Description

The erect and loose shrub typically grows to a height of 0.6 to 3.0 metres (2 to 10 ft).[1] The shrub has glabrous, straight, brown-dotted branchlet with persistent stipules that can become tooth-like projections at older nodes. The thin, green, linear phyllodes can sometimes have a narrowly elliptic shape and are straight to shallowly curved. The phyllodes have a length of 7 to 15 cm (2.8 to 5.9 in) and a width of 2 to 5 mm (0.079 to 0.197 in) and have reddish-brown coloured resinous-hairs when young and a prominent midrib.[2] It blooms from August to November and produces yellow flowers.[1] The simple inflorescences have spherical to obloid flower-heads containing 30 to 45 golden coloured flowers. The terete red to brown coloured seed pods that form after flowering areslightly constricted between the seeds. The pods have a maximum length of 6.5 cm (2.6 in) and a width of to around 4 mm (0.16 in). Th oblong, semi-glossy bark brown seeds within the pods have a length of 3.5 to 4.5 mm (0.14 to 0.18 in) with a white aril.[2]
