Note. Echium italicum subsp. siculum (Lacaita) Greuter & Burdet is an accepted taxon according to Greuter et al. (1984) and Conti et al. (2005), but not in Pignatti (1982) who included it in the circumscription of the typical species. More studies are needed to ascertain the taxonomic value of the diagnostic characters of this mostly southern Italian race (inflorescence more widely branched, denser indumentum), which is often connected to the typical E. italicum by intermediate morphotypes.
