Glumes unequal or subequal, obtuse, 1-nerved, somewhat keeled, ultimately gaping. Lemma equalling or exceeding glumes, truncate, finely and densely scaberulous to almost smooth, 5-nerved, with a minute dorsal awn attached immediately below the apex, sometimes scarcely separated from the lemma and not or scarcely exceeding it; callus short, bearded with rather stiff hairs 0.3–1.2 mm long.
