Description

edit

The shrub typically grows to a height of 0.5 to 4 metres (2 to 13 ft)[1] and had a rounded, obconic habit. The glabrous branchlets are sericeous between the ribs and towards the apices. The green to grey-green coloured glabrous phyllodes are soft and flexible. The pungent phyllodes have a length of 7 to 14 cm (2.8 to 5.5 in) and a diameter of 0.5 to 1.2 mm (0.020 to 0.047 in) and has eight broad nerves that are separated by narrow furrows.[2] It blooms from July to September producing yellow flowers.[1] The simple inflorescences occur singly or in pairs in the axils and have an obloid to stoutly cylindrical shape with a length of 8 to 15 mm (0.31 to 0.59 in) packed with golden flowers. The chartaceous seed pods that form after flowering are linear or resemble a string of beads have a length of 3 to 6 cm (1.2 to 2.4 in) and a width of 2 to 2.5 mm (0.079 to 0.098 in). The glossy mottled grey brown to light brown seeds within the pods are arranged longitudinally and have and length of 2 to 3 mm (0.079 to 0.118 in).[2]
