1589 Lamium album L.

This species is now widely distributed. Its geographical origin seems to be uncertain. However, it is reasonable to assume that this weed originates from E. European and W. Asiatic mountains. It has also been introduced into N. America. The E. Asiatic population is distinguished as subsp. barbatum (Sieb. & Zucc.), syn.: L. petiolatum auct. japon. Cf. also Meusel et al. 1978, map p. 376.
