Included in C. album in Michigan Flora.
Presumably native, but occurring in similar sorts of disturbed, open areas as many other Chenopodium species.
This is like Chenopodium album, but quite distinct in its pitted seed pattern. Our plants fall into two varieties, var. zschackei (Murr) Graebn. with seeds 1.2–1.5 mm in diameter, known from Livingston Co. (with an immature 1901 collection from Isle Royale annotated as “probably” this by H. A. Wahl, but not mapped) and the apparently more common var. bushianum (Aellen) Cronquist with mature seeds 1.7–2 mm in diameter. Both are likely much overlooked.
