Scattered in central to south-western Victoria, often in near-coastal and somewhat saline sites, but occasionally occurring on bare soil in fairly intact native grassland and grassy woodland.
Previously included with the very similar Tribolium acutiflorum (Nees) Renvoize which appears to be much less common in Victoria.
