A shrub growing to 2.5 m high and nearly as wide, with a very limited distribution from near Woodford to Mt Victoria, in the Blue Mountains of NSW.
Usually in damp and swampy sites next to watercourses on sandstone.
Phyllodes (modified leaves) are straight to slightly curved, terete (tubular) and linear to 8 cm long and to 0.1 cm wide, with a small mucro.
Flowers are produced in globular heads, to 7 mm diameter, with up to 40 very small staminate flowers per head, bright yellow to pale yellow, to white. Heads are produced in 1s or 2s, in the axils of phyllodes. Flowering occurs January to April.

Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these occurring.
Propagation is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.
Most wattles regenerate from seed after fire with some species exhibiting suckering from basal areas.
