Caespitose perennial with short rhizomes; culms up to 100 cm high, robust, erect or slightly decumbent; nodes exposed and bearded; internodes glabrous; leaf sheaths glabrous to pilose; ligule a scarious membrane up to 1.5 mm long; leaf laminas up to 15 cm long, linear-lanceolate, glabrous to pilose throughout. Racemes 1–15, digitate, sessile to subsessile, white-villous, the culm below the inflorescence glabrous; rhachis internodes and pedicels thinly pilose; the lowermost 1–6 spikelet pairs usually homogamous, male or neuter. Sessile spikelets elliptic-oblong; inferior glume pilose or rarely glabrous on the back below the middle, always with tubercle-based cilia (up to 6 mm long) along the margins and forming a transverse subapical fringe; superior glume slightly longer than the inferior, glabrous; inferior floret barren, the lemma hyaline; superior floret stipitiform, the lemma hyaline, without a palea; awn c. 30 mm long; anthers c. 2 mm long. Pedicelled spikelets c. 4 mm long, obovate-oblong.
