Chenopodiastrum simplex (Torrey) S. Fuentes, Uotila & Borsch[HC2]

giant goosefoot, maple leaf goosefoot

Publication: Willdenowia 42(1): 14. 2012.

Origin: Native

selected vouchers: WTU

Notes: A forest species that can occur in waste ground. Here we follow the taxonomy of FNA, and consider Chenopodium hybridum L. to be an Old World species not recorded in our area, with differences in the seed coat, pericarp, and chromosome number (Baranov 1964).

FNA4: "A closely related Eurasian diploid species, Chenopodium hybridum Linnaeus, probably also occurs in North America as introduced. Its occurrence in the New World needs confirmation. Chenopodium simplex differs from its Eurasian counterpart in having a smoother seed coat, a yellowish pericarp that is more adherent to the seed, and a different chromosome number (A. I. Baranov 1964; R. D. Dorn 1988b)."
