Discussion | Subspecies 3 (1 in the flora). Subspecies abscondita M. A. Fischer is found from eastern Turkey to western Iran, while the native range of subsp. muscosa (Korshinsky) Elenevsky extends from eastern Iran to southern China.

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.
