Plants female only, but apomictic and producing viable seed. Culms to 4.5 m high, normally at least twice as high as the basal tusosck; nodes glabrous, mostly concealed by leaf-sheaths; leaves bright green, glabrous; sheath often densely sericeous; blade to 1.5 m long and 2 cm wide, usually not turned so that the scabrous abaxial surface remains lowermost, flat, keeled beneath, coarsely scabrous on margins and nerves on lower (abaxial) surface, ; ligule a dense row of fine, silky hairs to 4 mm long. Inflorescence a dense, plume-like panicle to 80 cm long, purplish (but bleaching as it ages). Spikelets 3–5-flowered, 10–15 mm long, veins of glume, rachilla segments and usually lemmas purple; glumes hyaline, narrow-acuminate, 8–13 mm long, subequal or the lower shorter by up to 2 mm; florets narrow-acuminate, 8–12 mm long, lemma narrowly tapered with fine, awn-like apices, hyaline, smooth, plumose; palea 3–5 mm long, hyaline, glabrous. Flowers Jan.–Mar.
*EGL, *GipP, *Glep, *HSF, *OtP, *VRiv, *VVP. Also naturalised in Tas., southern Africa. Native to South America. Cultivated for its ornamental purplish inflorescences, but recently noted as being naturalised in damp areas on the Bellarine Peninsula, Lysterfield, Morwell and Nowa Nowa.
A very invasive species in Tasmania, due to its ability to produce large amounts of viable seed without the need for fertilization. Noted as spreading significantly in Victoria in recent years.
