Inflorescence a spike-like panicle, 2–6(–8) cm long, 4–6 mm wide; glumes 2–3.5 mm long, obtuse, hyaline at apex, connate only at base, hairy along keel and margins; lemma subequal to glumes, obtuse, glabrous, shining brown at maturity, margins usually free, occasionally connate in lower 1–1.5 mm; awn 3–7 mm long, geniculate, inserted about one-quarter above base of lemma; palea absent.

Native to much of the Northern Hemisphere and introduced throughout much of the Southern Hemisphere. In Victoria, a widespread species of wet or low-lying, open sites, particularly in the west, occasionally growing partly submerged and then the stems commonly long and rooting freely from nodes.
Alopecurus australis was described as an indigenous Australian species, but it is generally agreed that the plant represented by that name is not specifically distinct from A. geniculatus and was an early introduction into this country.
