases, distinguish it from the climate of the neighbouring island. The last circumstance may inspire the difference in the liverwort taxonomic composition of each of the islands. The comparison of the taxonomic composition of district floras in the Amphi-Pacific hemiarctic, boreal, and cool-temperate Asia revealed four main focal centres: East Kamchatka Peninsula and Sakhalin Island, the southern Sikhote-Alin and the East Manchurian Mountains, the mountains of the southern part of the Korean Peninsula, and the South Kurils plus northern Hokkaido. The remaining floras involved in the comparison occupy an intermediate position between these four centres.
