Flowers: Flowers in racemes 3–30 cm long. Flowers caesalpinaceous. Pedicels 8–37 mm long, bracts subulate-lanceolate, 1–4 mm long, caducous as pedicels begin to elongate; bracteoles absent. Calyx lobes yellowish to reddish brown, outer ones ovate to elliptic–lanceolate, the innermost obovate to elliptic–suborbicular, the longest sepal 9.5–13 mm long; margins membranous, lobes 5, imbricate. Corolla of 5 petals, golden yellow to orangish yellow, fading yellow, the standard broadly obovate–flabellate, the others ovate to obovate, the abaxial ones sometimes oblong–elliptic, the longest petal 12–16 mm long.

Ovary superior; styles 5–8 mm long.

Fruit: Pods pendulous; chartaceous; cylindrical; straight or slightly curved 8–15 cm long; often portions sterile and then variably distorted; 7–18 cm long; tardily or not dehiscent; the mesocarp and exocarp separating when fruit fully ribe; the cavity with membranous interseminal septa.
