Description: Native, warm season, perennial, tufted grass to 120 cm tall. Fresh leaves are hairless and often lemon-ginger scented when crushed. Flowerheads are narrow spatheate panicles 10-45 cm long; clusters of short, nearly hairless, paired branches that bend downwards as they mature, giving the flowerhead a barbed-wire appearance. Spikelets are paired and awnless; one unstalked; the other stalked. Flowers in summer. Found in low fertility situations such as roadsides, native pastures, woodlands and forests. Very drought tolerant, but readily frosted. Native biodiversity. An indicator of low fertility soils. Production and feed quality is low to moderate, and palatability is highly variable. Unresponsive to fertiliser and its abundance declines with increasing fertility. Abundance declines under frequent close grazing. Persists best under rotational grazing and/or light stocking; especially if it includes a rest from grazing in early autumn. Date: 6 November 2015, 17:57. Source: Cymbopogon refractus spikelet14.
