Vegetative characteristics

Nymphaea rubra has 15.1 cm long, and 7.9 cm wide rhizomes.[3] The petiolate, orbicular leaves are 25–48 cm wide. The adaxial leaf surface is bronzy red to dark green, and the abaxial leaf surface is dark purple. The leaf venation is very prominent.[4] The petiole is 140 cm long.[3]

Generative characteristics

The flowers are 15–25 cm wide.[5] The four purplish-red sepals are oblong to lanceolate.[6] The 12-20 narrowly oval petals have a rounded apex. The androecium consists of 55 red stamens.[5] The gynoecium consists of 16-21 carpels.[6] The fruit bears 1.85 mm long, and 1.6 mm wide seeds.[5] The peduncle is 116 cm long.[3] The flowers are pleasantly fragrant.[7]

Cytology

The diploid chromosome count is 2n = 56.[3]

One case of the development of a proliferating pseudanthia has been reported for a Nymphaea rubra specimen cultivated in the Botanical Garden of the University of Heidelberg, Germany in 1886.[8]

Generative reproduction

Nymphaea rubra may reproduce an apomictically.[9]
