Gahnia lanigera, commonly known as the black grass saw-sedge, desert saw-sedge, or little saw-sedge, is a flowering plant in the sedge family native to southern Australia. The specific epithet lanigera means “woolly.” This plant is a rhizomatous, tufted perennial that can grow up to 45 cm tall and 2 m wide, with stiff, narrow, sharp-pointed leaves.
