Erect or spreading shrubs 1-2.5 m high, either dense compact and single stemmed or spreading and openly branched with a number of stems arising from near ground level; branchlets glabrous, terete to slightly angular, flexuose towards the apex. <P>Phyllodes lanceolate, 7-17 cm long, 9-25 mm broad, usually broadest above the middle, falcate, glabrous, pale green, mid-vein obvious, lateral veins rather obscure; glands small on upper margins, 4-15 mm from the base. <P>Inflorescences axillary racemes, shorter than the phyllodes or sometimes paniculate at the ends of branchlets due to phyllode reduction, raceme axis slightly flexuose and glabrous; flower-heads globular, bright yellow, c. 25-30-flowered; bracteoles light brown and conspicuous when in bud; flowers 5-merous. <P>Legumes linear, 9-12.5 cm long, 5-6 mm broad, more or less straight, firmly chartaceous, raised over seeds, glabrous, dark brown; margins slightly constricted between seeds. Seeds longitudinal or slightly oblique in legume, obloid; funicle long, more or less encircling seed in a double fold, gradually expanded into a pale yellowish aril.
