Publication: Mem. New York Bot. Gard. 1: 131. 1900.
selected vouchers: WTU
Notes: Similar to C. pratericola. In H&C the range of Chenopodium atrovirens (under the name C. fremontii var. atrovirens (Rydb.) Fosberg) appears to include Washington, according to KZ. But FNA could find no WA vouchers. Thus we assume that those reports are based on what H&C called C. fremontii var. fremontii, which is documented from Grant Co., WA.
