Synopsis of Boraginaceae subfam. Boraginoideae tribe Boragineae in Italy

A synopsis of the Italian taxa of tribe Boragineae (Boraginaceae, subfam. Boraginoideae) is given as a second contribution to the treatment of the family for the Flora Critica d’Italia project. The work is mainly based on the critical study of herbarium material and extensive literature survey. All relevant floristic reports were examined and types of all the accepted (51) and most (37/46) of the synonymized names of taxa, specific and infraspecific, reported from the National territory are indicated. In the light of karyological and morphological evidence, the new combination Pulmonaria vallarsae subsp. apennina is proposed. As a result, 12 genera and 37 species are recognized, of which 7 are allochtonous and 6, plus two subspecies, are endemic. A synthetic floristic treatment is provided, including analytical keys, hybrids, list of synonyms and short distribution notes. In addition, detailed distribution maps are provided, together with the lists of the selected specimens upon which they are based
