Global Range: Widespread, but very spotty distribution. Websteria confervoides is known from southern Georgia, Florida, Cuba, Central America (Guatemala, Honduras, Nicaragua), South America, Madagascar, India, and Sri Lanka. In Georgia, it is currently known from Ware County, historically in Seminole County; in Florida, current in Highlands, Leon, Marion, Okaloosa, and Santa Rosa Counties, historical in Alachua, Calhoun, Hernando, Lake, Orange, and Volusia Counties. There is a specimen from Blue Pond, Covington County, Alabama, but it needs verification before being accepted. It is mapped in 12 Louisiana parishes in the 1993 Atlas of Louisiana Vascular Flora, but all specimens were examined and proven to belong to species of Eleocharis (J. Larke pers. comm. 1994). Thus, in the United States, W. confervoides has been reliably vouchered from only 13 counties in 2 states, of which at least 6 counties support current populations.
