Morphology General Habit
Perennial; culms solitary. Rhizomes elongated; scaly. Culms erect; 90-250 cm long; 5-8 mm diam. Culm-internodes 5-20 cm long. Culm-nodes bearded. Leaves cauline. Leaf-sheaths glabrous on surface. Ligule a ciliolate membrane; 0.5-1 mm long. Leaf-blades 20-80 cm long; 10-30 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes few, or numerous; 8-40; digitate; drooping, or ascending; 10-35 cm long. Central inflorescence axis 4-10 cm long. Rhachis tough; subterete; glabrous on surface. Rhachis internodes filiform; 4-8 mm long. Spikelets in pairs. Fertile spikelets pedicelled; 2 in the cluster. Pedicels filiform; unequal; 1.5-7 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5-6 mm long; 0.8-1 mm wide; falling entire. Spikelet callus bearded; base truncate. Spikelet callus hairs white; 2-4 length of spikelet.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5-6 mm long; 0.8-1 mm wide; falling entire. Spikelet callus bearded; base truncate. Spikelet callus hairs white; 2-4 length of spikelet.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; chartaceous; much thinner above; dark brown; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume surface flat. Lower glume margins ciliate (hairs to 15mm). Lower glume apex entire; acuminate. Upper glume lanceolate; chartaceous; much thinner above; without keels; 3 -veined. Upper glume margins ciliate. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 0.8 length of spikelet; hyaline; 3 -veined; ciliate on margins; acute. Fertile lemma lanceolate; 3.5-4.5 mm long; hyaline; without keel; 0-1 -veined. Lemma apex dentate; 2 -fid; muticous, or mucronate. Palea 0.5 length of lemma. Palea apex ciliate.
Morphology Reproductive morphology Flowers
Anthers 3; 2-2.5 mm long.
Distribution
Asia-temperate: Soviet far east, China, and eastern Asia.
