    Habit
    Perennial. Ligule a fringe of hairs. Leaf-blades linear, or lanceolate; 30-60 cm long; 1.5-2.5 mm wide. Leaf-blade surface scaberulous; rough adaxially; glabrous, or pilose; with tubercle-based hairs. Leaf-blade margins cartilaginous; scabrous. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Peduncle pubescent above. Panicle spiciform; linear; 10-20 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis villous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets pedicelled; 1 in the cluster. Companion sterile spikelets pedicelled; 4 in the cluster. Involucre composed of bristles; oblong; 9-12 mm long; base obtuse. Involucral bristles deciduous with the fertile spikelets; numerous; with an outer whorl of thinner bristles; with one conspicuously longer bristle; 20-28 mm long; terete; flexible; ciliate. Pedicels 0.5-1 mm long.
    Sterile
    Companion sterile spikelets well-developed; male; oblong; laterally compressed; 9-10 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; 8-9 mm long; keeled; 1-3 -veined; obtuse, or acute. Companion sterile spikelet lemmas 2; exserted from glumes; 6-8 mm long.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 9-10 mm long; falling entire; deciduous with accessory branch structures. Companion sterile spikelets well-developed; male; oblong; laterally compressed; 9-10 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; 8-9 mm long; keeled; 1-3 -veined; obtuse, or acute. Companion sterile spikelet lemmas 2; exserted from glumes; 6-8 mm long.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 9-10 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes one the lower absent or obscure; shorter than spikelet; thinner than fertile lemma. Upper glume ovate; 1-2 mm long; 0.1-0.2 length of spikelet; hyaline; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate, or ovate; 2-3 mm long; 0.33-0.5 length of spikelet; membranous; 0-1 -veined; without midvein, or with evident midvein; without lateral veins; acute. Fertile lemma ovate; 9-10 mm long; chartaceous; without keel; 5 -veined. Lemma surface scaberulous; rough above. Lemma margins flat. Lemma apex acuminate. Palea 1 length of lemma; coriaceous.
