The flowers are arranged in racemes up to 80 mm (3.1 in) long with leaf-like bracts on the base, each flower on a pedicel 10–40 mm (0.39–1.57 in) long. The sepals are egg-shaped, about 1.5 mm (0.059 in) long, the corolla yellow, about 10 mm (0.39 in) long. The lower lobes of the corolla are about 4 mm (0.16 in) long with wings up to 1.5 mm (0.059 in) wide. Flowering occurs from November to December or January.[2][3]
