Small tufted herb, with narrow leaves gradually tapering to a fine apex. Leaves 2-5 cm long, 1-1.5 mm wide, partially transparent. Flowerheads spherical, 3-4 mm diameter on ribbed leafless stalks. Heads have central male flowers and surrounding female flowers, all enclosed by layers of bracts. The fruit is a smooth 3-celled capsule, with 1 seed per cell.


Known in NSW from widely separated populations: a very early “Murray River” collection and recent collections near Braidwood and in the Pilliga. The species is known from three sites in Victoria, one of which just extends into South Australia.

Habitat and ecology

  • Habitats in Victoria are generally aquatic with shallow water, including swamps and sedgelands.
  • Flowers in summer.
  • Recorded as uncommon in populations.
