Description

The shrub is slender and erect typically growing to a height of 1.3 metres (4 ft)[1] with a spindly habit. It has terete, finely veined and densely haired branchlets that are mostly brown but quite yellowish towards the apices. Like most species of Acacia it has phyllodes rather than true leaves. The flat, linear and evergreen phyllodes are pressed closely to the stems and have a length of 2 to 4.5 cm (0.79 to 1.77 in) and a width of 1 to 3 mm (0.039 to 0.118 in). The phyllodes have 1 to 3 mm (0.039 to 0.118 in) long seta that are softy puberulous and have one prominent main vein with multiple parallel minor veins.[2] It blooms between May and June or in October to November producing yellow flowers.[1] The cylindrical flower-spikes have a length of 2.5 to 3 cm (0.98 to 1.18 in) and are densely packed with golden flowers. The narrowly oblong seed pods that form after flowering have fairly straight sides and are straight to slightly curved with a length of 4.5 to 6 cm (1.8 to 2.4 in) and covered with matted golden wooly hairs that age to a white colour. The black seeds inside are arranged obliquely and have an oblong shape with a length of 4 to 4.5 mm (0.16 to 0.18 in).[2]

Distribution

It is native to an area of the Kimberley region of Western Australia.[1] The shrub grows in sandy alluvium especially along watercourses[1] in remote areas from around the Gibb River to around Karungie Station as a part of open Eucalyptus savannah communities.[2]
