Scientific name: Maundia triglochinoides
Conservation status in NSW: Vulnerable
Commonwealth status: Not listed
Gazetted date: 15 Jun 2001
Profile last updated: 08 Aug 2019


Perennial with rhizomes about 5mm thick and emergent tufts of leaves arising along their length. Leaves are spongy, inflated and triangular in cross section, to 80 cm long, sometimes longer, 5 - 10mm wide. Inflorescence to 10cm long and 2.5 cm wide. Carpels (female parts of flower) 6 - 8mm long, sessile, each with a spreading beak. The fruit is 1cm long to 8mm wide.


Restricted to coastal NSW and extending into southern Queensland. The current southern limit is Wyong; former sites around Sydney are now extinct.

Habitat and ecology

  • Grows in swamps, lagoons, dams, channels, creeks or shallow freshwater 30 - 60 cm deep on heavy clay, low nutrients.
  • Flowering occurs during warmer months.
  • Associated with wetland species e.g. Triglochin procerum.
  • Probably wind pollinated.
  • Diaspore is the seed and root tubers, which are probably dispersed by water.
  • Spreads vegetatively, with tufts of leaves arising along rhizome. Populations expand following flood events and contract to more permanent wetlands in times of low rainfall.
  • Flowers November-January.
