Description

Waterwheel Plant is a member of the sundew family. It is a water-plant that traps and digests aquatic insects. Its leaves face outwards from the stem and snap shut on small water animals that trigger the long, sensitive hairs surrounding each leaf. The plant floats below the water's surface, and can be seen caught on underwater vegetation. It has stems 5 - 20 cm long, with whorls of 5 - 9 reddish-coloured leaves. The small, white or pinkish flowers emerge from the water, but the fruit capsules are held underwater.

Distribution

The species is more commonly found in northern Australia and tropical regions of Asia and Africa. Known in NSW only from lagoons in the Moruya area on the south coast, from the Evans Head area on the north coast and from north of Guyra on the New England Tablelands.

Habitat and ecology

  • Found free-floating in near-coastal shallow freshwater lagoons that are rich in organic matter.
