The Ironcap Boronia is an erect much-branched shrub varying in height between 0.5 and 1.5 m, with pale to dark pink flowers (Wilson 1971; Leigh et al. 1984; Hopper et al. 1990; Duretto 1999b).

This species occurs over a range of about 40 km in the South Ironcap-Hatter Hill area, NE of Lake King, south-western WA (Wilson 1971; Leigh et al. 1984; Hopper et al. 1990; Brown et al.1998). It has only been collected from three locations (Brown et al. 1998; Duretto 1999b).

It was thought to be extinct at one location until collected there in small numbers in 1989. Further surveys in 1992 and 1993 failed to find any plants. It was reported at the second location, Middle Ironcap (north of South Ironcap) in 1976, but extensive searches in 1992 did not locate any plants (Brown et al. 1998; Duretto 1999b). In 1998, it was still present at the third location (Brown et al. 1998).

This species is probably restricted to ironstone hills (Wilson 1971; Leigh et al. 1984; Hopper et al. 1990; Brown et al. 1998; Duretto 1999b) growing in cracks in the rock (Brown et al. 1998).

It grows in either low eucalypt woodland or semi-arid mallee scrub (Wilson 1971; Leigh et al. 1984; Brown et al. 1998), but also reported as growing in heath (Hopper et al. 1990; Brown et al. 1998; Duretto 1999b).

Flowering occurs July-Oct. (Brown et al. 1998; Duretto 1999b) with fruiting observed Sept.-Dec. (Duretto 1999b).

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.
