Endemic to Western Australia, it occurs on floodplains and along water-courses throughout the arid north-west corner of the State.
The delta is ecologically important and includes a wide variety of habitats, including Mesic flood plains, cypress-gum swamps, tidal brackish water marshes, bottomland forests and submersed grassbeds.
It grows on dunes, floodplains and riverbanks, many of these locales being located near the Columbia River.
