Taxonomy of Veronica L. subsect. Veronica (Plantaginaceae) in the western Mediterranean

Abstract

Veronica subsect. Veronica in the western Mediterranean area is revised taxonomically in light of new karyological, palynological, and further diagnostic morphological features. The data confirm that the subsection comprises only two species and a hybrid taxon. Many previously recognized species are reduced to synonyms. An updated taxonomic treatment is supplied, including detailed descriptions of the taxa involved, as well as a list of synonyms, types of name, selected representative specimens, and a distribution map.
