The flowers are arranged in racemes up to long on a peduncle long, each flower on a pedicel long with leaf-like bracts and linear bracteoles long. The sepals are lance-shaped to elliptic, long, the petals orange-yellow and about long. The lower lobes of the corolla are about long with wings about wide. Flowering mainly occurs from May to August and the fruit is a compressed oval capsule long.[1] [2]
