A genus sometimes confused with Phleum. In addition to unawned glumes and awned lemmas, Alopecurus has appressed-ascending spikelets. Phleum, on the other hand, has awned glumes, unawned lemmas, and spreading to reflexed spikelets (except for the apical ones, which are ascending). Reference: Crins (2007).
1a. Glumes 4–6 mm long, acute to acuminate and firm at the apex [Fig. 185]; anthers 2.2–3.5 mm long
1b. Glumes 2–3.2 mm long, blunt and scarious at the apex [Fig. 184]; anthers 0.5–2 mm long
3b. Plants annual or short-lived perennial, erect or decumbent at base, usually not rooting from the lower nodes; glumes 2–2.7 mm long; anthers 0.3–1 mm long; inflorescence 3–5 mm thick
