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 sublobata is closely related to V. hederifolia and has been frequently synonymized with or treated as a subspecies of the latter. It has rarely been reported in the flora area and is surely more widespread than indicated above. It seems to be more rare than V. hederifolia with only about a dozen verified records from seven states. However, its frequent occurrence in cultivated habitats in Europe makes it likely that it has been introduced to the flora area on multiple occasions.
