--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, cespitose, 70–100(–150) cm; rhizomes absent. <b>Culms</b> erect to ascending, leafiest at base, triangular, slender, somewhat stiff. <b>Leaves</b> exceeded by culm; basal blades crowded, spreadingexcurved, distal ascending, linear, proximally flat, 3–5 mm wide, apex trigonous, shortsubulate. <b>Inflorescences</b>: spikelet clusters 3–5, compact, the proximalmost widely spaced, turbinate or lobed to hemispheric; leafy bracts setaceous, mostly overtopping clusters. <b>Spikelets</b> redbrown, broadly ovoid, 3–3.5(–4) mm, apex acuminate; fertile scales broadly ovate to ± orbiculate, 2–2.5(–3) mm, apex rounded to notched, midrib included or shortexcurrent. <b>Flowers</b>: perianth bristles 6, reaching from fruit midbody to tubercle, antrorsely barbellate. <b>Fruits</b> 1–2 per spikelet, (2–)2.5–2.8(–3) mm; body brownish, broadly obovoid to nearly orbicular, 1.5–2 × 1.5–2 mm; surfaces strongly transversely wavyrugose, intervals rows of vertical, rectangular alveolae; tubercle conic-subulate, basal rim flaring above short neck on achene.</span><!--

|discussion=<p><i>Rhynchospora compressa</i> is very closely akin to <i>R. recognita</i> and even coarser; inflorescence clusters are about as bristly and fertile scales blunter than those in <i>R. recognita</i>. It is less inclined to have an excurrent midrib, and the fruit is flatter. Both species often produce sterile spikelets, sometimes comprising an entire inflorescence.</p>
