Racosperma acanthocladum (F.Muell.) Pedley
Acacia acanthoclada, commonly known as harrow wattle,[2] is a species of flowering plant in the family Fabaceae and is endemic to southern continental Australia. It is a low, highly branched, spreading and spiny shrub with wedge-shaped to triangular or egg-shaped phyllodes with the narrower end towards the base, and spherical heads of up to 30 flowers, and linear, spirally-coiled pods.
Acacia acanthoclada is a low, highly branched, spreading shrub that typically grows to a height of 0.3–2 m (1 ft 0 in – 6 ft 7 in), and has softly-white branchlets ending in sharp, tapering points. The phyllodes are erect, wedge-shaped to triangular or egg-shaped with the narrower end towards the base, 4–8 mm (0.16–0.31 in) long and 2–4 mm (0.079–0.157 in) wide. The flowers are borne in globe-shaped heads on a raceme 4–5 mm (0.16–0.20 in) in diameter on a peduncle 5–15 mm (0.20–0.59 in) long, the heads usually with 15 to 30 yellow flowers. Flowering occurs from July to December and the pods are linear but spirally coiled, up to 10–20 mm (0.39–0.79 in) long, 2.5–3.0 mm (0.098–0.118 in) wide, leathery, dark brown to black, and glabrous. The seeds are 2–4 mm (0.079–0.157 in) long with a thick aril.[2][3][4][5][6]
The species was formally described in 1863 by Victorian Government Botanist Ferdinand von Mueller in his Fragmenta Phytographiae Australiae, based on plant material collected near Kulkyne.[7][8]
In 1999, Bruce Maslin described two subspecies of A. acanthoclada in the journal Nuytsia and the names are accepted by the Australian Plant Census:[9]
Harrow wattle grows in a variety of vegetation types and is relatively common in Western Australia, South Australia, Victoria and New South Wales.
Both subspecies of Acacia acanthoclada are listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[11][15] but subsp. acanthoclada is listed as "endangered" under the New South Wales Government Biodiversity Conservation Act 2016.[12]
