Paspalum quadrifarium Lam.
Family Poaceae
Common name: Tussock Paspalum

Paspalum quadrifarium Lam. APNI*

Description: Rather large, coarse, caespitose perennials to c. 1.8 m tall, without rhizomes or these very short and contracted.

Sheaths mostly glabrous except with long hairs near the ligule; ligule firmly scarious, thin and dry obtuse, 1–3 mm long, with a rather dense row of long hairs behind it; blade 5–8 mm wide.

Inflorescence 12–25 cm long, roughly linear-lanceolate in outline with usually 15–25(-40) rust-coloured racemes along an elongate common axis, the longer basal ones c. 6–9 cm long and erectly spreading, the upper progressively shorter and more appressed, bearing spikelets in 4 irregular ranks. Spikelets ovate-elliptical to ovate-lanceolate, c. 2.5 mm long, ferruginous or crimson, obtuse. Lower glume absent. Upper glume membranous, pubescent with short whitish hairs erect from minute brownish papillae, 3-nerved, convex, as long as the spikelet; lower lemma very similar to the upper glume but flat, and glabrous with a few similar hairs. Fertile lemma thinly crustaceous, pale, equalling the upper glume and lower lemma, widely elliptical, obtuse, convex, subsmooth, subshining, very faintly nerved; palea similar to the upper lemma in texture, flat.
