--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, cespitose, to 100 cm; rhizomes absent. <b>Culms</b> erect to ascending, arching, lax, leafy, slender, trigonous. <b>Leaves</b> exceeded by inflorescence; blades ascending to spreading, linear, proximally flat, 1–2(–3) mm wide, apex trigonous, subulate, tapering. <b>Inflorescences</b>: spikelet clusters 4–6, mostly dense, widely spaced, narrowly turbinate to ellipsoid; peduncles erect to ascending, branches ascending; leafy bracts exceeding proximal clusters. <b>Spikelets</b> dark brown, ovoid, 2–3 mm, apex acute; fertile scales broadly ovate to ± orbiculate, cupulate, 1.5–2 mm, apex rounded to acute, midrib included or excurrent as bristle. <b>Flowers</b>: perianth bristles 6, from vestigial to (rarely) reaching tubercle tip, antrorsely barbellate. <b>Fruits</b> 2–3 per spikelet, 1.2–1.5 mm; body brown, obovoid to globose, lenticular, 1–1.2 × 0.8–1 mm, margins narrow, distinct; surfaces sharply transversely wavyrugose, intervals with rows of vertical, broadly rectangular or ± isodiametric alveolae; tubercle lowtriangular or triangular, compressed, 0.2–0.3 mm, base lunate.</span><!--

|discussion=<p>Through much of the range of <i>Rhynchospora microcarpa</i>, particularly in limesink or claybased pond areas, is a somewhat shorter series of plants with narrow leaves, tumid fruit 0.7–0.9 mm, often with isodiametric alveolae and depressedtriangular tubercles. Described by S. Gale as R. sulcata, the plants grade into the more typical morphology for <i>R. microcarpa</i>. In peninsular Florida, apparent intergradation with <i>R. elliottii</i> produces some individuals with broad leaves and triangularsubulate tubercles on nearly flat fruits.</p>
