Rigid, diffuse to dense shrub or tree 0.5–3 m high. Branchlets glabrous or sparsely appressed-puberulous and glabrescent, scarred where phyllodes have fallen. Phyllodes sessile, inserted on distinct, yellow stem-projections, patent to ascending, straight to curved, terete, mostly 1.5–3 cm long, 1–1.5 mm diam., subulate, pungent, rigid, glabrous, with 8 strongly raised, lighter coloured nerves and raised stomata; gland basal. Inflorescences simple, 2 per axil; peduncles 1.5-4.5 mm long, glabrous; basal bracts cucullate, semicircular; heads subglobular, often widely ellipsoid, 3–5 mm long, 3–4.5 mm diam., 15–24-flowered; bracteoles peltate. Flowers mostly 5-merous; sepals free. Pods linear, constricted between seeds, 1- or 2-coiled, to 7 cm long, 3–5 mm wide, thin-coriaceous, reticulate, glabrous. Seeds longitudinal, oval to ovate, 3.5–4 mm long, shiny, black; aril nearly enveloping seed, orange or yellow.
Widespread throughout southern Australia from near Geraldton, W.A., E through S.A. and NW Vic. to near Dubbo and Barrigun, N.S.W. Grows in a variety of soils, mainly in mallee scrub or open woodland.
Closely related to A. nyssophylla . Phyllodes superficially similar to those of A. asepala . Also superficially similar to A. subsessilis and A. enterocarpa but readily distinguished by its pods and seeds.
