Lateral branches dendroid. Culm-sheaths deciduous; hispid; with dark brown hairs; auriculate; setose on shoulders; shoulders with 12 mm long hairs. Culm-sheath blade linear, or lanceolate; reflexed. Leaf-sheaths pubescent. Leaf-sheath oral hairs setose. Leaf-sheath auricles falcate. Ligule a ciliolate membrane. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.5–1 cm long. Leaf-blades oblong; 18–28 cm long; 30–40 mm wide. Leaf-blade venation with 14 secondary veins. Leaf-blade surface scabrous; rough adaxially; glabrous, or puberulous; hairy abaxially. Leaf-blade margins scaberulous. Leaf-blade apex attenuate; antrorsely scabrous.

INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in stellate clusters; 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; without rhachilla extension. Spikelets linear; subterete; 15–16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes elongated below proximal fertile floret.

GLUMES Glumes several; 3–4 empty glumes; persistent; shorter than spikelet. Upper glume lanceolate, or ovate; chartaceous; without keels. Upper glume mucronate.

FLORETS Fertile lemma oblong, or ovate; 8–11 mm long; chartaceous; without keel. Lemma surface puberulous. Lemma margins convolute. Lemma apex acute; muticous, or mucronate. Principal lemma awn 0.5–1 mm long overall. Palea tightly convolute around flower; 12–15 mm long; chartaceous; without keels. Palea apex awned; awns 2–3 mm long.

FLOWER Lodicules absent. Anthers 6; 4 mm long; anther tip smooth. Filaments united in a tube. Stigmas 3. Styles 12–15 mm long. Ovary with a steeple-like appendage.

FRUIT Caryopsis with free brittle pericarp.

DISTRIBUTION Asia-tropical: Indo-China.
