Inflorescence of 20–50 secund lateral downward-oriented spikes, each 1–2 cm long and with 3–6 spikelets. Spikelets 4–5 mm long. Lemmas essentially hairless, awn-tipped, these falling with the lateral spike of spikelets; rudimentary florets 1 (Lavin in Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
