Abstract
A synopsis of Boraginaceae subfam. Hydrophylloideae and Heliotropioideae in Italy is given, as the first contribution to the treatment of the family for the project Flora Critica d'Italia. The work is mainly based on the critical study of herbarium material conserved in most of the Italian collections. All the relevant floristic reports were examined and all the specific names of taxa reported from the National territory were typified, as well as a number of infraspecific ones. Seven species are recognized, only three of which in genus Heliotropium are autochtonous, with one represented by an endemic subspecies. A complete floristic treatment is provided, including analytical keys, distribution maps and lists of selected “specimina visa”, as well as original iconographies to help with species identification.
