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 cusickii is sister to V. copelandii and closely related to V. wormskjoldii subsp. nutans (D. C. Albach et al. 2006).
