Distinguishing characters include inflated small spikelets similar in length
and width; trigonous caryopsis; persistent glumes; hairy culm internodes;
fragile straight rachilla; minute terminally exserted anthers; relatively wide
palea flaps; long panicles relative to plant; terminal floret in spikelet
vestigial; ovate-orbicular lemmas; ciliate ligule.

 Apparently isolated in its relationships, but
resembling E. exigua in spikelet morphology.

occurs in W.A. near Meekatharra across to S of Warburton in the Great Victoria
Desert, throughout central N.T. and scattered S to L. Torrens in S.A. Also
occurs from Charleville, Qld to S of Louth, N.S.W. Seasonally wet habitats
(swamps, floodplains, dune swales, creek lines, claypans, seepage slopes,
gilgais) in grey, red or brown loams, clay loams and silty clays.; flowers
