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.) |
Veronica dillenii is closely related to V. verna but with larger flowers; it may have been overlooked and may be distributed more widely. Most herbarium specimens of V. dillenii blacken when dry due to the presence of aucubin, which distinguishes them from V. verna.
