Abstract

This work increases and updates the knowledge of the distribution of seven species of rare and/or threatened ferns (Cystopteris diaphana (Bory) Blasdell, Cystopteris fragilis (L.) Bernh., Dryopteris carthusiana (Vill.) H.P.Fuchs, Leptogramma pozoi (Lag.) Heywood and Dryopteris guanchica Gibby & Jermy in Galicia with the contribution of 19 new records. The localities where sampling was carried out are concentrated in the province of A Coruña, in the municipalities of Arteixo, Carral, Cambre, Cerceda, Oleiros, Ordes and Sada, and the provinces of Lugo (Sober) and Pontevedra (Pontevedra). In addition to the location data, we provide information on their ecology, habitat, conservation status, demography, taxonomy, and personal observations of the species mentioned together with information on the accompanying communities.
