--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, cespitose, 60–80 cm; rhizomes absent. <b>Culms</b> erect or ascending, leafy, trigonous, slender. <b>Leaves</b> all exceeded by culm; basal blades spreading, often curled, distal longer, all proximally flat, 3–5 mm wide, apex trigonous, subulately tapering. <b>Inflorescences</b>: clusters 3–5, proximalmost distant, longest pedunculate, fascicles broadly turbinate to hemispheric; leafy bracts of distal groups mostly exceeded by inflorescence. <b>Spikelets</b> lanceovoid, (3.5–)4–5 mm; fertile scales broadly ovate to ± orbiculate, cupulate, rounded, 3 mm, apex apiculate to cuspidate, midrib excurrent. <b>Flowers</b>: perianth bristles 6, overtopping tubercle (or at least its base), antrorsely barbellate. <b>Fruits</b> 1–3 per spikelet, 2.3–3 mm; body brown, strongly compressed proximally, biconvex distally, broadly obovoid, 1.8–2.2 × 1.5 mm; surfaces strongly transversely rugose, intervals with rows of narrow, vertical alveolae; tubercle triangular, flat, 1 mm, base lunate, capping fruit apex, apiculate.</span><!--

--><p><i>Rhynchospora punctata</i> is similar to <i>R. harveyi</i> and <i>R. compressa</i> in its preference for more upland sites. Like <i>R. compressa</i>, <i>R. punctata</i> often has many imperfectly formed fruits, suggestive of hybrid origin.</p>
