'Selected, among the several species common to both Linng and Tournefort, 

 which answer Linne's generic characterization in Genera Plantarum, ed. V. 10. 1754, 

 and are native to Linne's country Sweden, because of its officinal nature. This 

 species had a long historic right to the name "Veronica."
