681 Chenopodium hybridum L.
This widespread species s. str. (subsp. hybridum) is confined to Eurasia, where it is widely spread by man, for instance in Scandinavia. It is considered not to be introduced in N. America. Subsp. gigantospermum (Aellen) Hult. occurs there instead. The species s. lat. belongs to the circumpolar plants (Hultén, Circumpol. II, p. 142 and map 134). Cf. also Meusel et al. 1965, map p. 132.
