Studies about genus Romulea underlined how this is a critical group of the Italian flora. This genus is characterized by an high level of polymorphism caused mainly by hybridization, polyploidy and peculiar climatic/edaphic conditions. In Italy are currently recognized to be 12 taxa, while 16 in the main west Mediterranean insular systems. Among them, Sardinia has the higher richness with 10 entities, followed by Corsica (8), Sicily (6), Tuscan Archipelago (5), Maltese Archipelago (5) and Balearic islands (3). Nowadays analyses about pollen, stigmas and stomata morphology, karyology and molecular biology are still in progress, in order to product a phylogentic study of this genus in Italy and to attempt solving some taxonomical doubts.
