[3] The inflorescences are racemose with the axes having a length of 1.5 to 4 centimetres (0.59 to 1.57 in), the cream to pale yellow globular heads containing 20 to 30 flowers have a diameter of 4 to 6 millimetres (0.16 to 0.24 in).

Following flowering dark brown to blackish glabrous seed pods form are constricted at regular intervals resembling a string of beads in shape with a length of 15 to 20 cm (6 to 8 in) and a width of 6 to 8 millimetres (0.24 to 0.31 in).

The shiny black seeds have an oblong to elliptic shape with a length of 5.5 to 8 mm (0.22 to 0.31 in) and a width of 4 to 5 millimetres (0.16 to 0.20 in).

It was reclassified as Racosperma microbotryum in 2003 by Leslie Pedley then transferred back to the genus Acacia in 2014.

[4] There are two recognised variations: It is native to an area in the Wheatbelt, Great Southern and Goldfields-Esperance regions of Western Australia where it grows among rocky outcrops, near watercourses, around salt lakes and along road verges in clay loam or sandy loam soils often over granite.
