Eleocharis vivipara Link. Viviparous Spikerush. Phen: Jul-Sep. Hab: Coastal Plain ponds, small depression ponds, semipermanent impoundment ponds, beaver ponds. Dist: NC south to FL, west to TX. Apparently disjunct in Cherokee (Whetstone 15348, JSU) and Jackson (K.R. Brodeur 2123, JSU) counties, Alabama. The latter specimen contains ovoid spikelets with spiraled scales, which matches this species; however, I have not seen achenes to confirm if the surfaces are honeycomb-reticulate (Ward, personal observation). Otherwise, this species occurs almost exclusively in the southeastern coastal plain, particularly in coastal plain ponds. The disjunct inland records should be investigated further.
