1640 Veronica serpyllifolia L. subsp. serpyllifolia

This subspecies (cf. no. 1641 subsp. humifusa [Dicks.] Syme) originates from the temperate part of Eurasia. It has spread as a weed northwards in Europe and, for instance, to N. and S. America, E. Asia, Australia and New Zealand. The present distribution is discontinuous circumpolar (Hultén, Circumpol. Il, p. 260 and map 251). Cf. also Meusel et al. 1978, map p. 396.
