Acacia nyssophylla F.Muell., Fragm. 4: 4 (1863)

Dense, intricate shrub, rarely a tree, 0.6–3 m high. Branchlets appressed-puberulous (at least at nodes), glabrescent, scarred where phyllodes have fallen. Phyllodes sessile, inserted on distinct, yellow stem-projections, patent to inclined, straight to shallowly curved, subterete to compressed, mostly 15–35 mm long and 1.5 mm wide, pungent, rigid, dull, glabrous or glabrescent, with 20 rather close, plane, somewhat obscure nerves, with stomata evident; gland mostly 2–7 mm above base. Inflorescences simple, commonly 2 per axil; peduncles 3–10.5 mm long, glabrous or sparsely appressed-puberulous; heads globular, rarely ellipsoid, 3.5–6 mm diam., 12–19-flowered, golden. Flowers 5-merous; sepals commonly free, sometimes to 1/2-united. Pods linear, slightly constricted between seeds, arcuate to once-coiled, 3–6.5 cm long, 2–5 mm wide, firm-chartaceous, longitudinally venose, sparsely appressed-puberulous to glabrous. Seeds longitudinal, lanceolate-oblong or oblong-elliptic, 4–5 mm long, glossy, black; aril large, yellow or orange.

Widely distributed from near Geraldton in south-western W.A., E through S.A., to near Meringur in extreme north-western Vic., N to near Alice Springs, N.T., and mainly in Bourke area of N.S.W. Grows commonly in open scrub or low woodland in loamy soils.

Most closely related to A. colletioides which is most readily distinguished by its phyllodes having 8 widely spaced nerves and the phyllode gland basal. Superficially similar to A. enterocarpa .
