Acacia eremophiloides is a resinous shrub to 2.5 m high with slender branchlets (Pedley & Forster 1986; Orchard & Wilson 2001).

Restricted to a small area in the Burnett Pastoral District of south-eastern Qld. The species grows 46 km south-south-west of Gayndah and 45 km south-east of Mundubbera and has a distributional range of less than 10 km. It occurs as a number of discontinuous populations on leasehold and freehold land currently used for cattle grazing, and may be locally common. (BRI undated; Pedley & Forster 1986).

The species is known only from the northern part of Beeron Holding where there are at least 10 populations containing a total of more than 5000 individuals ((Leverington et al. 2003).

Formally described in 1986, it is closely allied to A. ixodes but differs in having thicker, more resinous phyllodes with translucent margins and midribs, and more elongated pods (Pedley & Forster 1986). It is also related to A. gnidium and A. hockingsii but differs in the size and shape of its phyllodes (Orchard & Wilson 2001).

The species occurs at altitudes between 460-550 m on exposed rocky granite ridges in shallow, sandy, well-drained, weakly acidic soils (Pedley & Forster 1986). The climate is subtropical and subcoastal, with hot, moist summers and mild, dry winters (Leverington et al. 2003).

Associated species include Hibiscus sp. (Barambah Creek), Leptospermum neglectum, Trachymene procumbens, Hybanthus monopetalus, Hoya australis, Hibbertia linearis and Psilotum nudum (Pedley & Forster 1986). A. eremophiloides also occurs with Newcastelia velutina and Acacia porcata (Halford, D. 2001, pers. comm.).

Surrounding vegetation is predominantly open forest or open woodland with an open to sparse shrub layer. In the upper stratum, Eucalyptus exserta, Eucalyptus petalophylla and Eucalyptus dura dominate, with Acacia grandifolia, Allocasuarina inophloia and Callitris endlicheri occurring occasionally. The understorey is diverse in composition and structure. Much of the area is dominated by Triodia pungens. Other frequent species are Leptospermum polygalifolium, Xanthorrhoea johnsonii, Acacia eremophiloides, Cleistochloa rigida, Pomax umbellata and an unidentified species of Aristida (Leverington et al. 2003).

Weed invasion and soil degradation are minimal. The habitat of the area is considered to be in relatively undisturbed condition (Leverington et al. 2003).

Flowers recorded Aug. and Sept; mature fruits Nov. (BRI undated; Pedley & Forster 1986).

There appears to be a close relationship between seedling recruitment and fire. Factors affecting seed production may also influence recruitment of A. eremophiloides. Plants produced no seed at observed sites over two successive years, although they flowered profusely. This may be due to climatic conditions, or may be the result of low genetic diversity. It is suspected that the species usually seeds irregularly (Leverington et al. 2003).

The species has low genetic diversity. Its genetic profile suggests that the species has been geographically isolated from near relatives, has developed in isolation, possibly during the Quaternary period, and has adapted to relatively harsh edaphic conditions (Leverington et al. 2003).

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.
