The Chiddarcooping Wattle is an erect, open and often spindly shrub, 1-2 m high with yellow, globular flower heads (Orchard & Wilson 2001a).

This species is known from the Chiddarcooping Hill area (Mollemans et al 1993; Brown et al. 1998) near Warralakkin (Hopper et al. 1990), about 70 km NE of Merredin (Orchard & Wilson 2001a) in the NE Wheatbelt of SW WA (Buist et al. 2000).

The relatively recent discovery of a new population increased the known range of the species to 20 km, and the total number of populations to three (Buist et al. 2000). Previously the species was known by two populations with a geographic range of 17 km (Mollemans et al 1993; Brown et al. 1998).

Two populations, with plant numbers exceeding 5000, occur in nature reserves (Buist et al. 2000; Buist et al. 2002) including Chiddarcooping NR (Cowan & Maslin 1990; Briggs & Leigh 1996). The third population, of 116 plants, occurs essentially on a shire road reserve, but extends into adjacent private property. The taxon is highly restricted but locally abundant (Buist et al. 2000; Buist et al. 2002).

It is presumed to be a relict species (Buist et al. 2000).

This species is closely related and morphologically similar to Acacia verricula which occurs in the same area (Buist et al. 2002).

This species grows in gritty clay loam and sand, on gradual slopes, at the foot of low decomposing granite breakaways (Cowan & Maslin 1990; Hopper et al. 1990; Mollemans et al 1993; Brown et al. 1998; Buist et al. 2000; Paczkowska & Chapman 2000; Orchard & Wilson 2001a).

It occurs in Eucalyptus capillosa woodland and tall Melaleuca uncinata shrubland (Buist et al. 2000) and grows in association with Eucalyptus spp. and Oxylobium parviflorum. The species is occasionally found in woodland dominated by E. wandoo (Cowan & Maslin 1990).

Flowers are borne June-July (Hopper et al. 1990). Mature fruit have been collected in Nov. (Cowan & Maslin 1990; Mollemans et al 1993; Brown et al. 1998).

All populations show an absence of recruitment. The species' response to fire is unknown (Buist et al. 2000).

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.
