Inflorescences 8–16-headed racemes; raceme axes 2–4 cm long, glabrous, pruinose, frequently growing out, enclosed when young by conspicuous imbricate bracts; peduncles 6–10 mm long, slender, glabrous; heads globular, 12–17-flowered, pale yellow to lemon yellow. Flowers 5-merous, sweet-scented; sepals free. Pods normally 6–12 cm long, 6–12 mm wide, thinly coriaceous, commonly pruinose, glabrous.

Popular in cultivation, with many forms, some having very pendulous branchlets, others more upright. See W.R. Elliot & D.L. Jones, Encyclopaedia of Australian Plants 2: 68 (1982) for discussion.
