Agrostis infirma arisan-montana
Blades up to 6 mm wide, slightly scaberulous. Panicle contracted, somewhat lobed, branches scabrous, the lowermost longest (2-)4-6.5 cm long. Spikelets 2-2.35 mm long. Lemma 1.5-1.7 mm long. Trichodium-net present but faint; callus hairs absent or very few, up to 0.2 m long; awn absent. Palea 0.5-0.75 mm long, 0.3-0.5 times as long as the lemma. Anthers 0.6-0.7 mm long, 0.38-0.47 times as long as the lemma.
