Taxonomy

There are four subgenera: ''Buglossum'', ''Buglossoides'', ''Buglossellum'' and ''Anchusa''. The first two form one subclade, the other two each a separate subclade. The subclade of the subgenus ''Anchusa'' (containing ''Anchusa capensis'') is largely unresolved. If we consider ''Anchusa'' s.l., then it includes the subgenus ''Limbata'', which diverges markedly in its floral morphology. The subgenera ''Buglossum'', ''Buglossellum'' and ''Buglossoides'' clearly need new independent entities, while the subgenus ''Anchusa'' needs a narrower concept. This way taxonomy and phylogeny with respect to ''Anchusa'' can become completely analogous. The following genera are synonyms for ''Anchusa'': ''Buglossum'' Mill., ''Hormuzakia'' Gusul, ''Lycopsis'' L. and ''Phyllocara'' Gusul. The genus ''Anchusella'' Bigazzi et al. is sometimes included in ''Anchusa''.
