The Dandaragan Wattle is a tall spindly shrub 1-4 m high, or rarely a tree of 5-6 m high (Hopper et al. 1990; Brown et al. 1998; Paczkowska & Chapman 2000; Orchard & Wilson 2001) with globular golden flower heads (Brown et al. 1998; Orchard & Wilson 2001).

This species occurs in the Badgingarra-Dandaragan area in south-western WA (Brown et al. 1998). There are two populations, 8 km apart (Brown et al. 1998; Patrick & Brown 2001; Phillimore & English 2000).

The larger population straddles private land and a road reserve. It contained more than 100 plants and was in good condition when surveyed in 1991 (Brown et al. 1998; Patrick & Brown 2001). A later report estimated that it consisted of as many as 25 000 reproductive plants and noted that it was mainly on private land (Buist et al. 2002).

The smaller population is located on private land NNW of Dandaragan and 8 km north of the other population (Orchard & Wilson 2001; Patrick & Brown 2001). It consisted of 'a few' plants in 1992 (Brown et al. 1998; Patrick & Brown 2001).

Formerly known as Acacia sp. D (Orchard & Wilson 2001).

The taxon is currently undescribed and there is uncertainty about its taxonomic status in relation to its common and widespread relative A. microbotrya (Buist et al. 2002). A. sp. Dandaragan differs in the thick, waxy, powdery coating on its branchlets, the length of its racemes and the shape and colour of its flower heads (Brown et al. 1998).

A. sp. Dandaragan differs in the thick , waxy, powdery coating on its branchlets, the length of its racemes and the shape and colour of its flower heads (Brown et al. 1998).

The species grows in a lateritic breakaway system on brown gravelly loam on slopes and alluvial flats (Hopper et al. 1990; Brown et al. 1998; Paczkowska & Chapman 2000; Orchard & Wilson 2001; Patrick & Brown 2001; Buist et al. 2002).

Flowers are borne Aug.-Sept. (Brown et al. 1998) or May-June (Paczkowska & Chapman 2000).

The species germinates from seed in the soil bank and also spreads by extensive root suckering. Therefore it is likely to be resilient to fire (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.
