± 75 genera, 900 species: cosmopolitan, especially disturbed, arid, saline or alkaline soils; some cultivated for food, ornamental; many naturalized, ruderal or agricultural weeds. [Müller & Borsch 2005 Ann Missouri Bot Gard 92:66–102] Amaranthaceae including Chenopodiaceae by some. Polycnemoideae, represented in CA by Nitrophila, formerly considered subfamily of Chenopodiaceae, but needs further research. Guilleminea densa (Willd.) Moq. var. aggregata Uline & W.L. Bray is a waif. Froelichia gracilis (Hook.) Moq. is an historical waif. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.
