Vegetative morphology. Plants softly erect. Plants solitary, or loosely tufted. Plants with non-flowering shoots less common than flowering shoots. Plants with leaves along the stems. Plants with tillering leaves 1/4 to 1/3 the length of the culms (?). Plants with shoots intravaginal. Culms (40–)60–80 cm tall. Culms 1.3–1.7(–3) mm wide. Culms geniculate (slightly). Culms internodes glabrous. Culms nodes (3–)4. Uppermost culms nodes in mid 1/3 of the culm. Sheaths shorter than the internode. Sheaths glabrous. Sheaths open more than half their length. Sheaths not conspicuous at the base of the plant. Sheaths remaining entire, not conspicuously splitting between the veins. Auricles claw-like. Auricular cilia absent. Ligules 0.3–0.6(–1) mm long. Ligules margins ciliolate, or without cilia. Ligules apices entire, or erose. Leaf blades more or less lax. Leaf blades linear. Leaf blades flat, or involute. Leaf blades adaxial lateral longitudinal ridges distinctly raised. Leaf blades (2.5–)6–10(–30) cm long. Leaf blades 1.5–2.5(–4) mm wide. Leaf blades adaxial surfaces glabrous, or with trichomes. Leaf blades adaxial surfaces glabrescent. Leaf blades abaxial surfaces glabrous. Flag leaves blades 2.5 cm long. Flag leaves blades much shorter than the sheath. Veins 10–14. Ribs 8–13(–15).
Floral morphology. Inflorescences linear, or narrowly lanceolate. Inflorescences spiciform (but long). Inflorescences 13–17(–26) cm long. Inflorescences branches 2–5 cm long. Inflorescences lowest internodes 3–5 cm long. Inflorescences branches at the lowest nodes 2, or 1. Inflorescences branches stiff. 1 fertile spikelets on the longest branches. Inflorescences branches flattened and ribbon-like. Inflorescences branches scabrous on the angles, or glabrous. Inflorescences branches vestiture sparse. Pedicels 1.5–4(–15) mm long. Spikelets aggregated towards the ends of the branches (branches with only one spikelet). Spikelets 12–16 mm long. Spikelets (2.5–)3–5 mm wide. Spikelets purplish, or brown (with greenish). Spikelets lanceolate, or narrowly lanceolate. Florets 3–4. Glumes membranous, or herbaceous. Glumes glabrous. Glumes margins not ciliate. Glumes margins narrowly membranous. Glumes apices accuminate. First glume narrowly lanceolate. First glume 4–5(–7) mm long. First glume 2–3 nerved. First glume 0.7–0.8 as long as second glume. Second glume lanceolate. Second glume 5.2–6.7 mm long. Second glume 4–5 nerved. Second glume shorter than first lemma. Second glume 0.4–0.5 as long as the spikelets. Rachilla internodes 1.8–2.2 mm long. Rachilla internodes glabrous. Rachilla internodes flattened, or cylindrical (slightly). Rachilla internodes narrow. Rachilla internodes straight. Lemmas 7.5–9(–10) mm long. Lemmas broadly lanceolate. Lemmas subcoriaceous. Lemmas somewhat dorsally compressed. Lemmas veins 5. Lemmas nerveless in dorsal view or sometimes with only the centre vein distinct. Lemmas glabrous, or with trichomes. Lemmas scabrous. Lemmas trichomes on the upper portion. Lemmas upper margins narrowly membranous. Lemmas apices notched (slightly). Lemmas apices accuminate. Lemmas apices awns 7–15 mm long. Lemmas apices awns about as long as the lemmas, or much longer than the lemmas (usually). Paleas 7.5–8.5 mm long. Paleas 1–1.2 mm apart. Paleas equal or subequal to the lemmas. Paleas keels scaberulous. Paleas inter-keel regions glabrous. Anthers 2.5–3 mm long. Ovary apices glabrous (immature).
Ecology. Flowering time July. On grassy places, along forests edges; 2600–2800 m. Distribution. Southwestern China: Sichuan, Yunnan.
