Bryophytic similarity of the Italian regions with a focus on the Ligurian region

The bryophyte flora of Liguria region is compared with data available for other Italian regions. Comparisons were made in terms of biogeographical coherence, floristic similarity, and the number of scientific studies for each region. The aim was to provide a provisional evaluation based on bibliographic data, but with useful insights for an objective assessment of the state of knowledge and for the continuation of the study of hornworts, liverworts, and mosses in the Liguria
