Veronica agrestis
Veronica dillenii
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 dillenii is closely related to V. verna but with larger flowers; it may have been overlooked and may be distributed more widely. Most herbarium specimens of V. dillenii blacken when dry due to the presence of aucubin, which distinguishes them from V. verna.
