Generative characteristics[edit]

The flowers, which are only open during daytime, can extend up to 20 cm above the water surface. The four 7 cm long sepals have an acute to obtuse apex. The 25 lanceolate petals have an acute to obtuse apex. The androecium consists of 100 stamens. The gynoecium consists of 11-22 carpels. The globose, 2.5 cm wide fruit bears numerous glabrous, elliptical, 1.75-2.5 mm long, 1-1.5 mm wide seeds.[3]
