Perennial, densely tufted, 0.65 m high, wiry. Leaf blades 50-250 mm long, setaceous or up to 3 mm wide. Culms unbranched, bases erect, clad in hard, shiny, yellowish sheaths. Spikelets 5.5-7.0 mm long. Panicle contracted, rarely open, branched; glume tips reddish brown, often shining; lemma awns hair-fringed; anthers 2.5 mm long.
Spikelets 5.5-7 mm. long, 3-flowered, less crowded than in the other spp. Glumes slightly unequal, with the apices usually bright orange, brown or rubiginous; the inferior 4-6 mm. long, 7-9-nerved; the superior 4.4-6.6 mm. long, 5-nerved.
Panicle up to 15 cm. long, ovate-oblong to oblong in outline, loose and somewhat open, rarely dense but never spike-like; branches up to 5 cm. long, obliquely ascending to erect, often appressed to the rhachis.
Fertile lemma (the inferior) 2.5-3 mm. long (excluding the awns), dorsally villous; awns 2-4.25 mm. long, plumose beyond the middle towards the apices, often tinged with orange or brown.
Leaf-laminae 5-25 x 0.2-0.4 cm., usually with the margins involute, rarely expanded (sometimes towards the base only), tapering to a fine pungent point, somewhat rigid.
Culms 30-75 cm. tall, 2-5-noded, slender but less wiry than in the preceding sp., simple (!), erect or sometimes ascending from a shortly geniculate base.
A caespitose perennial, with a short oblique or almost vertical rhizome, very inconspicuously pubescent to almost glabrous.
Leaf-sheaths tight at first, later somewhat loose but always firm, the lowermost long-persistent, pale.
Anthers 2.3-2.7 mm. long.
