Xyris gracilis is a tufted herb with flat, linear leaves 60–29 cm (24–11 in) long and 1–4 mm (0.039–0.157 in) wide with a sheathing base 14–60 mm (0.55–2.36 in) long and brown or reddish. There are usually 5 to 8 yellow inflorescences, each 5–8 mm (0.20–0.31 in) on flowering stems 27–66 cm (11–26 in) long, each inflorescence with 6 to 14 bracts arranged in 3 to 5 whorls and the flowers opening one at a time. The style is 5–6 mm (0.20–0.24 in) long with branches 2–4 mm (0.079–0.157 in) long. Flowering occurs in December and January.[2][3][4]

Xyris gracilis was first formally described in 1810 by Robert Brown in Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[5][6] The specific epithet (gracilis) means "slender".[7]
