The 2–9 inflorescences are dark yellow balls, borne in phyllode axils, 10–17 mm (0.39–0.67 in) 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[3][6][7][8]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).

[9] It is named after Dr Hermann Beckler, the botanist on the Burke and Wills expedition in 1861[10] and it was he who collected the type specimen (NSW 47447,[11] found in a "Glen to the gorge Nothungbulla, Hodgson's Basin, near the Barrier Range").

[11][12] The common name refers to the Barrier Range in the Broken Hill area, western New South Wales.
