|discussion=<p><i>Veronica anagallis-aquatica</i> is widespread. It is not clear whether it is native to the flora area; it is certainly introduced in some states and commonly dispersed by human activity. The species varies with water availability. It is frequently confused with <i>V. catenata</i>. Ecological differences (see discussion under 15. <i>V. catenata</i>) may suggest that <i>V. anagallis-aquatica</i> does not occur in most parts of Canada and Alaska from which the species is reported but is present in some states excluded from the distribution area due to the lack of herbarium specimens seen (for example, Alabama, Arkansas, Idaho, Louisiana, Maryland, Massachusetts, Mississippi, South Carolina, and Vermont). Hybrids are frequent in Europe (V. ×lackschewitzkii J. Keller) and have been reported for California and Nebraska (L. R. Heckard and P. Rubtzoff 1977). The sterile hybrids never form capsules and bear relatively long inflorescences. Another closely related species, V. anagalloides Gussone (= V. salina Schur), is not present in North America.</p>
