It is perennial sedge 60-120 cm tall with a shortened rootstalk. The bright green leaves are 10-15 mm broad. The flower spikes are 5-8 cm long and 1-1.5 cm thick, densely seated on short peduncles below the staminate. Follicles, abruptly narrowed, are perpendicular to the spike stem – and that is the difference from the bladder sedge. It is mainly common in non-chernozem belt: on shorelines, in low moors and swamped meadows. It flowers in May-June.
