The Ironcaps Banksia is a shrub or small tree growing to 4 m and spreading to 4 m in diameter with golden/yellow flowers (George 1981, 1999; Hopper et al. 1990) and a dense canopy (Hopper et al. 1990).
This species occurs just to the east of the cleared southern wheatbelt in south-western WA. It grows between Mt Holland and South Ironcap, east of Hyden, on vacant Crown Land (Mollemans et al. 1993; Brown et al. 1998). Surveys carried out in 1989/90 showed seven populations totalling over 2,400 plants (see table below). By 1994 there were nine populations with a total of about 6,500 plants. The impact of a 1994 fire is not known (Brown et al. 1998).
Details of populations as in Mollemans et al. (1993):
|Population [as numbered by|
|Location||Land Status||Year of survey/|

|1||Mt Holland||Vacant Crown Land/Water Reserve||1990 - 300||Barrow Pit Damage|
|2||N of Lake Cronin||Vacant Crown Land||1989 - 50+||Good|
|3||S of pop. 2||Vacant Crown Land||1989 - 400+||Good|
|4||North Ironcap||Vacant Crown Land||1989 - 100+||Good|
|5||Forrestania||Vacant Crown Land||1990 - 50+|
|6||South Ironcap||Vacant Crown Land||1990 - 1000+||Good - 1989; some damage by surveyors - 1990|
|7||SE of South Ironcap||Vacant Crown Land||1989 - 500+||Good|
This species has a preference for iron-capped hills and rises on ironstone (lateritic) soil profiles. It is found in low woodlands to low shrublands; associated plants include Dryandra and Allocasuarina species (George 1981; Patrick & Hopper 1982; Taylor & Hopper 1988; Hopper et al. 1990; Mollemans et al. 1993; George 1999). The annual rainfall in the region is 300 mm (George 1996b).
The species possesses a lignotuber and is fire tolerant (George 1996b; Brown et al. 1998). Flowering occurs from Mar.to May (George 1981; Patrick & Hopper 1982; Hopper et al. 1990; George 1996b, 1999). Bees, wasps and ants are recorded as pollinators (Taylor & Hopper 1988).
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.
