erect, straight, 2–9.5(–17) cm long.

Spikelets sessile. Fertile spikelets many flowered, with at least 2 fertile
florets (5–18), comprising 5–18 fertile floret(s), with diminished florets at
the apex, linear or oblong, laterally compressed, 4–12(–22) mm long.

This species is termed a 'resurrection plant' as it is able to produce green
leaf from dry butts, and flowers and fruits in a very short time after rain.

 Morphologically variable in inflorecence form
and spikelet arrangement; further work is required to determine if 2 species
are represented.

Occurs in all mainland
states in Australia.; most common in Central and Eastern Australia, also in
Papua and New Guinea. In a variety of habitats: rocky slopes, plateaux and
outcrops of granite and sandstone in skeletal reddish soils with spinifex; on
plains in red sand or sandy to clayey loams in open Acacia woodlands
especially Mulga; depressions and creeklines on gibber plains with chenopods;
floodplains in red to brown clayey soils in open eucalypt woodland; rocky
slopes and outcrops of granite in pockets of sandy loam in eucalypt forest or Callitris
and eucalypt woodland with a grassy understorey.; flowers and fruits throughout
the year.
