Very common on moorland, grassland and damp croftland, sometimes forming extensive stands.  Also at edges of lochs.

Stem c 30-90 cm high, c 2-2.5 mm wide.  Tepals c 2-2.5 mm long

Skye ID: Bract of flowerhead looks like continuation of stem, so that flowerhead appears to be emerging from side of stem.  Stem feels smooth, without ridges, though faint lines can be seen.  If ridges present then it's Compact Rush

Other features: Flowerhead varies from loose (var effusus) to dense (var subglomeratus [formerly var compactus]).  There is a third variety (var spiralis) which has tight heads and curly stems spreading out in all directions.  All these occur on Skye.
