Discussion | Specimens of Veronica verna from Alberta have not been verified. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Veronica agrestis is similar to the more frequent V. persica and probably frequently overlooked and to be expected elsewhere. However, it should be noted that it is less common than V. persica or V. polita and always in more humid habitats. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
