Morphology General Habit
Perennial; caespitose. Culms erect, or geniculately ascending; robust; 100-250 cm long; 4-10 mm diam.; 6-8 -noded. Culm-internodes terete; distally glabrous. Leaf-sheaths loose; keeled; pilose; with tubercle-based hairs. Ligule an eciliate membrane; 2-7 mm long; obtuse. Leaf-blades 30-60 cm long; 4-10 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade surface glabrous; hairless except near base. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; fasciculate; 100-150 cm long; open; with principal spatheoles embracing a compact fascicle of racemes, each subtended by a subsidiary bract (4-6 racemes). Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate; 4-9 cm long; scarious; without tubercles; pilose. Racemes 1; single; cuneate; bearing few fertile spikelets; bearing 1 fertile spikelets on each. Rhachis fragile at the nodes. Spikelets in threes (basal paired). Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 2 in the cluster. Pedicels oblong; 1 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; with normal internodes; subsessile; male; lanceolate; 25-40 mm long; larger than fertile. Basal sterile spikelet glumes tuberculate; setose; attenuate; lower glume muticous. Companion sterile spikelets well-developed; male; lanceolate; 25-40 mm long; longer than fertile; separately deciduous. Companion sterile spikelet callus linear; 3-5 mm long. Companion sterile spikelet glumes herbaceous; pilose; attenuate. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 10 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus oblong; pubescent; attached obliquely.
Sterile

Basal sterile spikelet glumes tuberculate; setose; attenuate; lower glume muticous. Companion sterile spikelets well-developed; male; lanceolate; 25-40 mm long; longer than fertile; separately deciduous. Companion sterile spikelet callus linear; 3-5 mm long. Companion sterile spikelet glumes herbaceous; pilose; attenuate.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 10 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus oblong; pubescent; attached obliquely.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume ovate; 1 length of spikelet; coriaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface hirsute. Upper glume oblong; coriaceous; 3 -veined.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline; 0 -veined; without midvein; without lateral veins. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn apical; geniculate; 20-40 mm long overall; with twisted column. Column of lemma awn pubescent. Palea absent or minute.
