Description Plants perennial, solitary or cespitose, 50–70 cm; rhizomes absent. Culms erect to excurved, leafybased, narrowly linear, ± te-rete. Leaves shorter than culm; blades ascending, narrowly linear, proximally flat or margins slightly involute, 0.5–1(–2) mm wide, distally canaliculate, apex trigonous, tapering, subulate. Inflorescences: spikelet clusters 1–3, laterals 0–2, all turbinate to hemispheric, terminal internode usually excurved; leafy bracts setaceous, overtopping inflorescence. Spikelets redbrown, lanceoloid, 5–7 mm, apex acute; fertile scales lanceolate, (2.5–)4–5 mm, apex acute to acuminate; midrib paralleled by several indistinct ribs, excurrent as short awns. Flowers: bristles 6, reaching from mid tubercle to beyond tip. Fruits 3(–4) per spikelet, 2.1–2.5 mm; stipe and receptacle 0.2–0.3 mm, sparsely setose and setulose; body glossy, brown with pale center, obovoid-lenticular, 1.1–1.5 × 1–1.1 mm, surfaces finely longitudinally lined, variably low papillatecancellate, also often transversely with wavy lines of dark dots; tubercle flattened, triangular-subulate, (0.8–)0.9–1(–1.1) mm, setulose-ciliate. [details]
