The Large-fruited Tammin Wattle is a sprawling semi-prostrate or ascending shrub to 0.3-0.6 m high and 0.5 m wide with globular to slightly ovoid yellow flower heads (Brown et al. 1998; Maslin 1999; Paczkowska & Chapman 2000; Orchard & Wilson 2001).

This species appears to be confined to the Tammin area in the wheatbelt of south-western WA (Brown et al. 1998; Maslin 1999; Orchard & Wilson 2001). Three of the populations located over the last 30 years appear to have become extinct, however several new populations have been found by WA CALM officers (Brown et al. 1998). Briggs & Leigh (1996) recorded it in Charles Gardner Flora Reserve.

Brown et al. (1998) stated that there were fewer than 50 known plants and that all populations are restricted to narrow road reserves.

It grows in sand over laterite on ironstone rises and flats amongst low heath (Brown et al. 1998; Maslin 1999; Paczkowska & Chapman 2000; Orchard & Wilson 2001). It has very specific habitat requirements (Brown et al. 1998).

The flowers are borne May-Aug. (Brown et al. 1998; Maslin 1999; Orchard & Wilson 2001). Pods have not been collected (Maslin 1999).

The species is a geographically restricted disturbance opportunist (Brown et al. 1998).

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.
