Abstract

All known Italian Gagea species (23) representing seven out of 14 sections were included in this study. Morphological, molecular and combined data support the basal position of G. trinervia (Anthericoides). According to the molecular data, the sections Anthericoides, Lloydia, Gagea, Minimae and Spathaceae are very well supported; representatives of the sections Didymobulbos and Fistulosae clustered together in the same clade. In this clade, several near-related species groups (series) were recognised. According to 35 morpho-anatomical, ontogenetic and karyological data the section Gagea forms a well-defined monophyletic clade. Within this clade G. tisoniana, G. pusilla and G. cfr. paczoskii are near related. The position of the critical putative hybrid taxa G. luberonensis and G. polidorii is discussed. New series Solenarium (Dulac) Peruzzi and Tison, Occidentales (A. Terracc.) Peruzzi and Tison and Saxatiles (A. Terracc.) Peruzzi and Tison are proposed.
