Morphology General Habit
Perennial. Rhizomes elongated; leptomorph. Culms erect, or arching; 600-800 cm long; 20 mm diam.; woody. Culm-internodes terete; thin-walled; 40-45 cm long; distally glabrous. Lateral branches dendroid. Branch complement three, or several; with subequal branches; thinner than stem. Culm-sheaths persistent; glabrous; hairy on margins; without auricles; glabrous on shoulders. Culm-sheath ligule 3-4 mm high. Culm-sheath blade linear, or lanceolate; reflexed; glabrous on surface. Leaf-sheaths 25 cm long; striately veined; glabrous on surface. Leaf-sheath oral hairs scanty; pale. Ligule an eciliate membrane, or a ciliolate membrane; 3-4 mm long; truncate, or obtuse. Leaf-blade base cuneate; with a brief petiole-like connection to sheath; petiole glabrous. Leaf-blades deciduous at the ligule; lanceolate; 5-30 cm long; 15-35 mm wide; mid-green and glaucous; with undersurface a different shade on either side of midrib. Leaf-blade venation with 8-12 secondary veins; with distinct cross veins.
Morphology Reproductive morphology Inflorescences
Inflorescence comprising only a few spikelets; comprising 1 fertile spikelets; subtended by a spatheole; embraced at base by subtending leaf. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-8 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 40-70 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes eventually visible between lemmas; pilose; hairy at tip.
Fertile
Spikelets comprising 5-8 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 40-70 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes eventually visible between lemmas; pilose; hairy at tip.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes two; persistent; similar; shorter than spikelet. Lower glume ovate; chartaceous; without keels. Lower glume apex acute. Upper glume ovate; chartaceous; without keels. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 9 mm long; chartaceous; without keel. Lemma apex acuminate. Palea 1 length of lemma; 2 -veined. Palea keels ciliolate. 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.
