--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, cespitose, 10–100 cm; rhizomes absent. <b>Culms</b> erect or excurved, leafy, obscurely trigonous, slender, firm. <b>Leaves</b> shorter than culms; blades spreading to ascending, linear, proximally flat, 2–4 mm wide, apex involute, then trigonous, subulate. <b>Inflorescences</b>: spikelet clusters 1–4, loose to dense, broadly turbinate, lobed or hemispheric; peduncles and branches ascending; leafy bracts exceeding proximal, sometimes distal, clusters. <b>Spikelets</b> light redbrown, ellipsoid or narrowly ovoid, 4–5 mm, apex acute to acuminate; fertile scales broadly ovate, 3.5–4.5 mm, apex acute or acuminate, apiculate. <b>Flowers</b>: perianth bristles mostly 6, reaching from fruit midbody to tubercle tip or beyond, antrorsely barbellate. <b>Fruits</b> 1(–2) per spikelet, 2.5–3 mm; body dark brown, broadly, tumidly obovoid, 2–2.5 × 2–2.5 mm, apically buttressed to tubercle; surfaces finely transversely rugulose or nearly level, with fine transverse rows of pits or low papillae, often appearing nearly smooth; tubercle lowconic, 0.4–0.6 mm, apiculate.</span><!--

|discussion=<p>Of all North American species of Rhynchospora, R. grayi appears best adapted to the xeric conditions found in the coarser sands of the longleaf pine-scrub oak–dominated yellow sandhills. Interestingly, it seems seldom to mix with its closest relative, R. megalocarpa, which is more often found in white sandhills.</p>
