Eleocharis equisetoides, with common names including Horsetail spike-rush, jointed spike-rush, spikesedge, and knotted spike-rush, is a species native to the United States and Canada, usually in freshwater wetland areas. It is known from every state along the coast from Texas to Maryland, plus Connecticut, Rhode Island, Massachusetts, New York, Ontario, Michigan, Indiana, Wisconsin and California.[3]
Eleocharis equisetoides and the related E. interstincta have hollow stems with complete transverse septa. This gives them a jointed appearance superficially resembling the stems of some species of Equisetum. The two species can be distinguished by the length of the perianth bristles subtending the achenes.[3][4][5]
