Hornwort flora of Croatia

Hornworts are quite inconspicuous ephemeral bryophytes mostly inhabiting transient but regularly recurrent habitats subjected to yearly disturbances, such as arable and stubble fields with loamy and clayey soils. Globally, they are the least diverse group among bryophytes regarding the species number. Similarly, only four genera with eight species are known from Europe, five of which were reported from Southeast Europe. Only Phaeceros laevis (L.) Prosk and Phymatoceros bulbiculosus (Brot.) Stotler, W. T. Doyle et Crand.-Stotl. are listed in the available literature for Croatia ; however, with no new records for over 85 years in the case of P. laevis, and 100 years in the case of P. bulbiculosus. Our study, carried out in April 2013 and August 2018 in Central Croatia and focusing on the habitats suitable for hornworts, identified three new species for Croatia, including two new genera – Notothylas and Anthoceros. Record of very rare Natura 2000 species Notothylas orbicularis (Schwein.) A. Gray is the first in Southeast Europe and the southernmost in Europe, with previously known localities from only four Central European countries. Furthermore, we recorded Anthoceros agrestis Paton and Phaeoceros carolinianus (Michx.) Prosk., which are either very rare or, more likely, overlooked and understudied in Southeast Europe. Additionally, available data on hornworts from the literature and herbaria were examined and countrywide overview of the whole group is provided. Finally, these findings increase the richness of Croatian bryophyte flora to 711 taxa - 544 mosses, 162 liverworts and five hornworts.
