--><span class="statement" id="st-undefined" data-properties=""><b>Rhizomes </b>1–4 mm diam., tough, hard. <b>Culms</b> ridged, 10–70 cm × 0.5–2 mm, hard, without evident internal air cavities. <b>Leaves</b> 5–10; sheaths loose, the proximal often disintegrating to prominent fibers, often stramineous or brownish, papery, fronts membranous-hyaline with delicate veins, summit slightly concave with V-shaped veinless area and often disintegrating; blades 0.5–1 times as long as culms, hard, without evident internal air cavities; distal blades 3–30 cm × 0.5–2 mm, longer than sheaths, margins sparsely antrorsely spinulose or papillose, apex sharply acute. <b>Inflorescences</b>: proximal involucral bract 1–15 cm, resembling foliage leaf blade. <b>Spikelets</b> ovoid to lanceoloid or terete, 5–20 × 3–5 mm; scales pale to dark red-brown, midribs usually stramineous, smooth; proximal 1 or 2 scales often resembling involucral bracts, with awnlike blades, to 15 mm; other scales in proximal part of spikelet prominently 9-veined, ovate, 4 × 3 mm, papery to often cartilaginous, margins hyaline, ciliolate, apex entire, acute to rounded. <b>Flowers</b>: perianth bristles pale brown, unequal. <b>Achenes</b> greenish to orange-brown, broadly obovoid, 2–2.3 × 1.5–1.7 mm.</span><!--

|discussion=<p><i>Amphiscirpus nevadensis</i> superficially resembles some dwarfed forms of <i>Schoenoplectus pungens</i>, with which it sometimes grows; <i>S. pungens</i> is readily distinguished by its trigonous culms and leaf blades, prominently 2-fid, awned scales, and beaked achenes. <i>Amphiscirpus nevadensis</i> differs from all North American species of <i>Schoenoplectus</i> in its wiry culms and leaves, prominently ciliate ligules, absence of evident internal aerenchyma, and beakless achenes. It has been reported from Delta, Manitoba.</p>
