    Inflorescences
    Inflorescence a panicle. Panicle open; lanceolate, or ovate; 3-8 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 5-7.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.3 mm long; pubescent; obtuse.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 5-7.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.3 mm long; pubescent; obtuse.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 2.5-6 mm long; 0.5-0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex acuminate; mucronate. Upper glume cuneate; 5-7.5 mm long; 1.2-1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume lateral veins absent. Upper glume apex acuminate; mucronate.
    Florets
    Fertile lemma elliptic; subterete; 4-5 mm long; coriaceous; without keel; 3 -veined. Lemma margins convolute; covering most of palea. Lemma apex rostrate; with a short cylindrical neck; with this appendage 0.5 mm long; awned; 3 -awned. Principal lemma awn 3-branched; with 6-8 mm long limb; without a column; persistent. Lateral lemma awns gyrate; 6-8 mm long; subequal to principal. Palea 0.1 length of lemma; without keels.

    Leaf-sheaths striate, glabrous, the basal somewhat lax, persistent, breaking up into fibres, forming a dense tuft at the base of the culms, the upper somewhat tighter.
    Ligules
    Ligule a short-ciliolate rim; auricles barbate; collar glabrous.

    Inflorescences
    Panicle 8 x 4 cm., ovate-lanceolate in outline, long-exserted, lax but not much branched; axis smooth, more or less angular, scaberulous upwards; branches 2-nate or 3-5-partite, capillary, somewhat flexuous, naked in the lower 1/2, scaberulous, the lower up to 3 cm. long.
    Spikelets
    Spikelets brownish-purple to deep purple, contracted towards the ends of the branches.
    Glume
    Glumes subequal to unequal, glabrous or scabrous on the keels; the inferior usually 2·5-5 mm. long, lanceolate-ovate, 3-nerved, often 3-keeled, gradually or abruptly tapering into a short awn c. 1 mm. long; the superior usually 4·5-6 mm. long, linear-lanceolate, mucronate, or with a short awn up to 1 mm. long.
    Lemma
    Lemma 3·5-5 mm. long, slightly keeled, glabrous, smooth in the lower part, more or less scaberulous towards the apex, prolonged into a short beak up to 0·7 mm. long; callus 0·2-0·3 mm. long, obtuse, short-barbate; awns subequal, scabrid, usually slightly contorted at the base; the central 7-8 mm. long, the lateral ones 5-6 mm. long; articulation absent.
