Discussion

Veronica agrestis is similar to the more frequent V. persica and probably frequently overlooked and to be expected elsewhere. However, it should be noted that it is less common than V. persica or V. polita and always in more humid habitats.

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.
