Did you know?
The species name fallax is Latin for deceitful or deceptive and its common name in some states is deceitful spike-rush. This refers to its close relationship to other similar species and the difficulty of telling them apart (Flora of North America Editorial Committee 2002). Another of its common names, creeping spike-rush, is also used for the more common Eleocharis palustris.

State Ranking Justification [-]
