Picture c 6.2 cm high

Occasional in brackish water or on the shore, becoming rare in the north.

Plant up to c 120 cm tall.  Spikelets c 10-20 mm long.

ID: Egg-shaped spikelets like those of Common Clubrush but larger.  Stems sharply 3-sided, sometimes even winged (stems are round in Common Clubrush).

Other features: Much more leafy than Common Clubrush, with long leaves grooved above and keeled below.  Inflorescence is not always compact and globular as shown in some books, but often has stalked clusters of spikelets.  They have an upright leaf-like bract which appears like a continuation of the stem beyond the infloresence, as well as 2 or 3 smaller bracts at an angle to the stem.
