Description

Acacia eremophiloides is a resinous (slightly sticky) shrub growing to 2.5m tall and has slender branches. The phyllodes (the part of the leaf stalk taking the form of a leaf) are spreading to erect, linear in shape, 4.0-6.5cm long and 2.5-3.0mm wide, with one longitudinal vein (midrib). The phyllodes are thick and have prominently raised translucent margins and midrib.
Masses of golden-yellow flowers are produced in globular heads of about 30 flowers. The pods are linear, raised over the seeds, cinnamon brown in colour and 8cm long by 3.5cm wide. The seeds are 3.3mm long.
A. eremophiloides is distinguished from the related A. ixodes by the thicker, more resinous phyllodes with raised translucent margins and midrib, and by the more elongate pods. (Pedley & Forster 1986; Williams 1999; Maslin et al. 2001; DEWHA 2008)

Range derivation

Range derived from extent of the taxon's verified records

Habitat

Acacia eremophiloides is found predominantly in open forest or open woodland with an open to sparse shrub understorey. It grows on exposed rocky granite ridges and in open communities among large granite boulders. It occurs on shallow, sandy, well-drained soils, comprising decomposed granite and organic matter. A. eremophiloides is found at altitudes between 460-550m. (Pedley & Forster 1986; Maslin et al. 2001; DEWHA 2008)

Behaviour

Any fire that kills the foliage of this plant is fatal. Work on seed biology for A. eremophiloides was undertaken over two successive years. Although it flowered prolifically, it did not produce seed. This may be a result of dry climatic conditions, or may be a result of the low genetic diversity of the species. (Leverington et al. 2006)

Reproduction

Acacia eremophiloides flowers in August and September, with mature fruits occurring in November. The species is an obligate seeder. From seed, plants reach reproductive maturity at three to four years. In cultivated specimens are known to live for 8 to 12 years. (Leverington et al. 2006; DEWHA 2008)
