Tufted perennial, up to 2.0(-2.4) m high, shortly rhizomatous, sometimes rooting at lower nodes; leaves mainly cauline. Leaf blade 150-480 x 5-35(-45) mm, cordate or straight at base. Inflorescence an open panicle, branches usually with clavate hairs. Spikelets 3.5-5.0(-5.5) mm long, dorsiventrally compressed; glumes unequal; lower glume 1/2-2/3 length of spikelet, separated by a short internode from rest of spikelet; upper glume 7-nerved, as long as spikelet. Florets 2; lower floret male, lemma 5-nerved, palea well developed; upper lemma indurated, pale, dull or shiny, entire, margins only clasping edges of palea. Flowering time Sept.-Apr.
Perennial, shortly rhizomatous and tufted (sometimes rooting at lower nodes), up to 2 m high. Leaf blades 150-480 mm long, 5-35(-45) mm wide, leaves mainly cauline, cordate or straight at base. Culms slender or robust, branched or unbranched. Spikelets 3.5-5.0 (-5.5) mm long. Inflorescence branches usually with clavellate hairs; lower glume half to two-thirds the length of spikelet, separated by a short internode from rest of spikelet; upper glume 7-nerved; lower floret male, lemma 5-nerved and palea well developed; female-fertile (upper) lemma pale, dull or shiny.
Tufted perennial to 2000-2400 mm high; rhizome short, sometimes rooting at lower nodes; leaves mainly cauline; culm slender or robust, branched or unbranched. Leaf blade 150-480 x 5-35(-45) mm, cordate or straight at base. Inflorescence branches usually with clavate hairs. Spikelet 3.5-5.0(-5.5) mm long; lower glume 1/2-2/3 the spikelet length, separated by a short internode from rest of spikelet; upper glume 7-nerved; lower floret male, lemma 5-nerved, palea well developed; upper lemma pale, dull or shiny. Variable in size, hairiness and habitat.
Perennial; up to 2 m high; shortly rhizomatous; sometimes rooting at lower nodes. Culms slender or robust; branched or unbranched. Leaf blades 150-480 x 5-35(-45) mm; leaves mainly cauline; cordate or straight at base. Flowers: panicle with branches usually with clavellate hairs; spikelets 3.5-5.0(-5.5) mm long; lower glume 1/2-2/3 length of spikelet; separated by a short internode from rest of spikelet; upper glume 7-nerved; lower floret male; lemma 5-nerved and palea well developed; upper female-fertile lemma pale; dull or shiny.
Panicle 10–40 cm. long, ovate to oblong, the primary branches stiff and usually ascending, rarely spreading, secondary branches usually very short, antrorsely scaberulous, pilose and clavellate-hairy or glabrous.
Inferior glume broadly ovate, 1/2–2/3the length of the spikelet, 5–7-nerved; superior glume 7-nerved, as long as the spikelet.
Leaf laminae 15–48 × 0.5–3.5(4) cm., linear to narrowly lanceolate, cordate or amplexicaul at the base, acuminate.
Like P. coloratum but spikelets 3.5-5.5 mm long, panicle branches with clavellate hairs.
Tufted or shortly rhizomatous perennial; culms slender or robust, 70–250 cm. high.
Spikelets 3.5–5(5.5) mm. long, oblong, glabrous, obtuse.
Inferior lemma 5-nerved, male, its palea well developed.
Superior lemma and palea dull or shining.
