|discussion=<p>Most reports of <i>Veronica biloba</i> pertain to <i>V. argute-serrata</i>. There are gatherings from potentially mixed populations (for example, Mt. Baldy, British Columbia, Lomer 97-118, UBC). Studies on phenotypic plasticity in these two species are necessary to ascertain the diagnostic characters.</p><!--
--><p><i>Veronica</i> intercedens Bornmüller, native to western Asia, was recently reported from Idaho. It is most similar to <i>V. biloba</i>, distinguished by a large calyx with broadly ovate lobes (3–5 mm versus 2–3.5 mm), the pairs joined by more than one half.</p>
