Veronica agrestis
Veronica argute-serrata
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 argute-serrata has been recorded mostly under the name V. biloba and occasionally under V. campylopoda Boissier. Most of the records for V. biloba likely belong under this name. Veronica biloba is also found in the flora area, sometimes mixed with V. argute-serrata; V. campylopoda has not been recorded from the flora area. A chromosome count of 2n = 18 (C. R. Bell 1965) for American material is suspicious because 2n = 42 has been reported multiple times in Turkish plants, and a base chromosome number of × = 9 is not known in related species.
