Abstract

Specimens of the rare species Cynodontium suecicum (Rhabdoweisiaceae, Bryophyta) were collected near Drozdovka Bay on the Barents Sea coast of the Kola Peninsula (Russia) in 2016. They were compared with samples of C. suecicum from the Teriberka area (also the coast of the Barents Sea) gathered in 1977 by R. N. Schljakov. The morphological features of both groups of samples were studied, and nucleotide sequence data for ITS1-2 nrDNA and trnL-F cpDNA were obtained. Molecular analysis suggested C. suecicum as a hybrid that inherited cytoplasmic DNA from C. tenellum and nuclear DNA from Kiaeria blyttii. Taking into account the rather clear morphological delimitation against other species, combined with the stability of genetic characters, we believe that S. suecicum should be retained as a species-level taxon.
