|discussion=<p><i>Scleria lacustris</i> is adventive in Florida and was first collected in 1988. It has since been found in additional sites and is becoming locally common (C. C. Jacono 2001). The plant is a coarse sprawling annual that appears to have the potential to be a serious invasive in warmer parts of Florida.</p>
