Description

edit

Acacia argyraea is a shrub or tree with smooth grey to brown bark, that typically grows to a height of up to 3 m (9.8 ft) and is covered with silvery, silky hairs. Its branchlets are two- or three-angled, especially near their ends. The phyllodes are narrowly elliptical to elliptical, 40–80 mm (1.6–3.1 in) long, 15–35 mm (0.59–1.38 in) wide and leathery with three to six prominent veins. The flowers are pale yellow, and borne in single spikes in axils 10–25 mm (0.39–0.98 in) long. Flowering occurs in July and August, and the fruit is a flat, linear to lance-shaped pod 60–85 mm (2.4–3.3 in) long, and contains brown, oblong to elliptic seeds 4–6.5 mm (0.16–0.26 in) long.[2][3][4][5][6]

Taxonomy

edit

Acacia argyraea was first formally described in 1970 by Mary Tindale in Contributions from the New South Wales National Herbarium from specimens collected from Nicholson station, in Western Australia in 1967.[6][7] The specific epithet (argyraea) means 'silvery in colour'.[8]

Distribution

edit

This species of wattle is native to an area of the Kimberley region of Western Australia, to the Northern Territory and north western Queensland north of around 20° in latitude,[3] but is considered to be quite rare in Queensland.[9] It is often in found around areas of shale, but also will grow in lateritic and sandy soils.[2]
