Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 400-800 cm long; 30-60 mm diam.; woody; with root thorns from the nodes. Culm-internodes terete; 25-34 cm long. Culm-nodes glabrous. Lateral branches dendroid. Branch complement several. Culm-sheaths deciduous; glabrous; auriculate; with equal auricles; ciliate on shoulders. Culm-sheath ligule 8 mm high; dentate. Culm-sheath blade triangular. Leaves cauline. Leaf-sheath oral hairs setose; 5-10 mm long. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.5-1 mm long. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 6.5-20 cm long; 5-18 mm wide. Leaf-blade venation with 10-12 secondary veins. Leaf-blade surface pubescent; hairy abaxially. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 7-8 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 40-50 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; 3.5-4 mm long; pubescent.
Fertile
Spikelets comprising 7-8 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 40-50 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; 3.5-4 mm long; pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes both absent or obscure, or one the lower absent or obscure; 0-1 empty glumes; persistent; shorter than spikelet.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 10-11 mm long; without keel. Lemma surface glabrous. Lemma apex acute. Palea 1.1 length of lemma. Palea keels ciliolate; adorned above. Palea surface pubescent. Apical sterile florets resembling fertile though underdeveloped.
