About Acacia oshanesii F.Muell. & Maiden
Acacia oshanesii F.Muell. & Maiden is an erect shrub or tree that typically grows to a height of 2 to 12 m (6 ft 7 in to 39 ft 4 in). It has grey, green, or brown bark with a smooth or slightly fissured texture. Its branchlets range from angled to terete, with fine yellowish brown to white hairs growing along their ridges. This species has filiform leaves with a 2.5 to 12 cm (0.98 to 4.72 in) long rachis, which bears 7 to 27 pairs of pinnae measuring 1 to 4.7 cm (0.39 to 1.85 in) in length. In turn, the pinnae hold 14 to 51 pairs of glabrous pinnules. Pinnules have an oblong to narrowly oblong shape, measuring 1 to 3 mm (0.039 to 0.118 in) long and 0.5 to 0.7 mm (0.020 to 0.028 in) wide. It produces yellow flowers throughout the year. Its simple inflorescences grow in axillary racemes, and take the form of spherical flower heads that hold 12 to 25 pale yellow or cream-coloured flowers. After flowering, coriaceous brownish black to bluish-black seed pods develop. The pods are usually curved, with a length of 3 to 14 cm (1.2 to 5.5 in) and width of 7 to 12 mm (0.28 to 0.47 in). The species is native to north eastern New South Wales in Australia, ranging from around Bellingen and Coffs Harbour in the south northward into south eastern Queensland. It grows across a variety of habitats in gravelly, clay, sandy, or loamy soils, as a component of wet sclerophyll forest and rainforest plant communities. Its entire range extends from around Maryborough in the north down to around Stanmore in the south, and it occurs in high-rainfall, low-altitude coastal areas.
