[1] The hairy branchlets have pale yellow new shoots that age to a silvery colour due to indumentum.

The smooth red to dark brown seed pods that form after flowering resemble a string of beads with a length of 5 to 10 cm (2.0 to 3.9 in) and a width of 8 to 13 mm (0.31 to 0.51 in).

[2] The species was first formally described by the botanist Johann George Luehmann in 1896 as part of the work Reliquiae Muellerianae: Descriptions of New Australian Plants in the Melbourne Herbarium as published in The Victorian Naturalist.

It was reclassified by Leslie Pedley in 2003 as Racosperma tysonii then transferred back to genus Acacia in 2006.

[3] It is native to an area in the Gascoyne, Mid West and Goldfields-Esperance regions of Western Australia where it has a scattered distribution growing in sandy-clay-loam soils often over or around limestone or calcrete.
