Ecology and Geography

Plant typeangiosperm
Floristic region(s)East Pacific Islands , Maritime Southeast Asia , Australia (tropical)
Habit aquatic(s)floating attached, submerged
Habitat notesShallow water on edge of swamp. Potamogeton species are found throughout the world where there is standing or running water. There are estimated to be around 90 species but hybridisation provides an added complexity to the taxonomy. Commonly called pondweed (note that not all pondweeds are Potamogetons), is a genus of aquatic, mostly freshwater. In many species, all the leaves are submerged, typically thin and translucent. Some species, especially in ponds and very slow moving waters, have floating leaves which tend to be more leathery. Seeds found in the KAO3 macrofossils for Rano Kao, Rapa Nui (Easter Island) but pollen not identified in fossil record,perhaps lost in processing.
