The resinous, sticky, shiny brown pods have a length of 7 to 11 cm (2.8 to 4.3 in) and a width of 7 to 12 mm (0.28 to 0.47 in) and are strongly an commonly irregularly curved.

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