Discussion | Alpine plants of Veronica serpyllifolia with bright blue, larger corollas, and smaller, hairier raceme axes have been treated at various ranks under the epithet humifusa. The characters are labile and show intergradations with the typical plants. Veronica serpyllifolia is widespread; it is not clear where it is native.

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.
