An updated geographical distribution of the genus Gagea Salisb. in Sardinia with a grid map for each taxon is given. This study is based on literature, herbarium and field investigations. The examined species are G. bohemica (Zauschn.) Schult. & Schult. f., G. dubia A. Terracc., G. foliosa (C. Presl) Schult. & Schult. f., G. fragifera (Vill.) E. Bayer & G. López González, G. granatellii (Parl.) Parl., G. lojaconoi Peruzzi and G. soleirolii F. W. Schultz. The occurrence in Sardinia of the phytogeographically interesting G. fragifera is here confirmed in a single locality. Single new localities are reported for G. dubia and G. granatellii. Finally, an analytical key for the identification of the studied species is presented.
