New records of the rare liverwort Mannia triandra (Scop.) Grolle in Croatia

Mannia triandra (Scop.) Grolle is a rare thalloid liverwort species, known from a few, mostly sporadic, historical records in Croatia. In the recent years, two findings have been recorded on Mt Žumberačka Gora and one from Plitvice Lakes, and subsequently published. During 2022, two adjacent populations close to these previously known localities were found, but also a first locality in Gorski Kotar region (in the canyon of the River Kamačnik) was recorded. In addition, an old literature record from the area of Dubrovnik city from the beginning of the 20th century was found while browsing literature for this paper. Thanks to these new findings, we are now closer to a better understanding of the species ecology and habitat preferences in Croatia.
Mannia triandra (Scop.) Grolle je rijetka talozna jetrenjarka. U Hrvatskoj je donedavno bila poznata samo iz povijesnih sporadičnih nalaza. U proteklih nekoliko godina objavljena su dva nalaza sa Žumberačke gore i jedan s Plitvičkih jezera. Tijekom 2022., zabilježene su dvije populacije blizu tih ranije poznatih nalazišta, ali i prvi nalaz u Gorskom kotaru, u kanjonu rijeke Kamačnik. Tijekom pisanja ovog priloga pronađen je i stari literaturni nalaz ove vrste s početka 20. stoljeća iz okolice grada Dubrovnika. Zahvaljujući recentnim nalazima, na korak smo boljem razumijevanju ekologije i potencijalnim staništima ove vrste u Hrvatskoj.
