Leaves with sheath mostly glabrous; ligule a ciliate rim; blade to 5 mm wide. Leaf sheaths closely encircling the stem; pedicellate spikelets usually 5–7 mm long. Leaf sheaths closely encircling the stem; pedicellate spikelets usually 5–7 mm long.
Raceme 6–14 cm long, often slightly curved, axillary racemes may form at lower nodes, spikelets falling with rachis internodes. Sessile spikelets 6–10 mm long. Lower glume tapering into a very variable point, acute, acuminate or hooked, faintly 5–7-nerved; upper ± fused to rachis. Lower lemma 2-nerved, sterile, without a palea; upper nerveless, with a small nerveless palea. Pedicellate spikelets 5–10 mm long, often slightly longer and more acuminate than the sessile spikelets.
