The Spiral-fruited Wattle is a sprawling shrub to 0.7 m high and up to 3 m wide (Stack & English 1999a) with golden, obloid to short cylindrical flower-heads (Orchard & Wilson 2001a).

This species has been recorded in the past over a range of almost 250 km, from north of Watheroo to the Swan River near Perth. The majority of these collections were made over a range of about 20 km to the north of Watheroo, but most of these roadside populations appear to have been lost. Only one population is currently known to exist. This consists of two subpopulations, growing within 1 km of each other on a disturbed roadside adjoining private property (Brown et al. 1998; Stack & English 1999a).

The species does not occur naturally in a conservation reserve (Briggs & Leigh 1996). However, since 1998, it has been planted and established successfully in disused gravel pits in a nature reserve near Watheroo (Stack & English 1999a; Monks & Coates 2002).

This species occurs in disturbed roadsides on often gravelly, clayey sand over laterite (Stack & English 1999a; Paczkowska & Chapman 2000). The vegetation is low open scrub with Allocasuarina campestris, Hakea scoparia and other Acacia species (Stack & English 1999a).

Flowers are borne June-Aug (Maslin & Chapman 1999; Stack & English 1999a; Orchard & Wilson 2001a). Mature pods have been collected in Nov. and Dec. (Maslin & Chapman 1999).

Low fruit production has been observed due to predation and insect galling of the flower. Studies indicate that seeds are patchily distributed in the soil and that germinations is increased by scarification or exposure to heat. It has been demonstrated that experimental fires can break seed dormancy and promote germination (Buist et al. 2002).

Size class structure, levels of canopy death and an absence of juveniles indicate that all populations are in decline. All populations were capable of producing viable seed but seed production varied considerably between years and populations (Buist et al. 2002).

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.
