Gagea tisoniana Peruzzi et al. sp. nov. is described and its taxonomic relationship is discussed. The new species, which appears endemic to C Italy, is close to G. pratensis (Pers.) Dumort., G. pusilla (F. W. Schmidt) Sweet and to other mainly poorly known (i.e. G. succedanea Griseb. et Schenk, G. transversalis Stev., G. paczoskii (Zapal.) Grossh.) or as yet undescribed taxa from E Europe and E Mediterranean area. The recognition of the new taxon G. tisoniana is claimed on the basis of anatomical, karyological, ecological and phytogeographical data. Maps of the Italian distribution of G. pratensis (2n = 60), G. pusilla (2n = 24) and G. tisoniana (2n = 24) are presented, together with an analytical identification key. Finally, G. pratensis is here recorded for the first time in Tuscany (Monte Cetona).
