HABIT Perennial; caespitose. Rhizomes elongated. Culms erect; 70–120 cm long. Culm-internodes smooth; distally glabrous. Culm-nodes bearded. Ligule a ciliolate membrane. Leaf-blades 15–20 cm long; 5–10 mm wide. Leaf-blade surface glabrous. Leaf-blade margins scaberulous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 5–7; digitate; 15–18 cm long. Rhachis tough; subterete. Rhachis internodes filiform.

Spikelets in pairs. Fertile spikelets pedicelled; 2 in the cluster. Pedicels filiform; unequal; 1 mm long, or 3.5 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5 mm long; falling entire. Spikelet callus bearded; base truncate. Spikelet callus hairs white; 6 mm long; 1.1–1.2 length of spikelet.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; chartaceous; without keels; 3 -veined. Lower glume surface flat; villous. Lower glume apex acuminate. Upper glume lanceolate; 1 length of spikelet; chartaceous; without keels; 5 -veined. Upper glume surface villous. Upper glume apex acuminate.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 3.5 mm long; 0.75 length of spikelet; hyaline; acute. Fertile lemma lanceolate; 4 mm long; hyaline; without keel; 1 -veined. Lemma apex awned; 1 -awned. Principal lemma awn straight; 3 mm long overall; clearly exserted from spikelet. Palea linear; 0.66 length of lemma.

FLOWER Anthers 3; 2.5 mm long.

DISTRIBUTION Asia-temperate: eastern Asia.
