Scarce on rock ledges or stony ground in mountains

Tepals c 2.5-3 mm long.  Bracts at base of inflorescence c 2-8 cm long.

ID: Easy - a single flower or tight cluster of flowers in the angle of 2-3 very long leaf-like bracts.  Whole plant has a Y shape. (young stems of other rushes, eg Toad Rush or Slender Rush, can have this shape, but their inflorescence branches out by the time the flowers open)

Other features: Tufted and with creeping rhizomes.  Stems rigid, base covered with leaf-sheaths, some prolonged into short leaves.  Otherwise no leaves up the stem until the bracts.  Fruit has a long pointed tip.
