Phyllodes vertically deflexed, straight, terete, 9- 22 cm long, 1- 1.5 mm diam., long-tapering acuminate, pungent, rigid, glabrous, with 16 closely parallel, raised nerves. Inflorescences simple, 2 per axil; peduncles 3- 6 mm long, glabrous; spikes 7- 10 mm long, 4- 5 mm diam., densely flowered. Flowers 4-merous; sepals free. Pods linear, strongly raised over and constricted between seeds, slightly curved, to 16.5 cm long, 7.5- 8 mm wide, thin-crustaceous, irregularly longitudinally striate, glabrous. Seeds longitudinal, broadly elliptic, 6.5- 7.5 mm long, dull, dark brown to black; aril minute.
Discontinuous, occurring on Pingandy Stn (Ashburton R.) and from Errabiddy Stn (near Gascoyne R.) S to Murgoo Stn (Murchison R.), north-western W.A. Usually grows on loamy alluvial plains in shrubland, often with Mulga ( Acacia aneura ).
Very distinctive on account of its vertically deflexed, terete phyllodes. Relationships uncertain.
