- Description
- Acacia deuteroneura is a shrub to 3 m high with glabrous and pruinose branchlets. The phyllodes are blue-green in colour, 3 to 6 cm long and 6 to 12 mm wide, glabrous and coriaceous. They are narrowly elliptic to oblong-elliptic in shape with an obtuse apex. The midrib is prominent, with a minor nerve parallel to the midrib for ? length of the phyllode. The lateral nerves are few and obscure. There is a prominent gland, 10 to 18 mm above the pulvinus, and there is occasionally a second gland above the middle. The inflorescences are racemose, with the raceme axes 3 to 5 mm long and the peduncles 3 to 9mm long, both are pruinose and glabrous, they occur as yellow globular heads with 12 to 30 flowers. The pods are 5cm long and 12 to 13 mm wide, firmly chartaceous, pruinose and glabrous. The seeds are 3.5 to 4 mm long, dull black in colour and the funicle encircles three quarters of the seed in a double fold. The aril is clavate (Pedley, 1979; Maslin, 2001).
In the field A. deuteroneura may be confused with A. decora and A. polifolia which are commonly found in the same area, but the latter two are readily distinguished by their 1-nerved phyllodes, hairy racemes and peduncles, and funicles which do not encircle the seeds (Pedley, 1979; Maslin, 2001). - Map

- Distribution
- Acacia deuteroneura is known from two locations: one 64 km north-north-east of Tambo in central western Queensland, growing on a knoll of weathered sandstone with Eucalyptus bakeri (Pedley, 1969; Maslin, , 2001; Queensland Herbarium, 2011) and the other from 60 km north of Tambo (Queensland Herbarium, 2011). There are only two specimens of A. deuteroneura in the Queensland Herbarium, collected in 1968 and 1973 (BRI collection details, n.d.). The collecting notes for the 1973 specimen describe the species as forming almost pure stands.
There are large areas of similar habitat to the north and south-east of the only known population and Pedley (1979) suggested that the species may prove to be more widely distributed. However, no further collections of A. deuteroneura have been made (Queensland Herbarium, 2011). - Distributional limits

- Range derived from extent of the taxon's verified records
- Habitat
- Acacia deuteroneura has been recorded on a weathered sandstone knoll with Eucalyptus bakeri (Queensland Herbarium 2011).
- Reproduction
- Little is known on the biology and ecology of A. deuteroneura. Flowering has been recorded in August and fruiting in November (DSEWPC, 2008; Queensland Herbarium, 2011)
- Threatening processes
- Research is needed to identify the threats to A. deuteroneura. The known range of the species is very restricted, so it is likely to be susceptible to elimination by stochastic events. Too- frequent fire may deplete the soil seed bank (DSEWPC, 2008).
- Status notes
- Acacia deuteroneura is listed as Vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 and Vulnerable under Queensland's Nature Conservation Act 1992
- Management documents
- Nature Conservation (Protected Areas) Amendment Regulation (No.1) 2001 details A. deuteroneura habitat management within Rainmore Nature Refuge (QSL, 2001).
- Management recommendations
- Management recommendations for Acacia deuteroneura are listed in Species Profile and Threats Database (DSEWPC. 2008). Regional and local priority actions are described which include: avoiding habitat loss, disturbance and modification (e.g. do not permit further clearing of potential habitat, and careful assessment of development applications; monitor known populations); managing fire (e.g. development and implementation suitable fire management strategy); raising conservation awareness of the species (e.g. raise awareness in the local community) and enabling recovery of additional sites and/or populations (e.g. research into regeneration and seed-set requirements; seed collection and storage) (DSEWPC. 2008).
- Notes
- Occurs in the following Queensland pastoral districts: Mitchell (Queensland Herbarium 2011).
