An erect open shrub or small tree (Paczkowska & Chapman 2000; Orchard & Wilson 2001a) to 4 m high (Simmons 1988; Hopper et al. 1990; Mollemans et al. 1993; Brown et al. 1998; Paczkowska & Chapman 2000; Orchard & Wilson 2001a).

Populations are scattered from east of Mt Churchman, south to near Nungarin, and west to Wongan Hills (Orchard & Wilson 2001a); in the Wheatbelt Region of south-western WA (Simmons 1988).

The species was originally known from fifteen populations at two general localities (Wongan Hills and Mukinbudin), over a 150 km range. It is now extinct at the type locality, Mt Churchman, due to prolonged drought. The species is now known from eight populations over a range of 180 km, including two populations found in 1989 in the Karroun Hill area (Mollemans et al. 1993; Brown et al. 1998). Some populations have declined from more than 200 plants in 1984 to fewer than 100 in 1996 (Brown et al. 1998).

The species is conserved in Karroun Hill NR (Briggs & Leigh 1996).

Usually grows in shallow sandy soils, on granite outcrops and sheet granite (Simmons 1988; Hopper et al. 1990; Mollemans et al. 1993; Brown et al. 1998). Soils are sand, loam, silt and clay. Found on and around granite hills and outcrops, or more rarely on sandplains (Paczkowska & Chapman 2000; Orchard & Wilson 2001a). The sites are prone to severe drying out (Simmons 1988).

The flower heads are dense yellow curved spikes (Hopper et al. 1990; Mollemans et al. 1993; Brown et al. 1998; Paczkowska & Chapman 2000; Orchard & Wilson 2001a). Flowers are borne Aug.-Nov. (Hopper et al. 1990; Mollemans et al. 1993; Brown et al. 1998). Seed matures Dec.-Jan. (Mollemans et al. 1993).

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.
