Status:
Native to coastal western and southern Europe. Naturalised in Victoria, New South Wales, Queensland, South Australia and Western Australia.

Tufted annual grass with erect to spreading, smooth to softly hairy (hairs to 0.3 mm long) stems to 50 cm long and velvety-hairy, flat, leaves 4-15 cm long and 1.5-4 mm wide; ligule membranous, 0.5 mm long.

Inflorescence, a compact, much bristled, semi-flattened spike, 1.5-5 cm long, containing spikelets in groups of three. Each spikelet is composed of a single, central and awned floret and two bristles. A number of species have a similar inflorescence appearance (see notes on spikelet differences).

Habitat:
A colonizer of disturbed low-lying situations associated with pasture plants and some native communities. Widespread in saline areas.
