Contributions to the taxonomy of some genera and species of the Sardinian flora are presented. In particular, one species (Narcissus supramontanus) and a sub-species (N. supramontanus subsp. cunicularius) are described as new for the Island. The status of two subspecies of S. insularis Sommier within the genus Sesleria has been changed. Other contributions concern typification of Delphinium gracile Moris, D. cyatophorus Moris and Verbascum plantagineum Moris and the report of the occurrence of Bifora radians Bieb. and Bromus macrantherus Hackel ex Enriques in Sardinia. Revision of the relevant material has allowed better definition of the occurrence on the Island of some taxa belonging to the genera Delphinium, Aphanes and Sanguisorba.
