Acacia beckleri commonly known as Barrier Range wattle,[1] is a flowering plant in the family Acacia. It is an upright or spreading shrub with green or bluish-green leaves and yellow ball flowers.
Acacia beckleri is a decumbent, spreading or upright shrub high with reddish-brown stems and branches. The phyllodes are oblanceolate to narrowly elliptic, straight or slightly curved. Leaves are green to pale green, faintly veined, long and wide, tapering at the base and rounded or pointed at the end. The 2–9 inflorescences are dark yellow balls, borne in phyllode axils, in diameter and up to 60 individual flowers in each globular cluster on a short, thickened, ribbed stalk. Flowering occurs from May to August and the fruit is a straight, flat, reddish-brown pod, mostly straight-sided to barely and irregularly more deeply constricted between seeds. This plant can be propagated by seed and probably also cuttings.00[2] [3]
Barrier Range wattle was first formally described in 1965 by Mary Tindale and the description was published in Supplement to J.M.Black's Flora of South Australia (Second Edition, 1943-1957).[4] It is named after Dr Hermann Beckler, the botanist on the Burke and Wills expedition in 1861[5] and it was he who collected the type specimen (NSW 47447,[6] found in a "Glen to the gorge Nothungbulla, Hodgson's Basin, near the Barrier Range").[7] The common name refers to the Barrier Range in the Broken Hill area, western New South Wales.[8]
Acacia beckleri grows mainly on slopes in shallow soils in the Eyre Peninsula and Flinders Ranges to Boolcoomata in South Australia and western New South Wales.
