Discussion

Stem indument of Veronica peregrina has been used to distinguish var. xalapensis with a glandular-hairy stem (F. W. Pennell 1935), a variety that seems to be confined to drier places than the type variety. Variety laurentiana is also differentiated from var. peregrina in having a glandular-hairy stem, fleshier leaves, shorter stamens, smaller corollas, and slightly differently shaped capsules (Frère Marie-Victorin and J. Rousseau 1940).

Veronica ×tournefortii Villars [V. officinalis var. tournefortii (Villars) Dumortier] refers to the hybrid between V. officinalis and V. allionii Villars in Europe and is not applicable to any North American plant.

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

Although difficult to separate, Veronica beccabunga and V. americana are maintained as species here. Evidence suggesting separate species status is different ploidy level (the tetraploid level is rare in V. beccabunga) and the occurrence of V. americana in more natural habitats.
