Morphology General Habit
Perennial. Culms erect; robust; 300-500 cm long; 10-15 mm diam. Culm-internodes solid; distally glabrous. Leaf-sheaths loose; mostly shorter than adjacent culm internode; keeled; striately veined; smooth; glabrous on surface. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades 50-100 cm long; 7-15 mm wide. Leaf-blade midrib widened. Leaf-blade surface scabrous; glabrous. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; paniculate. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate; 2-3.5 cm long; scarious; without tubercles; glabrous. Racemes 1; single; oblong; 1.5-2 cm long; bearing few fertile spikelets; bearing 2-3 fertile spikelets on each. Rhachis fragile at the nodes. Spikelets in pairs. Fertile spikelets sessile; 2-3 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels oblong; 0.5 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; with normal internodes (between them); subsessile; persistent; male; lanceolate, or oblong; 10-12 mm long; larger than fertile. Basal sterile spikelet glumes tuberculate; hirsute; with tawny hairs; acuminate; lower glume muticous. Companion sterile spikelets well-developed; male; lanceolate, or oblong; 10-12 mm long; longer than fertile; deciduous with the fertile. Companion sterile spikelet callus oblong; 1.5-2 mm long. Companion sterile spikelet glumes tuberculate; pilose. Companion sterile spikelet lemmas 2; enclosed by glumes; muticous. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; 7-9 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus oblong; 2 mm long; bearded; base obtuse; attached obliquely. Spikelet callus hairs tawny.
Sterile

Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; coriaceous; dark brown; without keels. Lower glume surface flat; pubescent. Lower glume hairs tawny. Lower glume apex acute. Upper glume oblong; coriaceous; 3 -veined.
Morphology Reproductive morphology Flowers Florets
