A valuable pasture grass of the drier inland areas, both vegetative and floral
parts being readily eaten by stock, but commonly increasing under heavy
stocking. Sometimes indicates overgrazing or disturbance. Exhibits weedy
behaviour in towns and on roadsides in less arid areas.
distributed through inland areas of all mainland states, and occurring near to
the coast and on off-shore islands above 24°S. Recorded growing on many soil
types but most often on sand and in seasonally wet areas such as creek-banks
and flood-plains; tolerates saline and swampy conditions and appears after
flooding; in grassland (sometimes with Astrebla) or shrubland, mulga,
open forest, cleared land; erect when with other grasses, prostrate on bare
ground; flowers normally Dec.-June, Oct.
