The Sandy Hollow Commersonia is a prostrate shrub growing 0.1-0.3 m high, producing trailing branches up to 60 cm long. Branches are densely stellate-hairy (especially on young growth), becoming almost hairless and channelled on older branches. The leaves have a petiole 4-10 mm long, persistent linear stipules, 6-9 mm long and 1 mm wide, and blades that are narrowly oblong to narrowly elliptic, 24-70 mm long, 8-17 mm wide, and stellate-hairy on both surfaces. The inflorescence is arranged as one to three flowers with densely stellate-hairy stalks 2-8 mm long. Flowers have five pink, three-lobed petals. Fruit capsules are globe-shaped, lime-green turning pale brown with age, 10-16 mm diameter, and densely covered in 2-4 mm long bristles (DECC 2005b).

Sandy Hollow Commersonia is only known from four localities in the Sandy Hollow district of the upper Hunter Valley, NSW, all within an 8 km radius of Sandy Hollow (NSW SC 2004).

Vegetation surveys in the nearby Manobalai Nature Reserve, Goulburn River National Park, Myambat Logistics Company site, Department of Defence, Wollemi National Park and other Crown Lands have failed to locate further populations of the Sandy Hollow Commersonia (NSW SC 2004).

Sandy Hollow Commersonia occupies relatively small areas at its known sites and has a total population of less than 200 plants (Bell & Copeland 2004). The species is known from four populations in the Sandy Hollow district of the upper Hunter Valley, NSW. The four localities (Pikes Gap, Giants Creek, Peberdys Road and Boodles Creek) fall within an 8 km radius of Sandy Hollow, within the Central Western Slopes of NSW (Bell & Copeland 2004).

No populations are within a conservation reserve (NSW SC 2004).

Sandy Hollow Commersonia occurs on skeletal sandy soils in scrub or heath vegetation with occasional emergents of Eucalyptus crebra, Callitris endlicheri or Eucalyptus caleyi subsp. caleyi (DECC 2005b).

Sandy Hollow Commersonia has been observed flowering in August, November, January and February (DECC 2005b).

Given that fire had occurred within 6-12 months prior to the location of this species at three of the four sites, it may be a fire ephemeral (that is it appears after fires) (DECC 2005b).

Threats to Commersonia rosea include environmental and demographic stochasticity due to its small population size, disturbance associated with track maintenance, changed fire regimes, and future land development should tenure change (DECC 2005b; NSW SC 2004).

Minister's reasons for recovery plan decision
The approved conservation advice for the species now provides sufficient direction to implement priority actions and mitigate against key threats. A recovery plan is not considered to be necessary at this time.

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.
