The sandhill sword-sedge is a tufted perennial with a short vertical rhizome and rigid, erect, sharp-edged culms. It grows to 20–60 cm in height and 3–7 mm in width. The inflorescence is erect, dense, ovate to oblong, 3–15 cm long and 2–4 cm in diameter, with a shorter involucral bract. The numerous spikelets are 5–8 mm long, with 6 to 8 bracts, covered in short fine hairs, red-brown to grey-brown. There are 6 scales at the base of stamen, whitish in colour. The smooth, pale to dark brown, ovoid nut is 2.7–4.0 mm long and 1.3–1.8 mm in diameter. It flowers in spring and summer.[1][2]
