Eleocharis nigrescens (Nees) Steudel. Phen: May-Dec. Hab: Pond margins, pine flatwoods. Dist: Se. NC (historical), SC to FL; West Indies, Mexico; South America; Africa. The native status of this species in the southeastern coastal plain is uncertain. The earliest collection that can be confirmed in FL was not until the 1940's (Ward and Leigh 1975); however, a single collection near Wilmington, NC predated this by more than 70 years (Canby s.n.; October 1867). While often present in disturbed wet ditches and similar habitats, it can also occur in relatively intact wet flatwoods, further complicating our understanding of its historical and current nativity.
