Culms scandent; 800–1200 cm long; 10–45 mm diam.; woody; with root thorns from the nodes.
Culm-internodes semiterete; thin-walled, or thick-walled; scaberulous.
Lateral branches dendroid.
Bud complement 1.
Culm-sheaths 4.5–5 times as long as wide; glabrous.
Culm-sheath ligule 1 mm high.
Culm-sheath blade triangular; demarcated but persistent; erect; 6 cm long; 20 mm wide.
Leaves 5–13 per branch.
Leaf-sheaths glabrous on surface; outer margin hairy.
Leaf-sheath oral hairs ciliate; 2–3 mm long.
Ligule an eciliate membrane; 1–1.2 mm long.
Collar with external ligule.
Leaf-blade base truncate, or cordate; with a brief petiole-like connection to sheath; petiole 0.3–0.6 cm long; petiole glabrous.

Leaf-blade apex acuminate.

INFLORESCENCE:

Synflorescence bractiferous; globose; axis 0.2–0.7 cm long; dense; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets.

FERTILE SPIKELETS:

Spikelets comprising 5–7 fertile florets; with diminished florets at the apex.
Spikelets linear; laterally compressed; 40–60 mm long; 4–6 mm wide; breaking up at maturity; disarticulating below each fertile floret.
Rhachilla internodes obscured by lemmas.

FLORETS:

Fertile lemma lanceolate, or ovate; 17–23 mm long; coriaceous; light brown; shiny; without keel; 15–20 -veined.
Lemma lateral veins obscure; with cross-veins.
Lemma apex acute.
Palea 13–17 mm long.
Palea keels winged; conspicuously winged.
