Atriplex centralasiatica is closely related to A. sibirica. Grubov (Rast. Tsentral. Azii 2: 33. 1966) proposed varietal rank for the former under the latter; however, Sukhorukov (Taxon. Chorol. Sp. Gen. Atriplex Russia Adjac. Countries, 2003) confirmed the specific status of A. centralasiatica.

+ Fruiting bracts mostly 3-lobed, 1-4(-4.5) cm, middle lobe larger than lateral ones, margins broader, triangular-denticulate, pedicel usually 1-3(-5) cm.   13b var. megalotheca
