--><span class="statement" id="st-undefined" data-properties=""><b>Culms </b>trigonous in cross section, 40–120 cm; vegetative culms hard, solid with parenchyma, taller than fertile culms. <b>Leaves</b>: basal sheaths reddish purple, inner bands fibrillose with age; sheaths with apex of inner band strongly reddish purple tinged, thickened, especially on distal sheaths, thickened portion opaque, smooth, glossy, essentially veinless at apex, not ladder-fibrillose, glabrous; ligules 3–12.5 mm; blades 2.5–8.8 mm wide, glabrous, not papillose abaxially. <b>Inflorescences</b> 13–50(–60) cm; spikes erect or ascending; proximal 2–4(–6) spikes pistillate; terminal 1–8 spikes staminate (rarely gynaecandrous). <b>Pistillate</b> scales lanceolate to narrowly ovate, apex acute to acuminate, scabrous-awned, glabrous. <b>Staminate</b> scales lanceolate to narrowly ovate, apex obtuse to acuminate, occasionally scabrous-awned, glabrous. <b>Perigynia</b> 12–22-veined, (5.3–)6–11.5 × (1.7–)2.1–3.9 mm, sparsely to densely pubescent (very rarely glabrous); beak 2.1–4.4 mm, pubescent, teeth straight to spreading, (1–)1.2–2.3(–2.8) mm.</span><!--

|discussion=<p><i>Carex trichocarpa</i> is quite uncommon in large portions of its range (E. L. Core 1968).</p><!--
--><p><i>Carex trichocarpa</i> rarely hybridizes with <i>C. atherodes</i>, <i>C. lacustris</i> (P. M. Catling et al. 1989), and <i>C. pellita</i> (C. ×caesariensis Mackenzie, according to A. A. Reznicek and P. M. Catling 1985). Hybrids of <i>C. trichocarpa</i> with <i>C. laeviconica</i> are uncommon in the zone of overlap of these two species (D. Castaner and A. A. Reznicek 1988); one collection of that hybrid is known from Nebraska, although <i>C. trichocarpa</i> has not yet been recorded from the state (S. Rolfsmeier and B. Wilson 1997). A single collection with glabrous perigynia has been seen.</p>
