Inflorescences 7-12-headed racemes, sometimes growing out with subsequent inflorescences appearing simple; raceme axes 2.5-5.5 cm long; peduncles 2 or 3 per node along raceme axis or in phyllode axils, 6-25 mm long, with bract 1-2 mm long near or above middle, ebracteate at base; heads globular to widely ellipsoid, 4.5-5 mm diam., 35-40-flowered, golden. Flowers 5-merous; sepals free. Pods linear, to 8 cm long, 4 mm wide, chartaceous to thinly coriaceous, glabrous.
