Acacia leptoneura is a shrub standing approximately 0.6 m high and 2.2 m wide. It flowers in August and sets fruit in November and December and is predicted to be short to medium lived (10-15 years, based on life span of A. subflexuosa). A. leptoneura is very similar to A. subflexuosa, which differs most obviously in having 8-nerved phyllodes, whereas A. leptoneura has 16-nerved phyllodes. Phyllodes shallowly to strongly incurved or sigmoid, terete to subterete, 3–7.5 cm long. Inflorescences simple, 1 or 2 per axil; peduncles 4–6 mm long, sparingly appressed-puberulous; heads globular, c. 5 mm diam., 20–30-flowered; bracteoles linear to fusiform. Flowers 5-merous; sepals free, linear-spathulate. Pods raised over seeds, curved, to 3 cm long, 2 mm wide. Seeds 2 mm long, dull, brown

Future threats Climate change resulting in reduced optimal conditions for seedling survival when recruitment events occur.
Current threats Habitat fragmentation; roadside grading accidental destruction; stock movement along roadsides; herbivore grazing; herbicide spray drift; lack of suitable recruitment; very low adult plant numbers genetic diversity; weeds and inappropriate fire regimes.
