Publication: Sp. Pl. 2: 1061. 1753.

Origin: Native

selected vouchers: WTU

Notes: FNA2: "Among the many infraspecific taxa that have been named in this species, Equisetum arvense var. boreale Bongard has been most generally accepted and has been applied to plants with tall, erect stems with 3-ridged branches. Because both 3-ridged and 4-ridged branches may occur on a single stem, the variety boreale is not recognized here as distinct (R.L. Hauke 1966)."
