Acacia oswaldii F.Muell.

Shrub or tree 2–8 m high. Branchlets terete, glabrous, appressed-puberulous or tomentulose, typically with many red resinous micro-hairs. Phyllodes spreading to erect, linear, narrowly elliptic or narrowly oblong-elliptic, straight to recurved, terete to flat, (1–) 2.5–10.5 cm long, (1–) 3–15 mm wide, acute to acuminate, or obtuse and mucronate, coarsely to sharply pungent or innocuous, coriaceous to rigid, occasionally ±glaucous, glabrous, with 3–6 distant raised main veins and with nearly as prominent secondary veins occasionally anastomosing. Inflorescences simple, 2 per axil; peduncles normally 0–0.8 mm long; heads depressed globular, 4.5–5 mm diam., 4–15-flowered, pale yellow. Flowers 5-merous; sepals ¼–⅔-united. Pods linear, openly coiled or twisted, to 31 cm long, 6–12 mm wide, coriaceous to woody, minutely appressed-puberulous and (when young) with many clumps of red micro-hairs. Seeds longitudinal, oblong-elliptic, 6–8 mm long, glossy, dark brown; aril broad and fleshy, yellow-orange.

Widespread and scattered among eucalypts or along edges of mulga country, growing in arid, semi-arid and subtropical areas; mainly in calcareous sands or loam.
