The thinly crustaceous seed pods that form after flowering are tightly irregularly coiled and have a width of 2.5 to 4 mm (0.1 to 0.2 in).

[6] The shiny dark brown seeds are arranged longitudinally in the pods and have an obloid-ellipsoid shape and are 3 to 5 mm (0.1 to 0.2 in) in length with a bright yellow aril.

[7][8] The species was first formally described by the botanist Allan Cunningham in 1832 as part of George Don's work A General History of Dichlamydeous Plants.

[5] The range of the bulk of the population extends from around near Derby in the Kimberley region of Western Australia to the east through the top end of the Northern Territory as far as Rockhampton in eastern Queensland.

Smaller populations are found in arid regions of the Pilbara in the Hamersley Range, in central parts of the Northern Territory and in southwestern Queensland.
