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.) |
Veronica triloba is known in the flora area from three recent collections in California and Ohio; it is possibly more widespread than reported here. It is closely related to V. hederifolia. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
