This species is an erect, multi-stemmed shrub to c. 3 m high with pale yellow flowers (Johnson et al. 1997; Walsh & Entwisle 1999). Branches are covered with star-shaped hairs. Leaves are whitish below, sometimes with scattered larger rusty-coloured hairs (Walsh & Entwisle 1999).

This species is a Victorian endemic. It is known from only one locality at Carboor Upper, beside Hurdle Ck, near Wangaratta in north-eastern Vic. (Walsh 1992b; Johnson et al. 1997; Walsh & Entwisle 1999). In 1997, the population comprised 204 plants covering 0.3 ha adjacent to a Pinus radiata plantation (Johnson et al. 1997). It is almost entirely on Crown land managed by the Victorian Plantations Corporation. There were four plants on adjoining private land (Walsh 1992b; Johnson et al. 1997).

First described by Walsh (1992b). Prior to that, it had been identified as P. pauciflora but can be distinguished because it has only star-shaped hairs, and no unbranched ones, on branchlets and the undersurface of the leaves (Walsh & Entwisle 1999).

This species grows on a steep, rocky slope with a south-easterly aspect, 50 m above a small perennial creek. The soil is shallow and derived from Ordovician sediments. Annual rainfall is about 1000 mm. The altitude is c. 320 m (Walsh 1992b).

Concave Pomaderris occurs in dry woodland (Walsh & Entwisle 1999). It is the dominant species and forms a dense shrubland in a small remnant of modified Grassy Dry and Valley Grassy Forest (NRE 1996 in Johnson et al. 1997). Overstorey in the heart of the stand is largely absent because of clearing in the past. However, a scattering of Eucalyptus goniocalyx, E macrorhyncha and Acacia dealbata overlaps and continues beyond the perimeter of the stand (Johnson et al. 1997). A dense layer of bracken fern (Pteridium esculentum) occurs to the east and downslope on deeper soils (Walsh 1992b).

Plants flower Oct.-Dec. (Johnson et al. 1997; Walsh & Entwisle 1999).

Propagation trials suggest seed production and viability may be low (Johnson et al. 1997). The modified landscape of the Carboor Upper population as native forest surrounded by pine plantations and cleared grazing land, may be unable to attract suitable pollinators, and this may result in low seed production (Johnson et al. 1997)

Although the population contains a spread of all age classes, senescence (decline) of mature individuals has been observed in 65% of the population, and only 22 seedlings have been recorded. However, approximately 10% of the senescent plants are resprouting with new growth from the base (Johnson et al. 1997).

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.
