Information
Reed-like perennial from a creeping rhizome; culms 0.6–5 m. high, often robust, scaberulous or occasionally pubescent below the panicle; nodes brown. Leaf-blades 10–45 cm. long, 2–10(–15) mm. wide, hard, glaucous, often convolute, with a filiform tip. Panicle linear, often elongated, 6–40 cm. long; rhachis cylindrical with rounded ribs, with or without peduncle-stumps, scaberulous or sometimes pubescent; involucre enclosing 1 sessile spikelet, without a distinct stipe at the base; bristles glabrous, the longest 5–20 mm. Spikelets narrowly elliptic to narrowly ovate, 2–6 mm. long, acute to acuminate; lower glume up to 1 mm. long, usually obtuse; upper glume 1/8–1/4 as long as the spikelet, usually acute to acuminate, occasionally obtuse; lower lemma ♂ or barren, 3/4 to as long as the spikelet; upper lemma scarcely differing in texture from the lower.

Notes
The waterside reeds have been brought together, and treated here as a single polymorphic species. Within it there is a reticulum of local segregates, which intergrade to such an extent that subdivisions can be no more than arbitrary in the absence of firm guidance from ecological and cytological studies. P. trachyphyllum, with broad thin leaf-blades and black nodes, may key out here. There is also some similarity to P. monostigma Pilg., a W. African species with straggling geniculate culms, and a hairy rhachis with conspicuous peduncle-stumps.
