Western Australia: Listed as Critically Endangered under the name Tetratheca paynterae subsp. paynterae and Vulnerable under the name Tetratheca paynterae subsp. cremnobata under the Wildlife Conservation Act 1950.
Paynter's Tetratheca is a small, erect or decumbent shrub, growing between 0.1-0.5 m high (Alford 1995; Brown et al. 1998; Paczkowska & Chapman 2000). The leaves are sparse, 0.8-2.5 mm long, less than 1 mm wide, early deciduous or sometimes absent (TSSC 2008adl; WA DEC 2006i). The species’ flowers are deep pink with a yellow spot at the base (Brown et al. 1998; Paczkowska & Chapman 2000). Fruits are approximately 5-8 mm long and 4-6 mm wide (TSSC 2008adl).
Paynter's Tetratheca is endemic to Western Australia, where it is restricted to two locations in the Windarling Range, 160 km north of Southern Cross, in the Yilgarn region (Butcher 2007). The total area of occurrence has not been published (TSSC 2008adl).
There are two known sub-populations of Paynter’s Tetratheca. The range of one sub-population occurs over 2 km with approximately 1000 individuals (Alford 1995; Brown et al. 1998). Around 8000 plants have been recorded at the second location (see Butcher 2007). Neither sub-population occurs in a conservation reserve (Alford 1995; Brown et al. 1998; Butcher 2007).
Paynter’s Tetratheca grows in rock crevices, in shallow pockets of soil of rich red loam (Alford 1995; Brown et al. 1998; Mollemans et al. 1993; Paczkowska & Chapman 2000). The species grows in highly exposed, windswept areas (Brown et al. 1998; Mollemans et al. 1993) amongst rock, on banded ironstone hills (Alford 1995; Brown et al. 1998).
The associated vegetation community is open shrubland, which includes Wiry Honey Myrtle (Melaleuca filifolia), Leafless Ballart (Exocarpos aphyllus), Sea Box (Alyxia buxifolia), Calycopeplus spp., Dead Finish (Acacia tetragonophylla) and Sticky Hop Bush (Dodonea viscosa), over a sparse understorey of Chenopodium spp., Ptilotus spp., Olearia stuartii and Isotoma petraea (Alford 1995).
Flowers are borne from April to November, with a peak in spring (Alford 1995; Brown et al. 1998; Paczkowska & Chapman 2000), or opportunistically after rain (Alford 1995). Pollination of flowers are thought to be solitary native bees of the genus Lasioglossum (WA DEC 2006i). Despite high rates of pollination, Paynter’s Tetratheca displays lower levels of fruit production and viable seed. Fruits dehisce in late spring and the seeds are released. Seeds have a prominent eliasome and are thought to be dispersed by ants (WA DEC 2006i). Rates of germination and seedling establishment seem to be heavily dependent on rainfall (WA DEC 2006i).
Initial investigation of roots indicates that there is intricate root development within the supporting rock crevices. Research has identified that endomycorrhizal fungi occurring in association with the roots may be essential for nutrient uptake (WA DEC 2006i). Plants are well adapted for dry conditions, entering dormancy over hot, dry months and initiating new shoots in autumn (WA DEC 2006i). The development of these shoots slows or stops over winter, but re-commences in spring.
Paynter’s Tetratheca appears relatively secure, although impacts have occurred due to mining and grazing in some areas (Brown et al. 1998; Mollemans et al. 1993; WA DEC 2006i). Impacts to the remaining sub-populations are considered unlikely, however, further change to grazing regimes may adversely affect the species (TSSC 2008adl).
The Commonwealth Conservation Advice for Paynter’s Tetratheca identifies a number of on-ground and research-based recovery actions for the species. Some of these actions include:
- Monitor known populations to identify emerging threats.
- Ensure development activities do not adversely impact on known (sub)populations.
- Investigate formal conservation agreements or covenants on private land.
- Raise awareness of Paynter’s Tetratheca in the local community.
- Undertake appropriate seed collection and storage.
- Investigate options for linking, enhancing or establishing additional populations.
