Culm-nodes pubescent (brown). Lateral branches dendroid. Branch complement one, or two, or three; in a clump; with 1 branch dominant; thinner than stem. Culm-sheaths deciduous; glabrous. Culm-sheath ligule 1-2 mm high; ciliolate. Culm-sheath blade triangular; erect; hispid; acute. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath oral hairs setose; 4-6 mm long; pale. Leaf-sheath auricles erect. Ligule an eciliate membrane. Leaf-blade base broadly rounded; with a brief petiole-like connection to sheath; petiole 0.3-0.5 cm long. Leaf-blades lanceolate; 7-18 cm long; 10-18 mm wide. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; dense; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
Fertile
Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes several; 2-3 empty glumes; persistent; similar; shorter than spikelet.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 8-9 mm long; without keel; 15 -veined. Lemma margins ciliolate. Lemma apex acute; mucronate. Palea oblong; 1 length of lemma. Palea keels wingless; ciliate. Apical sterile florets resembling fertile though underdeveloped.
