Leaves are bright green, very fine and rough to the touch; erect when young, but drooping in larger plants. Ligules are short, white membranes 0.5–2.5 mm long. Flowerheads are open panicles to 25 cm long; they break off at maturity and blow along. Spikelets are 1-flowered and have 2 purplish glumes. Lemmas are 1.5-2 mm long and about as broad, with a nearly straight 2-3.5 cm long awn attached off-centre. Flowers in spring. A native of South America, it is mostly found on light soils in areas of disturbance (e.g. roadsides and overgrazed pastures), low productivity and/or ground cover. A Weed of National Significance, it readily invades any sort of grassy vegetation. Extremely poor feed value; animals forced to graze it may eventually starve to death. Plants and seed banks are long lived, but seedlings are susceptible to competition. Managed with a combination of methods: competitive pastures; windbreaks; minimising soil disturbance; machinery, fodder and livestock hygiene; cropping; physical removal; and registered herbicides.
