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.

Veronica catenata seems to be a relative of V. anagallis-aquatica that is more cold-adapted, as seen in Europe (R. Götte 2007), and native to the flora area. Although no specimens were seen it may be found in Alaska, Connecticut, and Kentucky.
