The Watheroo Wattle is an erect or scrambling shrub growing to 1 m high, and up to 1 m wide (Brown et al. 1998; Maslin 1999; Paczkowska & Chapman 2000; Orchard & Wilson 2001).

The species is confined to the Moora-Watheroo area of SW WA (Brown et al. 1998). First collected in 1974, it has been recorded from four localities over a geographical range of 35 km (Patrick & Brown 2001). The species is only known from two general localities; Jingemia Hill in Watheroo NP, and the type locality, c. 25 km S towards Moora (Maslin 1999; Orchard & Wilson 2001).

The species is usually associated with outcrops on low rocky ridges and hills; in brown sandy clay loam over granite and chert (Brown et al. 1998; Maslin 1999; Paczkowska & Chapman 2000; Orchard & Wilson 2001; Patrick & Brown 2001). It grows in Allocasuarina woodland or low open shrubland (Brown et al. 1998; Maslin 1999; Orchard & Wilson 2001; Patrick & Brown 2001). Associated species are Allocasuarina huegeliana, Diplolaena angustifolium, Dianella revoluta, Kennedia prostrata and Dryandra sessilis (Brown et al. 1998; Patrick & Brown 2001).

The globular flower heads are pale lemon yellow or creamy white. The flowers begin in Sept./Oct. and probably extend to Jan or Feb (Brown et al. 1998; Maslin 1999; Paczkowska & Chapman 2000). The fruits probably take about a year to mature (Maslin 1999).

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.
