The flowers are in single-flowered partial inflorescences , the inflorescence stalks are shorter than the leaf stalks and strong, the flower stalks are elongated and thick and widened towards the top. The egg-shaped sepals are 8 to 9 cm long, they are hairless, almost leathery, blunt at the tip or rounded and spiky. The crown is purple, hairless, 6 to 7 cm long and 6 cm or more wide.
