Acacia parvipinnula

Acacia parvipinnula, commonly known as silver-stemmed wattle, is a species of Acacia native to eastern Australia.

Description
The shrub or tree typically grows to a height of 2 to 10 m and has an erect habit. It has silvery to bluish grey smooth bark and angled to erect branchlets that have low ridges and are often covered in a fine white powder and are densely covered with minute hairs. The leaves are 0.5 to 1.7 cm in length and are also hairy with a rachis that has a length of 1.5 to 8 cm and contain 4 to 13 pairs of pinnae that are 1 to 5 cm long and composed of 13 to 42 pairs of pinnules that have a narrowly oblong shape with a length of 2 to 4 mm and a width of 0.5 to 1 mm. It blooms between April and January producing simple inflorescences in both axillary and terminal panicles and racemes on stalks that are 2 to 5 mm in length. The spherical flower-heads have a diameter of 4 to 6 mm and contain 14 to 20 pale yellow flowers. Following flowering straight to curved seed pods form that are a little and usually irregularly more deeply constricted between seeds. The leathery pod are sparsely haired and are around 2 to 17 cm in length and 5 to 8.5 mm wide.

Distribution
It has a limited distribution in coastal areas of central New South Wales from around Singleton to around the Shoalhaven River where it is found in a variety of habitats growing in many different soil types as a part of dry sclerophyll forest or woodland communities.

Cultural significance
In the Dharawal story of the Boo’kerrikin Sisters, one of the kindly sisters was turned into Acacia parvipinnula. The other two sisters were turned into Acacia decurrens and Acacia parramattensis.
