--><p><i>Eleocharis reverchonii</i> perhaps should be treated as a variety or subspecies of <i>E. acicularis</i>. One collection (three sheets at KSC) from Calhoun county in southeastern Texas is apparently the only known example within <i>E. </i>subg.<i> Scirpidium</i> with proliferous spikelets.</p>
