Distribution of the genus Gagea (Liliaceae) in Sicily

An updated geographical distribution of the genus Gagea in Sicily 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. chrysantha Schult. & Schult. f. sensu stricto, G. dubia A. Terracc., G. foliosa (C. Presl) Schult. & Schult. f., G. fragifera (Vill.) E. Bayer & G. L.pez Gonz.lez, G. granatelli (Parl.) Parl., G. lacaitae A. Terracc., G. lojaconoi Peruzzi, G. sicula Lojac., G. trinervia (Viv.) Greuter. The occurrence in Sicily of the phytogeographically interesting G. mauritanica Durieu is here confirmed in three localities. Besides, the actual presence in Sicily of historically occurring G. lutea (L.) Ker Gawl., G. pratensis (Pers.) Dumort. and G. villosa (M. Bieb.) Sweet is not confirmed. Finally, an analytical key for the identification of the studied species is presented.
