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 cusickii is sister to V. copelandii and closely related to V. wormskjoldii subsp. nutans (D. C. Albach et al. 2006). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
