 The culms of Carex binervis are 15 – 150 centimetres (6 in – 4 ft 11 in) tall, although typically less than 120 cm (3 ft 11 in). They are triangular in section with rounded corners and often a single furrow. The leaves are 7 – 30 cm (2.8 – 11.8 in) long and 2 – 6 millimetres (0.08 – 0.24 in) wide, light green and shiny on the underside, but dark green and matt on the upper surface. The leaves are flat or slightly keeled, and taper abruptly to a fine point.
