The Tangled Wattle is a dense, compact, domed, wiry entangled shrub (Maslin 1995; Paczkowska & Chapman 2000), growing to 0.3-0.4 m high to 1 m wide (Paczkowska & Chapman 2000) with yellow globular flower heads (Brown et al. 1998; Paczkowska & Chapman 2000; Orchard & Wilson 2001).

This species is known only from the Cunderdin area in the wheatbelt area of south-western WA (Brown et al. 1998; Orchard & Wilson 2001). It was originally known only from a late 19th century collection from 'Boxvale', and an unknown locality, possibly near Quairading, about 70 km ESE of York, south-western WA (Maslin 1995; Orchard & Wilson 2001). The species was presumed to be extinct (Maslin 1995; Briggs & Leigh 1996) until a small population was discovered near Cunderdin in June 1996. A few populations are now known in the area, consisting of only a few plants each, on degraded road reserves (Brown et al. 1998).

Specimens of A. carens and A. cummingiana were formerly confused with A. volubilis (Orchard & Wilson 2001).

This species grows in gravelly sandy clay loam (Paczkowska & Chapman 2000; Orchard & Wilson 2001). The species grows on extremely degraded road reserves with little native vegetation (Brown et al. 1998).

Flowers appear in June (Brown et al. 1998; Paczkowska & Chapman 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.
