Scientific name: Prostanthera palustris

Common name: Swamp Mint-bush

Prostanthera sp. Bundjalung Nat. Pk. (B.J.Conn 3471) is now known as P. palustris (CHAH 2010). Previously, the species P. sp. Mt Tinbeerwah (C.Sandercoe C1256) was considered synonymous with P. palustris (Conn 2000 pers. comm.); this taxon is now considered to be a separate species (CHAH 2010).

Swamp Mint-bush is a low, straggling, herb-like shrub with a few slender branches up to 90 cm long. It winds inconspicuously through other vegetation. Unlike many other mintbushes, it has little or no aromatic smell. The leaves are less than 1 cm in length, spoon-shaped, mid-green above and paler below. The small, lobed flowers are pale mauve with a yellow-dotted white throat (NSW DECCW 2005ke).

Swamp Mint-bush is known from the Jerusalem Creek area of the Bundjalung National Park near Evans Head, New South Wales (Conn 1997). Locations include Black Rocks, Serendipity Road and Hell Hole Fire Trail (Quinn et al. 1995).

A population estimate for Swamp Mint-bush is unavailable, but the population along Hell Hole Fire Trail is described as growing along a drainage channel and consists of 50 plants (Harden 1992; Quinn et al. 1995).

Swamp Mint-bush is described as growing in coastal wet shrubland/heathland in alluvial sandy soils subject to prolonged waterlogging (Conn 1997; Quinn et al. 1995). The soil is a white siliceous sand with a high organic content (Conn 1997). Associated plant species include Coast Banksia (Banksia integrifolia), Golden Banksia (B. ericifolia), Black Sheoak (Allocasuarina littoralis), Hibbertia serpyllifolia, Schoenus brevifoliusHibbertia salicifolia and Wallum Boronia (Boronia falcifolia) (Conn 1997).  

Associated species at the Hell Hole Fire Trail population include Swamp Mahogany (Eucalyptus robusta), Smudgee (Angophora woodsiana), Dwarf Banksia (Banksia oblongifolia), Ptilanthelium deustum, Swamp Grass-tree (Xanthorrhoea fulva), Common Aotus (Aotus ericoides) and Hibbertia vestita (Sheringham n.d. pers. comm. cited in Quinn et al. 1995).

The Swamp Mint-bush flowers from February to June (Conn 1997). Fruiting has only been recorded in February (Conn 1997). It has been reported that a high intensity fire had killed the banksia wet heath where the species grows and that all individuals were resprouting from basal stem buds (Sheringham n.d. pers. comm. cited in Quinn et al. 1995).

The following threats to the Swamp Mint Bush have been reported (NSW DECCW 2005ke):

  • too frequent fire
  • damage to plants during track maintenance
  • trampling by visitors to Bundjalung National Park
  • risk of local extinction because populations are small.

The following actions have been reported as appropriate threat abatement measures for the Swamp Mint Bush (NSW DECCW 2005ke):

  • Stay on established tracks when visiting national parks to avoid damaging delicate plants.
  • Protect areas of habitat from frequent fire.
  • Identify plants and protect them during road maintenance works.
  • Protect areas of potential habitat from clearing.
  • Notify the NSW Office of Environment and Heritage of any additional occurrences of Swamp Mint-bush.

Management documents relevant to the Swamp Mint Bush include:

  • Northern Rivers Regional Biodiversity Management Plan (NSW DECCW 2010l).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
