[5] Flowerheads are globe-shaped and composed of 7-16 pale yellow flowers, on stalks between 10 and 25 mm (0.39 and 0.98 in) long.

Following flowering it will form blackish curved to linear seed pods that are about 6.5 centimetres (2.6 in) in length and 2 to 4 millimetres (0.079 to 0.157 in) wide with thick yellowish margins.

[8] In 2003 it was reclassified as Racosperma truncatum by Leslie Pedley, then transferred back to the genus Acacia in 2016.

[5][9] The species name is taken from the Latin word meaning to cut off, referring to the short blunt end of the phyllodes.

[1] The seeds need to be treated with hot water treatment or lightly scarified prior to planting.
