|discussion=<p>Among the many infraspecific taxa that have been named in this species, <i>Equisetum arvense</i> <i></i>var.<i> boreale</i> 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).</p>
