Status: Native
Description:
Densely caespitose perennial; culms up to 250 cm high, erect, glabrous or sometimes villous for a short distance below the nodes. Leaf sheaths usually sparsely pilose, sometimes densely villous, rarely glabrous, the basal nearly always tomentose with pale brown hairs below; leaf laminas up to 60 cm × 4 mm, rigid, scabrid along the margins, usually pubescent below. False panicle 20–60 cm long, narrow, dense; spatheoles 2–3 cm long, narrowly lanceolate, usually appressed-hirsute but sometimes only along the margins; peduncles a little shorter than the spatheoles, copiously barbate all round above with stiff bulbous-based yellow hairs; racemes 0.5–1.5 cm long, 2–4-awned per pair, dark purple, laterally exserted and deflexed; raceme-bases slightly unequal, the superior 1.5–2 mm long, flattened or subterete, barbate with stiff yellow hairs, produced at the apex into a narrowly oblong, purple, irregularly bifid or lobed appendage 1–2.5 mm long, this glabrous, pubescent or even villous. Homogamous spikelets 4–7 mm long, a single pair at the base of the inferior raceme only, glabrous with scabrid margins, awnless. Sessile spikelets 4–6 mm long; callus c. 1 mm long, acute; inferior glume narrowly linear-oblong, coriaceous, glabrous or rarely hirsute, the midnerve raised between two fine longitudinal grooves; awn 1–2.5 cm long, the column shortly pubescent with white hairs. Pedicelled spikelets 4–6(7) mm long, glabrous, muticous or with a short mucro seldom over 1 mm long; callus scarcely developed; pedicel-tooth obtusely triangular, very obscure.
