Description Tubers terminating rhizomes, 2.5–4 × 0.7–1.5 mm, body (apart from apical bud) broadly oblong to orbicular, not markedly curved. Spikelets 3–6 × 1–1.5 mm; proximal scale 1/2 or less of spikelet length; floral scales 6–25 per spikelet, mostly bright orange-brown, sometimes stramineous, 1.7–2.5 mm, apex subacute. Flowers: perianth bristles mostly absent or rudimentary, occasionally to 5, 1/2 of achene length, very unequal; anthers 0.6–0.9 mm. Achenes medium to dark brown, obovoid to obpyriform, thickly trigonous, rarely some biconvex, angles distinct to prominent, faces convex or some plane, 0.75–1.1 × 0.55–0.7 mm, apex narrowly truncate or tapered into tubercle, rugulose at 10X to finely rough at 30X. Tubercles 0.05–0.2 × 0.15 mm. [details]
