Description

The shrub is dense and rounded typically growing to a height of 0.6 to 4 metres (2 to 13 ft)[2] and has glabrous branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, ascending to erect phyllodes have a narrowly elliptic shape and can be incurved. They have a length of 4 to 7 cm (1.6 to 2.8 in) and a width of 3 to 4.5 mm (0.12 to 0.18 in) and are semi-rigid and sharply to coarsely pungent and have three distant, raised nerves.[1] It blooms from March to June producing cream flowers.[2] The simple inflorescences occur in pairs in the axils forming cylindrical flower-spikes that have a length of 15 to 25 mm (0.59 to 0.98 in) and a diameter of 3 to 4.5 mm (0.12 to 0.18 in) and are subdensely packed with cream coloured flowers. The pendant, thinly-coriaceous and glabrous seed pods that form after flowering have a linear shape but are raised over and constricted between the seeds. The pods have a length of up to 10.5 cm (4.1 in) and a width of 4 mm (0.16 in) with the seeds arranged longitudinally inside. The slightly glossy black seeds have a broadly elliptic shape with a length of 3 to 4 mm (0.12 to 0.16 in) and an apical aril.[1]

Distribution

It is native to a small area near Peak Charles in Peak Charles National Park in the Goldfields-Esperance region of Western Australia where it is found situated on granite mountain slopes and clay flats growing in sandy soils.[2] The park is located approximately 100 km (62 mi) south of Norseman and the shrub is usually part of low heathland communities.[1]
