Discussion | Specimens of Veronica verna from Alberta have not been verified. (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.) |
