    Habit
    Perennial. Culms erect; 16-27 cm long. Culm-internodes antrorsely scabrous. Leaf-sheaths smooth, or scaberulous. Ligule an eciliate membrane, or a ciliolate membrane; 3-8.3 mm long; bilobed; acuminate. Leaf-blades convolute; 10-19 cm long; 2-3 mm wide. Leaf-blade venation with sclerenchyma strands widened to form a discontinuous subepidermal layer. Leaf-blade surface ribbed; grooved adaxially; scabrous; rough on both sides; glabrous, or puberulous; hairy adaxially. Leaf-blade margins ciliate.
    Inflorescences
    Inflorescence a panicle; shorter than basal leaves. Panicle spiciform; linear; 7-11 cm long; 0.5-1.5 cm wide. Primary panicle branches 2.5-3.5 cm long. Panicle axis smooth, or scaberulous. Panicle branches scabrous; with scattered hairs, or glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1.6-6.2 mm long; scaberulous, or scabrous.
    Spikelets
    Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 6-7.4 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; with elliptic scar. Floret callus hairs 0.6-1 mm long; 0.1-0.15 length of lemma.
    Fertile
    Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 6-7.4 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; with elliptic scar. Floret callus hairs 0.6-1 mm long; 0.1-0.15 length of lemma.
    Glume
    Glumes persistent; similar; reaching apex of florets; firmer than fertile lemma. Lower glume lanceolate; 6-7.4 mm long; 1 length of upper glume; membranous; yellow, or mid-green, or purple; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 6-7.4 mm long; membranous; yellow, or mid-green, or purple; 1-keeled; 3 -veined. Upper glume primary vein scaberulous. Upper glume apex acuminate.
    Florets
    Fertile lemma lanceolate; 5.2-5.8 mm long; membranous; yellow, or mid-green, or purple; without keel; 5 -veined. Lemma surface scaberulous; rough above. Lemma apex dentate; 3-4 -fid; awned; 1 -awned. Principal lemma awn dorsal; arising 0.33-0.5 way up back of lemma; geniculate; 5-6.8 mm long overall; clearly exserted from spikelet, or not or scarcely exserted from spikelet; with a straight or slightly twisted column, or with twisted column. Palea 3.2-4.6 mm long. Rhachilla extension 2.2-2.4 mm long; villous; with 3.2-3.8 mm long hairs.
    Flowers
    Lodicules 2. Anthers 3; linear; 1.8-2.6 mm long. Stigmas 2.
