Latz's Wattle is a bushy shrub or tree 3-8 m high with thick rough bark (Maslin 1980; Jessup 1981; Orchard & Wilson 2001a; Kerrigan et al. 2002a).

This species has a disjunct distribution in southern NT extending over the border to far northern SA. It is known only from two areas 230 km apart:
1. the Bacon Range, c. 130 km south-west of Alice Springs, NT; and
2. the Beddome Range, 110 km east of the Stuart Highway, on the NT/SA border.
(O'Malley 2000; Orchard & Wilson 2001a)

The Bacon Range population occurs west of the Henbury meteorite craters (O'Malley 2000) on Henbury and Tempe Downs Station (Maslin 1980; Jessop 1981; Leigh & Briggs 1992). The population on Henbury Station consists of four small stands scattered over 25 km (Leigh & Briggs 1992; Kerrigan et al. 2002a). The population is healthy, containing mature seeding trees, but juveniles are rare. Two small enclosures have been built to protect some individuals (SGAP 1993).

The Beddome Range population occurs on New Crown Station, NT and Tieyon Station in SA. The full extent of this population is unknown but the species is described as extremely rare in SA (Maslin 1980; Jessop 1981; Leigh & Briggs 1992; Orchard & Wilson 2001a; Kerrigan et al. 2002a).

This species is not known to occur in any conservation reserve (Briggs & Leigh 1996; Kerrigan et al. 2002a).

Apparently related to A. calcicola but can be readily distinguished by its flower-heads which have fewer flowers and its non-woody and linear (rather than bead-like) pods (Orchard & Wilson 2001a).

This species typically occurs on shallow gravelly soils in small watercourses, gullies and rocky slopes (Leigh & Briggs 1992; Orchard & Wilson 2001a; Kerrigan et al. 2002a). It is found in low hilly country and favours saline, alkaline skeletal soils (Latz, P.K. pers. comm. in Maslin 1980; Jessop 1981; Leigh & Briggs 1992; Orchard & Wilson 2001a). These hills often form mesas or buttes, and have a hard silcrete capping underlain by clay, siltstone and shale (Leigh & Briggs 1992).

A. latzii often grows in pure stands (Kerrigan et al. 2002a). It is locally dominant in tall open shrubland, or with A. aneura (Orchard & Wilson 2001a). There is often a sharp boundary between the Acacia species, with A. latzii growing on lighter coloured silcrete-type soils; and the similar A. aneura growing on adjacent footslopes with red earth soils (SGAP 1993).

The yellow, globular flower heads (Leigh & Briggs 1992; Orchard & Wilson 2001a) are borne Apr.-Aug. (Maslin 1980; Leigh & Briggs 1992; Kerrigan et al. 2002a). Fruiting occurs May, Jul. to Nov.

The population of A. latzii is skewed towards the oldest age classes; there is no evidence of recent recruitment within known stands (Kerrigan et al. 2002a). The species only produces seed during good seasons, which occur every 5-10 years (Leigh & Briggs 1992). Research indicates that Latz's wattle needs an exceptional rainfall event to trigger widespread seed production, and then probably requires good follow-up rains to allow germination and seedling survival (Lake Eyre Basin Coordinating Group 2000).

Monitoring of fenced plots at Henbury over the past seven years indicates that there has been little change in population numbers. Although seed set has occasionally been recorded, there has been no germination. (O'Malley 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.
