Aerial stems dimorphic; vegetative stems green, branched, 2–60(–100) cm; hollow center 1/3–2/3 stem diam. Sheaths squarish in face view, 2–5(–10) × 2–5(–9) mm; teeth dark, 4–14, narrow, 1–3.5 mm, often cohering in pairs. Branches in regular whorls, ascending, solid; ridges 3–4; valleys channeled; 1st internode of each branch longer than subtending stem sheath; sheath teeth attenuate. Fertile stems brown, lacking stomates, unbranched, shorter than vegetative stems, with larger sheaths, fleshy, ephemeral. 2n =ca. 216.
Phenology: Cones maturing in early spring.
Habitat: Roadsides, riverbanks, fields, marshes, pastures, tundra
Elevation: 0–3200 m

Discussion
Among the many infraspecific taxa that have been named in this species, Equisetum arvense var. boreale (Bongard) Ruprecht 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).
Selected References
None.
Lower Taxa
