Lateral branches dendroid. Bud complement 1. Branch complement one; solitary; as thick as stem. Culm-sheaths persistent; glabrous; without auricles. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs setose. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate, or oblong; 17–25 cm long; 25–35 mm wide. Leaf-blade surface pubescent; densely hairy; hairy abaxially, or on both sides. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle.
Panicle open; oblong; 10 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 6–11 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. Rhachilla internodes 5 mm long; pubescent.
GLUMES Glumes persistent; dissimilar; shorter than spikelet; thinner than fertile lemma. Lower glume linear; 1–2 mm long; scarious; without keels. Lower glume apex acuminate. Upper glume lanceolate; 4–6 mm long; scarious; without keels; 3 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma ovate; 12–14 mm long; chartaceous; without keel; 13–15 -veined. Lemma lateral veins with cross-veins. Lemma margins ciliate; hairy above. Lemma apex acuminate. Palea 0.9 length of lemma; 13 -veined. Palea keels ciliate; adorned above; with 0.5 of their length adorned. Palea apex with excurrent keel veins. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 3; ovate; 2–2.5 mm long; veined; ciliate; obtuse. Anthers 6; 5 mm long. Stigmas 3.
FRUIT Caryopsis with adherent pericarp; apex unappendaged.
DISTRIBUTION Europe: northern. Asia-temperate: eastern Asia. Australasia: New Zealand.
