Fairly frequent in bare mud.

A short plant, usually < 15 cm high.  Spikelets 3-5 mm long.

ID: Spikelets usually 2-3 together, their bract appearing as a continuation of the stem that goes well beyond the spikelets.  Fruit ribbed - this is necessary to distinguish it from the rare I cernua, which has non-ribbed fruit, but that species usually also has the bract no longer than the spikelets, and has paler glumes than I setacea.

Other features: Tufted, often an annual.  Leaves thread-like, channelled, single or paired, from base of stem and shorter than stem.
