Notes. Morphologically similar to S. elongatus, differing by its distinctly fibrous base.
Endemic; fairly widely distributed in the arid regions, mainly in central Australia. Found in or near places of accumulated moisture, creek beds, moisture depressions and watercourses. It is a resurrection grass, reviving after dehydration (Lazarides (1992) as Sporobolus species undescribed; flowers all year, in response to rain.
