Aerial stems monomorphic, green, branched or occasionally unbranched, 2–70 cm; hollow center 2/3–4/5 stem diam. Sheaths somewhat elongate, 3.5–8 × 2.5–6 mm; teeth dark, 7–14, narrow, 1–3 mm. Branches mostly from midstem nodes, ascending to spreading, solid; ridges 4–5; valleys channeled; proximal whorls with 1st internode of each branch equal to subtending stem sheath, distal whorls with 1st internode of each branch longer than stem sheath; sheath teeth attenuate.
Phenology: Cones maturing in early summer, but misshapen spores not shed.
Habitat: Ditches, stream banks, wet meadows
Elevation: 0–1000 m

Discussion
Equisetum × litorale is a hybrid between E. arvense and E. fluviatile. It should be expected where the parents coexist. This hybrid has been mistaken for Equisetum palustre; the solid branches with long first internodes and channeled valleys distinguish it from that species.
Selected References
None.
Lower Taxa
None.
