Racemes 1–5, subdigitate, shortly pedunculate, the peduncles and the culm below the inflorescence pubescent; rhachis internodes and pedicels usually pilose on one side, glabrous on the other; the lowermost 1–6 spikelet pairs usually homogamous, male or neuter. Sessile spikelets 2–5 mm long, obovate; inferior glume slightly concave, pilose below the middle, glabrous or shortly pilose above the middle towards the margins and apex, narrowly winged towards the apex; superior glume as long as the inferior, glabrous except for the often shortly ciliate keel and margins; inferior floret barren, the lemma hyaline; superior floret stipitiform, the lemma hyaline; awn c. 22 mm long, minutely pubescent on both column and bristle; anthers c. 2 mm long.
