The name Chenopodium atripliciforme Murr (sometimes incorrectly cited as “atriplicifolium”) has often been treated as a synonym of C. bryoniifolium, or misidentified as C. opulifolium Schrader ex Candolle. However, C. atripliciforme is a separate species reported from NE Afghanistan, N India, and N Pakistan. Judging from several herbarium specimens available, it probably also occurs in the mountains of SC Asia. It may also be expected to occur in W China.
