Discussion

Chenopodium foliosum is probably native to the mountains of south and central Europe and western Asia. Several closely related segregate species are currently recognized within the C. foliosum group (P. Uotila 1979, 1993, 1997).

Chenopodium foliosum listed and illustrated in J. C. Hickman (1993) is in fact C. capitatum var. parvicapitatum.
