Discussion | Veronica catenata seems to be a relative of V. anagallis-aquatica that is more cold-adapted, as seen in Europe (R. Götte 2007), and native to the flora area. Although no specimens were seen it may be found in Alaska, Connecticut, and Kentucky. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
