Branch complement three, or several; in a clump; with 1 branch dominant; thinner than stem. Culm-sheaths deciduous; 20 cm long; 0.6 times as long as wide; pubescent; with appressed hairs; with dark brown hairs; auriculate; with 5-10 mm high auricles; setose on shoulders; shoulders with curved hairs; shoulders with 3-5 mm long hairs. Culm-sheath ligule 2-15 mm high; fimbriate. Culm-sheath blade triangular; deciduous; 10 cm long; 200 mm wide. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath oral hairs setose; erect, or spreading; 2-5 mm long. Ligule a ciliolate membrane; 0.5-1 mm long; pubescent on abaxial surface; truncate. Leaf-blade base with a brief petiole-like connection to sheath; petiole glabrous.
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; with 1-keeled prophylls; leafless between clusters.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-8 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 32 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; 1-2 mm long.
Fertile
Spikelets comprising 5-8 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 32 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; 1-2 mm long.

Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 5-19 mm long; purple; without keel; 11-13 -veined. Lemma apex acute. Palea 4-15 mm long. Palea keels wingless; ciliate; adorned all along; with hairs 0.5-1 mm long. Palea surface scaberulous (on flanks); pilose; hairy on margins; hairy above. Palea apex entire, or dentate; 2 -fid; acute. Apical sterile florets resembling fertile though underdeveloped, or distinct from fertile; if distinct rudimentary.
