title: Recently resurrected for European liverwort flora – Frullania calcarifera Steph., new addition for the Crimean Peninsula
abstract: Frullania calcarifera is a long forgotten taxon, which originally has been described by F. Stephani in 1887 from Portugal, but largely overlooked since that time due to its synonymization with F. tamarisci s.str. Based on both molecular and morphological data, F. calcarifera is here for the first time recorded for the Crimean liverwort flora. A morphological description and figures are provided and differentiation, ecology and distribution are discussed.
