Discussion | The names Veronica buxbaumii Tenore and V. tournefortii C. C. Gmelin (not V. ×tournefortii Villars) have been used for V. persica. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Plants of Veronica polita are similar to those of the more frequent V. persica and are probably frequently overlooked. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
