Culm-internodes terete; hollow; 25–35 cm long; distally pruinose. Lateral branches dendroid; arising from mid culm. Branch complement several; in a clump; with subequal branches. Culm-sheaths deciduous; 8–9 cm long; glabrous, or pilose; hairy at the base; with tawny hairs; hairy on margins; truncate at apex; auriculate; with obtuse auricles; with 1 mm high auricles; ciliate on shoulders; shoulders with 4 mm long hairs. Culm-sheath ligule ciliate. Culm-sheath blade triangular; as wide as sheath at base; erect; 5–7.5 cm long; 30–60 mm wide; pubescent. Leaf-sheath oral hairs ciliate; 5–7 mm long. Leaf-sheath auricles absent. Ligule an eciliate membrane; 0.4 mm long. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 13–20 cm long; 11–17 mm wide. Leaf-blade surface glabrous. Leaf-blade margins ciliate. Leaf-blade apex acuminate.

INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in untidy tufts; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.

Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 11–19 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes two; persistent; shorter than spikelet. Lower glume ovate; 8 mm long. Lower glume apex acuminate. Upper glume ovate; 8 mm long; chartaceous. Upper glume apex acuminate.

FLORETS Fertile lemma ovate; 11 mm long; chartaceous; without keel. Lemma apex attenuate. Palea 12 mm long; chartaceous; without keels. Palea apex dentate; 2 -fid. Apical sterile florets 1 in number; rudimentary.

FLOWER Lodicules 3; 4 mm long; glabrous. Anthers 6; 5 mm long; yellow; anther tip apiculate. Stigmas 3. Ovary with a steeple-like appendage; glabrous.
