--><p><i>Eleocharis ravenelii</i> is apparently very uncommon in North America. It is often mistaken for very slender-stemmed <i>E. montana</i>, which differs in its spikelets with floral scales 1.5 mm or more, 100–500 per spikelet and 15–40 per mm of rachilla, its mostly larger and biconvex achenes, and its culm septa usually evident without sectioning the culm. Although the holotype of <i>E. ravenelii</i> (NY), from Corpus Christi, Texas, lacks culm bases and leaf sheaths, its culms, spikelets, floral scales, and achenes are typical of the later <i>E. austrotexana</i> M. C. Johnston.</p>
