Acacia pubescens, also known as the downy wattle, is a species of wattle found in the Sydney Basin in eastern New South Wales. The downy wattle is classified as vulnerable; much of its habitat has vanished with the growth of the city of Sydney. Acacia pubescens grows as a shrub to small tree from 1 to 5 m (3.3 to 16.4 ft) high. As with all wattles, it has leaf-like structures known as phyllodes instead of leaves, which are compound (pinnate) and measure 1.5–6.5 cm (0.59–2.56 in) in length. The globular yellow flowers appear in spring (August to October).
