Vegetative morphology. Plants densely tufted. Plants with shoots intravaginal, or extravaginal. Rhizomes absent. Culms 15–60 cm tall. Culms nodes 1–2. Sheaths shorter than the internode. Sheaths glabrous (margins membranous). Auricles erect swellings, or absent. Leaf blades conduplicate. Leaf blades 10–20 cm long. Leaf blades adaxial surfaces with trichomes. Leaf blades adaxial surfaces scabrous. Leaf blades abaxial surfaces with trichomes. Leaf blades 0.45–0.55 mm wide. Ribs 5.

Floral morphology. Inflorescences loosely open. Inflorescences 6–10 cm long. Inflorescences branches 2–5 cm long. Inflorescences branches at the lowest nodes 1 (erect, or inclining ascendent). Inflorescences branches scabrous on the angles. Pedicels 5–10 mm long. Spikelets 8.5–11 mm long. Spikelets greenish, or purplish, or brown. Florets 3–6. Glumes glabrous. Glumes margins ciliolate. Glumes margins narrowly membranous. Glumes apices acute. First glume lanceolate. First glume 2–2.5 mm long. First glume 1 nerved. Second glume broadly lanceolate, or ovate. Second glume 3–4.5 mm long. Second glume 3 nerved. Rachilla internodes 1.8–2.2 mm long. Rachilla internodes pubescent. Lemmas 5.1–6.5 mm long. Lemmas with trichomes. Lemmas scabrous, or pubescent (rarely at lateral base). Lemmas apices awns present. Lemmas apices awns 2–3.5 mm long. Paleas equal or subequal to the lemmas. Paleas keels scaberulous. Paleas inter-keel regions scabrous, or pubescent. Anthers 1.5–2.5 mm long. Ovary apices hairy. Ovary hairs dense.
