Acacia signata is a species of tree or shrub in the family Fabaceae that is endemic to western Australia.
The slender, straggly, weeping tree or shrub typically grows to a height of 1 to 4 metres (3 to 13 ft).[1] The pendulous or arching branchlets are often covered in a fine white powder. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen phyllodes usually have a pendulous forn with a linear to linear-elliptic shape and are straight to slightly curved. The grey-green and coriaceous phyllodes have a length of 10 to 20 cm (3.9 to 7.9 in) and a width of 4 to 10 mm (0.16 to 0.39 in) and have numerous fine nerves numerous and a prominent yellow coloured pulvinus.[2] It blooms from August to October producing yellow flowers.[1] The inflorescences occur in groups of one to four flower-spikes with a cylindrical shape. The spikes have a length of 12 to 23 mm (0.47 to 0.91 in) and a diameter of 6 to 7.5 mm (0.24 to 0.30 in). The coriaceous seed pods that form after flowering have a curved to linear shape and are raised over seeds. The pods have a length of up to 7 cm (2.8 in) and have a width of 5 to 6 mm (0.20 to 0.24 in) and are glabrous with a powdery white coating. The glossy dark brown seeds inside are arranged longitudinally and have a compressed subdiscoid shape with a length of 4 to 4.5 mm (0.16 to 0.18 in).[2]
Taxonomy
The species was first formally described in 1863 by the botanist Ferdinand von Mueller as published in the work Fragmenta Phytographiae Australiae.[1]
