--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual, tufted, often mat-forming, often stoloniferous, sometimes entirely vegetative; rhizomes absent. <b>Culms</b> erect, ascending or arching, quadrangular, sulcate, 1–13 cm × 0.1–0.3 mm, soft. <b>Leaves</b>: distal leaf sheaths persistent or disintegrating, red-brown, stramineous, green, or mottled red-brown, translucent, apex narrowly acute. <b>Spikelets</b>: basal spikelets often present, bisexual; often proliferous, ovoid or ellipsoid, laterally compressed when young, but terete at maturity, 2–7 × 1–2.6 mm, acute; proximal scale empty, often persistent, amplexicaulous, similar to floral scales; subproximal scale with a flower; floral scales spirodistichous (superficially appearing ± spiraled), (4–)10–28, 6–9 per mm of rachilla, pale brown, mottled red-brown to purple, ovate or elliptic, 1.3–2.1 × 0.7–1 mm, membranous, midribs green and red-brown, prominent, apex rounded to obtuse. <b>Flowers</b>: perianth bristles 6, colorless, white, or stramineous, slightly shorter than to equaling achene, spinules retrorse, acute; stamens 3; anthers 0.4–0.5 mm; styles 3-fid. <b>Achenes</b> greenish or pale brown or red-brown, often clearly spotted greenish or red-brown, ellipsoid to obovoid, trigonous (or terete?), angles prominent (keeled), 0.6–0.8 × 0.4–0.5 mm, apex constricted proximal to tubercle, smooth. <b>Tubercles</b> red-brown, pyramidal, trigonous, 0.1–0.3 × 0.2–0.4 mm.</span><!--

|discussion=<p><i>Eleocharis minima</i> is most often confused with <i>E. bicolor</i> and <i>E. baldwinii</i> (see comments under 33. <i>E. bicolor</i>). Although floral scales in <i>E. minima</i> often superficially appear to be spirally disposed, in reality they are spirodistichous, ± decussate, while in <i>E. baldwinii</i> they are strictly distichous in one plane. The number of floral scales per millimeter is much greater in <i>E. minima</i> than in <i>E. baldwinii</i>.</p>
