Scientific name: Maundia triglochinoides
Gazetted date:
15 Jun 2001
Profile last updated:
08 Aug 2019
Description
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.
Distribution
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.

Threats
- Clearing and habitat degradation from urban, rural, agricultural, and forestry development and activities.
- Altered hydrology with both increased and decreased periods of inundation and changes of salinity, impacts the security of this wetland species.
- Weed invasion by aquatic and semi aquatic weeds including Eichhornia crassipes, Ludwigia longifolia, Salvinia molesta, and Cabomba caroliniana.
- Inappropriate fire regimes including both low frequency fire and too frequent fire.
- Grazing and trampling by domestic stock.
- Overgrazing, trampling and disturbance to the species and its habitat by feral animals including pigs and deer.
- Pollution including herbicide, pesticides, fertilisers, and sedimentation from runoff.
- Climate change causing sea level rise leading to changes in flooding regimes and loss of habitat.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Implement habitat management programs to address threats at sites.
- Protect habitat from further clearing.
