The sedge has a woody rhizome with central culms that have a triangular cross-section with a length of 20 to 50 cm (7.9 to 19.7 in) and a width of 1 to 3 mm (0.039 to 0.118 in) and that are smooth lower down with a rough texture toward the top. It has basal flattish to folded lengthwise leaves with a broadly linear to lanceolate shaped blade that is 17 to 60 cm (6.7 to 23.6 in) long with a 1 to 7 cm (0.39 to 2.76 in) long dark brown sheaths that usually disintegrate. The narrow inflorescences appear as a narrow branched cluster with a length of 17 to 20 cm (6.7 to 7.9 in) with three to six crowded to distant nodes.[2]
