Description
Acacia anceps is a bushy spreading shrub that typically grows to a height of up to 1–3 m (3 ft 3 in – 9 ft 10 in) and has branchlets that are glabrous and angled near the ends. The phyllodes are usually elliptic to lance-shaped with the narrower end towards the base, mostly 25–65 mm (0.98–2.56 in) long, 8–30 mm (0.31–1.18 in) wide, and leathery, sometimes continuous with the branchlets.
The inflorescences are arranged singly in leaf axils in heads of 50 to 130 golden-yellow flowers on a stout, glabrous peduncle mostly 10–26 mm (0.39–1.02 in) long. Flowering occurs from September to February and the pods are narrowly oblong, crust-like to woody, red to brown straight to curved, normally up to 60 mm (2.4 in) long and 10–15 mm (0.39–0.59 in) wide. The seeds are oblong to elliptic, 4.5–6 mm (0.18–0.24 in) long with a reddish-brown stalk.[3][4][5][6]
Taxonomy
Acacia anceps was first formally described in 1825 by Augustin Pyramus de Candolle in his Prodromus Systematis Naturalis Regni Vegetabilis.[7][8] The specific epithet (anceps) means 'two-sided' referring to the flattened stems.[9]
Distribution and habitat
This wattle is endemic to an area along the south coast of southern Australia, where it grows in coastal dune vegetation or open scrub from the Middle Island of the Recherche Archipelago in Western Australia to the Eyre and Yorke Peninsulas in South Australia.[3][4][5][6]
