Discussion

Specimens of Veronica verna from Alberta have not been verified.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Veronica teucrium has often been considered an infraspecific taxon of V. austriaca; many records of V. teucrium have been reported under the name V. austriaca. The occurrence of V. austriaca in the narrow sense in the flora area could be neither supported nor excluded; it differs from V. teucrium mainly in distal leaves of the vegetative shoot linear and entire.

Related species have been introduced for horticultural reasons but apparently have not escaped. Veronica satureiifolia Poiteau & Turpin was reported from Missouri by G. Yatskievych [1999–2013; as V. scheereri (J.-P. Brandt) Holub] outside cultivation based on a single specimen and was similarly found in MIN but likely not naturalized. The name V. latifolia Linnaeus, which has at times been used for V. teucrium, is now considered ambiguous and should not be used (R. K. Brummitt 2007). Reports of V. teucrium in Saskatchewan have not been verified.
