The hairy phyllodes are acuminate with a fine curved and innocuous point that is not rigid and have many closely parallel indistinct nerves.

The subnitid dark brown seeds inside the pods have a broadly elliptic to ovate shape with a length of 4.5 to 5 mm (0.18 to 0.20 in).

[2] The species was first formally described by the botanist George Bentham in 1864 as part of the work Flora Australiensis.

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

A weeping form of the species that grows at Roxby Downs, South Australia bears the common name water myall.
