Description

Sand Spurge is a herb that forms mats to 1 m across. It grows on dunes and sea strandlines. Leaves are smooth, to 30 mm long and 15 mm wide. The tiny flower-heads are surrounded by white leaf-like processes (bracts); each flower-head actually comprises a female flower surrounded by up to five sprays of minute male flowers, hidden in a cup from which the bracts grow. The fruiting capsule is smooth and about 2 mm long.

Distribution

Sand Spurge is found sparsely along the coast from south of Jervis Bay (at Currarong, Culburra and Seven Mile Beach National Park) to Queensland (and Lord Howe Island). Populations have been recorded in Wamberal Lagoon Nature Reserve, Myall Lakes National Park, Moonee Beach Nature Reserve and Bundjalung National Park.

Habitat and ecology

  • Grows on fore-dunes, pebbly strandlines and exposed headlands, often with Spinifex (Spinifex sericeus) and Prickly Couch (Zoysia macrantha)
  • Flowering recorded in spring and summer.
  • Sand Spurge seeds float, so some dispersal between beaches may occur.
  • Longevity of the species is approximately 5 – 30 years with a primary juvenile period of less than 1 year.
  • Plant growth occurs in spring and summer.
