Roadsides, ditches, railroad rights-of-way, prairies, riverbanks, wet sandy terraces, sand dunes, and semi-open woodlands, more common in southern Wisconsin. Stems are normally unbranched or with a few short branches scattered at a few nodes rather than in a whorl. The internodes are smooth (lacking the rough tubercles of E. hyemale) relatively soft and often slight flattened on pressed specimens. Sheaths are gray green below, widened above with a band of black dots at the base of the teeth. Teeth drop quickly. Stems do not persist over winter. The cone apex is usually blunt
