Locally common in peat bogs.

Individual spikelets (normally 2-flowered) c 4-5 mm vertically

ID: Appearance unique when white or cream-coloured.  Turns pale brown later on but still very distinctive, with inflorescence about as broad as long, flattened vertically, with bract averaging slightly longer than inflorescence.  Do not confuse mature specimens with the rare Brown Beak Sedge, which has dark brown spikelets and bracts over twice as long as inflorescence.

Other features: Leaves grooved, often with bulbils at base.  Lowest sheaths leafless, also often with bulbils.  Fruit is a beaked nut surrounded by about 9-13 bristles which are no longer than the nut.
