Discussion | 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.) |
Alpine dwarf forms of Veronica scutellata tend to have relatively broad leaves and may therefore be easily confused with other species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
