Common in wet ground including ditches and edges of burns

Tepals c 3 mm long

ID: Leaves have horizontal lines at intervals in common with Sharp-flowered Rush (see pic there).  Distinguished from Sharp-flowered Rush by dark brown tepals and by branches being nearer vertical than horizontal.

Other features: Very variable in uprightness and robustness.  Leaves are generally more flattened than Sharp-flowered Rush but there is some overlap.  Hybridises with Sharp-flowered Rush, and many intermediate specimens are very difficult to identify, but short curvy plants with a blackish-brown rather than greenish-brown look to the inflorescence are Jointed Rush.  The ripe fruit protrudes well beyond the tepals, while in the hybrid it hardly protrudes at all.
