Scientific name: Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781)
Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) is conventionally accepted as a species (CHAH 2010) but is awaiting formal publication. Previously, Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) was considered an affinity of Prostanthera palustris (Conn 2000 pers. comm.), however, this inclusion has been reviewed and is not accepted (CHAH 2010).
Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) is a low, spreading, straggly, herb-like shrub with a few slender branches growing to 1.5 m long. Branches have a band of short, curled and bent hairs between the lateral ridges. Leaves are less than 1 cm long, 4–8 mm wide, spoon-shaped, with few or no hairs, green on the upper surface and pale green on the lower surface. Flowers are small, lobed and pale purple with yellow dots on a white throat (Stanley & Ross 1986).
Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) is known from four sites in the Mt Tinbeerwah area near Tewantin in the southern Wide Bay district, Queensland (Stanley & Ross 1986). The species has a distribution range of approximately 5 km, an extent of occurrence of 7 km² and an area of occupancy is approximately 2 ha. Two of the populations are on freehold land and two are on state forest land (Halford 1998).
The following table shows populations of Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) as outlined by Halford (1998):
|Population size||Area occupied
|Mt Tinbeerwah (Tewantin State Forest)||7 October
|10 000||State Forest||Stand is accessible from the walkway at the carpark to the summit of the mountain. There are no commercial timber values in the vicinity of the population.|
|Lot 1/RP205063 (Illoura Place)||27 October
|21 mature||30||Freehold||Located near the western boundary of the freehold block. A large portion of the block has been cleared in the past but has been allowed to regenerate naturally. Where this species occurs, it appears that the land has only been partially cleared. The freehold property to the west has been heavily grazed.|
|Lot 183/MCH947||27 October
|500–1000 mature||10 000||Freehold||Stand is on the waning lower slope of Mt Tinbeerwah, below the southern cliff face. The population was only estimated visually because the ground layer was very dense.|
|Tewantin State Forest (Sandercoe C1286)||4 October
|unknown||unknown||State Forest||Stand is near Harry Spring Environmental Park.|
|Total||500-1000||at least 20 030|
The total population is estimated to be less than 2000 individuals (Halford 1998).
Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) occurs in shrubland on rocky hillslopes and in tall open forest on gently inclined slopes, or flat terrain on the coastal plain (Halford 1998). Associated species include Red Mahogany (Eucalyptus resinifera), E. racemosa, Pink Bloodwood (Corymbia intermedia), Turpentine (Syncarpia glomulifera), Lophostemon sp., Tall Saw-sedge (Gahnia clarkei) and Black-mouth Bush (Melastoma affine) (Qld DNR 2000).

Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) has been recorded flowering in January, April and November (Stanley & Ross 1986; Halford 1998; Qld DNR 2000). Reproduction is predominantly by seeds, however, the species has been observed to produce roots from branch nodes where the branches come in contact with the soil surface. Observations of the population on Mt Tinbeerwah indicate that the plants are fire-sensitive. The species does not appear to have a lignotuber or similar root structures so regeneration after fire relies on the successful germination of seed (Halford 1998).
Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) is easily distinguished from other Prostanthera species in south-east Queensland by its obovate to more or less spathulate leaves (Halford 1998).
Innapropriate fire regimes
Anecdotal evidence suggest that Prostanthera sp. Mt Tinbeerwah (P.R.Sharp 4781) is fire sensitive and is not capable of regenerating from underground organs. Fire is a threat at all sites. Continued existence of the species after fire would require the regeneration of the species from seed (obligate seeder). Local extinction would occur if fires were too frequent and did not allow the replenishment of the seedbank. The habitat at Mt Tinbeerwah may provide some degree of protection from frequent burning as the rocky outcrops and pavements buffer plants from fire (Halford 1998).
Weed invasion of habitat is a threat, and the following weeds have been identified at Mt Tinbeerwah (Tewantin State Forest): Cobbler's Pegs (Bidens pilosa), Brachiaria decumbens, Tall Fleabane (Conyza sumatrensis), Mexican Lovegrass (Eragrostis mexicana subsp. mexicana), Sweet Potato (Ipomoea batatas), Lantana (Lantana camara), Molasses Grass (Melinis minutiflora) and Red Natal Grass (M. repens) (Halford 1998).
Lack of secure tenure
Two of the four known sites are on freehold land where changes of land management may lead to the destruction of the populations. The lack of secure land tenure for these two sites is a direct threat to the long term viability of the species at those sites and possibly to the long term viability of the species as a whole (Halford 1998).
Refer to the Commonwealth Conservation Advice (TSSC 2008aga) for information on research priorities and recovery priority actions to mitigate threats including habitat loss, disturbance and modification, weeds, grazing and fire. Raising awareness of the species and enabling recovery of additional populations are also encouraged in the Advice.
