Lower Trenta valley, between villages Soča and Trenta, left bank of river Soča, about 400 m downstream of Matevž's farmhouse, Trenta 1, East Julian Alps (Posočje, Slovenia)family
Radulaceae
notes Syn.: Jungermannia complanata L., Radula hallii Austin - Habitat: river shore, light riparian forest, Salix eleagnos dominant tree; almost flat terrain; calcareous, colluvial ground; exposed to direct precipitations, humid and partly sunny place; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevations 530 m (1.740 feet), alpine phytogeographical region (M. Wraber, 1969). - Substratum: on bark of fallen, not yet rotten branch of Fagus sylvatica. - Comment (pertains to pictures in the Flicker album Radula complanata): Radula complanata is widespread in Europe (with an exception of far-north countries), north Africa, Asia and North America and very common liverwort in Trenta valley and elsewhere. It can be found most commonly on the trunks, branches and roots of broadleaved trees and bushes but also on rocks and other hosts in woods, thickets and hedges. From far it often looks like large green patches on tree bark. Perianths are common (see Fig. 5a), so are gemma too (see Fig. 5b, lobes' edge). It is a species which was once considered rare and in some countries red-listed. However, lately it shows a massive expansion, already in 20th and particularly 21st century, presumably because of recent reduction of air pollutants. The plant is very old. Based on molecular analysis of fossil material we know that it split from common ancestor almost 200 million years ago. - Ref.: (1) Personal communication (conf.) with Doc.
