Discussion | 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.) |
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.) |
