It is a creeping stoloniferous perennial herb, up to 50 cm tall; leaves are stiff, narrow, about 10 cm in length, with sheaths ciliate on margin (Clayton 1994). Usually every inflorescence has two racemes 1.5-7 cm, with ovate, pale-green spikelets. The upper glume is appressed and puberulent. It is adapted to marshy, brackish conditions and saline soils, which are moist in summer.
