The sedge can form a densely packed turf like arrangement with plants having no obvious rhizomes. It has 20 to 100 cm (7.9 to 39.4 in) long culms that are 2.5 to 8 mm (0.098 to 0.315 in) wide at the base and 0.7 to 1.6 mm (0.028 to 0.063 in) wide at the terminus. The leaves are surrounded by loose sheaths. The 4 to 8 mm (0.16 to 0.31 in) wide leaves have green and white striping at the terminal end with transverse veins on the back. The front side is covered in 2 to 7 mm (0.079 to 0.276 in) long projections. It forms inflorescences that have five to fifteen spikes that are 1 to 5 cm (0.39 to 1.97 in) in length and 8 to 15 mm (0.31 to 0.59 in) wide.[5]
