Paspalidium aversum

Tufted perennial. Culms ascending or erect, to c. 90 cm high. Leaves glabrous; blade flat or nearly so, smooth to slightly scabrous, to 25 cm long, 3–9 mm wide; ligule c. 1 mm long. Panicle 8–30 cm long; branches mostly 1–5 cm long, remaining appressed to the glabrous main axis, uppermost spikelets of panicle arising singly from the axis. Spikelets c. 2.5 mm long; lower glume very broadly ovate to circular, c. 1.2 mm long, 3(5)-nerved, the nerves not distinctly connected toward the apex; upper glume broadly ovate, 5-nerved, slightly shorter than the spikelet; lower lemma 5-nerved, as long as the spikelet, its palea membranous, up to c. half as long as lemma, or lacking; upper lemma ovate, as long as or subequal to the spikelet, acute, hardened, finely transversely ridged for all but the apical part, margins pale, of similar texture to the body of the lemma, recurved, concealing less than half the palea width; palea subequal to lemma, hardened, minutely and irregularly transversely ridged.
