Morphology General Habit
Tufted perennial with slender rhizomes.
Morphology Culms
Culms 25–90 cm. high, erect, clad below in papery leaf-sheaths which form a soft spongy covering, rarely the sheaths tight and the culms wiry and ascending.
Morphology Leaves
Leaf-blades rather short and broad, mostly 8–25 cm. long and 4–10 mm. broad, sometimes narrow and linear, rarely involute, pubescent above and below, rarely glabrous, abruptly narrowed or obtuse at the tip; ligules papery, ± 5 mm. long.
Morphology Reproductive morphology Inflorescences
Panicle untidily cylindrical, 5–15 cm. long and 1–1.5 cm. wide, straw-coloured tinged with violet.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets lanceolate, the awns scarcely protruding; glumes glabrous or obscurely scaberulous, sometimes with a few stiff cilia on the keel; lower glume narrowly ovate, 4–5 mm. long, 1-nerved, acuminate; upper glume lanceolate-oblong, 7–9 mm. long, 3-nerved, the nerves close together, mucronate; sterile lemmas 3.5–5 mm. long, obtusely bilobed, the awn of the upper 5–8 mm. long; fertile lemma 2.5 mm. long, sessile, rarely mucronate; anthers 2–4.5 mm. long.
Figures

Fertile
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 7-9 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume

Lower glume primary vein smooth, or scabrous. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume elliptic; 7-9 mm long; 3-4 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 3 -veined. Upper glume primary vein smooth, or scabrous. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets dissimilar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret oblong; 3.5-5 mm long; 1.5-2 length of fertile lemma; membranous; without keels; 5 -veined; pilose; lobed; 2 -fid; obtuse; awned. Awn of lower sterile floret dorsal; arising 0.6 way up back of lemma; 1-3 mm long. Lemma of upper sterile floret oblong; 3.5-5 mm long; 1 length of lower sterile floret; membranous; pilose; lobed; 2 -fid; obtuse; awned. Awn of upper sterile floret dorsal; arising 0.33 way up back of lemma; geniculate; 5-8 mm long. Fertile lemma orbicular; 2.5 mm long; cartilaginous; shiny; without keel; 5 -veined. Lemma lateral veins obscure. Lemma margins convolute; covering most of palea. Lemma apex obtuse. Palea oblong; 1 length of lemma; 1 -veined; without keels.
