--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, cespitose, 80–150(–170) cm, coarse; rhizomes absent. <b>Culms</b> stiffly erect, leafy, triangular, multiribbed. <b>Leaves</b> ascending, overtopped by inflorescence; blades flat proximally, 3–10(–15) mm wide, apex attenuate, trigonous. <b>Inflorescences</b> terminal and axillary, narrow, clusters of corymbs, clusters dense, mostly broadly turbinate, 13–15 mm; bracteal leaves mostly exceeding subtended compounds. <b>Spikelets</b> brown, lanceoloid, 13–15 mm, apex acuminate; fertile scales lanceolate, 10–13 mm, apex acuminate, midrib shortexcurrent. <b>Flowers</b>: longer perianth bristles usually fully 2 times length of fruit body, antrorsely barbellate. <b>Fruits</b> 1–2 per spikelet, 20–25 mm; body pyriformobovoid, compressed, 5–6 × 2.6–3.6 mm; tubercle attenuate, 2-grooved, (15–)18–20(–21) mm. <b>2n</b> = 18.</span><!--

|discussion=<p><i>Rhynchospora macrostachya</i> is quickly distinguished from other species of its complex by more compact clusters, arranged on successive mid and distal nodes to present a narrow inflorescence outline. Its perianth bristles and fruit tubercles are the longest in the complex, probably in the entire genus.</p>
