The elemental composition of eight aquatic macrophytes from Okefenokee Swamp, Georgia was examined during a comprehensive survey.Nymphaea odorata Ait., Nuphar advenaAit.,Pontederia cordataL.,Lachnanthes caroliniana(Lam) Dandy,Xyris smallianaNash.,Rhynchospora inundata(Oakes) Fern.,Sphagnum cuspidatumvar. serrulata (Schlief.) Schlief., andUtriculariasp. (Utricularia purpureaWalt.,U. junceaVahl. andU. inflataWalt.) were sampled from seven marshes and partitioned into roots, rhizomes, stems, petioles, leaves and flowers. Ash, phosphorus, potassium, calcium, magnesium, sodium, aluminum, iron, and manganese were analyzed with a plasma emission spectrograph. Upper plant parts contained higher concentrations of K, Ca, Mg, Na, and Mn than roots and rhizomes. Iron and aluminum concentrations were highest inUtriculariaand submersed roots. Elemental concentrations were similar to these in aquatic macrophytes found in other regions.
