Profile last updated: 17 Aug 2018


Round-leafed Wilsonia is a prostrate, perennial plant with succulent leaves. Its leaves are rounded and shiny, to 7 mm long and 3 mm wide, and more or less stalkless. The leaves are arranged in neat rows along the spreading stems. When young the leaves are hairy. The five-lobed 5 mm long, white, cream or yellow, tubular flowers occur singly in the angle between the leaf and the stem (axil). The fruit is an oval capsule containing one black seed.


Round-leafed Wilsonia is known from several sites in the Jervis Bay area, Royal National Park, near Deniliquin and on the lakebeds of Lake George and Lake Bathurst when these are exposed during droughts. The Lake George and Lake Bathurst populations appear to be locally extensive. Also found Western Australia, South Australia and Victoria.

Habitat and ecology

  • Grows in mud in coastal saltmarsh and inland saline or brackish lake beds.
  • In undisturbed habitat, it can be a good coloniser as the creeping stems root from the nodes.
  • Flowers appear mainly in spring and summer.
  • May be a clonal species so that what appear to be large populations at some sites may actually be composed of only limited numbers of genetically distinct individuals which are the result of vegetative (asexual) reproduction.
