leaden spikelets with numerous closely imbricate florets and straight rachilla;
slender flaccid panicle; plant mostly glabrous and smooth, highly coloured,

distribution is from northern and central Australia from around the Dampier
Penin. and Port Hedland in W.A. across to about Mackay on the E coast of Qld. S
to Wee Waa in northern N.S.W. Commonly in seasonally wet habitats (beds,
frontages and levees of watercourses, floodouts, seepage slopes, margins of
swamps and springs) with sandy alluvial soils; also in lateritic, calcareous
and saline soils and moist disturbed ground.; flowers all year round but not recorded
