Chorology:― Amaranthus graecizans s.l. is native to Europe, Central and Western Asia, and Northern Africa and considered as introduced in some European countries, North America, South Africa, and Australia ( Iamonico 2015a). It is native in Saudi Arabia ( Hassan et al. 2022).

At subspecific rank two main distribution areas can be highlighted, one ranging from Central to southern Europe plus North Africa [ subsp. graecizans and subsp. sylvestris (Vill.) Brenan ], the second one in eastern Europe ( Russia and adjacent territories) plus Central and southern Asia [ subsp. aschersonianus (Thell.) Costea and subsp. thellungianus (Nevski) Gusev ] (see Iamonico 2015a: 34).
