Remarks — A short-lived perennial with a tap root, Amaranthus deflexus is native to temperate South America ( Argentina, Bolivia, Chile, Peru, Uruguay); it is introduced as a ruderal weed in North America, Europe, SW Asia, N and S Africa, Korea, Japan, Tasmania and New Zealand ( Pedersen 1999: 23; Bayón 2015: 324; POWO 2022). Established in the Mediterranean area since the early 19 th century, it was first mentioned from Greece (North East, Kavala) under its synonym A. prostratus (Grisebach 1846) ; it now occurs countrywide ( Strid & Tan 1997: map 270) and is considered fully naturalized ( Arianoutsou & al. 2010). The same is true for adjacent countries N of Greece ( Iamonico 2015a).
