Tufted perennial 450-850 mm high; leaves mainly basal; lowest node of old culms clothed in leaf sheaths. Leaf blade 300-500 x to 2 mm, usually setaceous, rarely wider, parallel-sided at base; ligule an unfringed membrane, 5-12 mm long, papery, pointed. Inflorescence narrow, lowest raceme base not fused and swollen; internode and pedicel hairy along margins, back glabrous. Sessile spikelet 5-6 mm long; lower glume less than 6.5 mm long, nerveless or 2-nerved, broadly winged, flat, shallowly concave at base; awn 11 mm long. Pedicellate spikelet 5.0-6.0 mm long, lower glume narrowly winged in upper part.
Perennial, up to 0.85 m tall; fresh shoots aromatic. Leaves linear, up to 2 mm wide; ligule an unfringed membrane up to 12 mm long. Inflorescence a complex leafy panicle, racemes paired, short, (10-)15-20(-28) mm long, and often reflexed, rhachis and pedicels with long hairs on margins only; spikelets paired in a sessile and pedicellate combination of dissimilar spikelets. Sessile spikelet 5-6 mm long, lower glume winged; lemma awn 11 mm long, glabrous.
