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.) |
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.) |
