In the following key, spikelet and scale lengths do not include the awns (when present). Reference: Michael (2003).
1b. Panicle branches (1–) 2–10 cm long, variable in number but often crowded, sometimes the longer branches with secondary branches; leaf blades 5–30 mm wide (sometimes narrower in small forms of E. crus-galli); spikelets 2.5–5 mm long
2b. Lower lemmas usually awned; upper lemmas hardly, if at all, exceeding the upper glumes in length and width, primarily concealed
3b. Sheaths glabrous; lower nodes glabrous or sparsely pubescent with short hairs
