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.) |
In the flora area, Veronica undulata was introduced near ports (Mobile, Alabama, and Portland, Oregon) before 1900 via ship ballast from trade with Asia, did not spread much, and may not have persisted. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
