Morphology General Habit: Perennial. Rhizomes elongated; leptomorph. Culms erect; 20-60 cm long; 1-2 mm diam.; woody. Culm-internodes terete; thin-walled; distally pubescent. Culm-nodes pubescent. Lateral branches lacking, or sparse. Culm-sheaths puberulous; with reflexed hairs. Culm-sheath blade lanceolate; erect; 0.5 cm long. Leaf-sheaths puberulous. Leaf-sheath oral hairs setose. Ligule an eciliate membrane, or a ciliolate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 15-20 cm long; 15-25 mm wide; mid-green and yellowish green; variegated (striped). Leaf-blade surface pubescent; densely hairy; hairy on both sides. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences: Inflorescence comprising only a few spikelets; comprising 1-3 fertile spikelets. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets: Spikelets comprising 6-8 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 40-50 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile: Spikelets comprising 6-8 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 40-50 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume: Glumes one the lower absent or obscure; persistent; shorter than spikelet. Upper glume lanceolate; 10-23 mm long; chartaceous; without keels; 5 -veined. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets: Fertile lemma elliptic; 13-15 mm long; chartaceous; without keel; 7 -veined. Lemma lateral veins with cross-veins. Lemma apex acuminate. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers: Lodicules 3. Anthers 3. Stigmas 3.
Morphology Reproductive morphology Fruits: Caryopsis with adherent pericarp; apex unappendaged.
Distribution: Asia-temperate: Caucasus and eastern Asia. Australasia: New Zealand.
